IlETAILEn DESCRIPTION An embodiment of a Holodeck (collectively called "Holodeck Design Parameters") provide ient energy stimulus to fool the human sensory receptors into believing that received energy impulses within a virtual, social and interactive environment are real, providing: 1) lar disparity without external accessories, head-mounted eyewear, or other peripherals; 2) accurate motion parallax, occlusion and opacity hout a viewin° volume simultaneouslv for anv number of viewers· 3) visual focusb b .; .; , h synchronous convergence, accommodation and miosis of the eye for all perceived rays of light; and 4) ging energy wave propagation of sufficient density and resolution to exceed the human sensory "resolution" for vision, hearing, touch, taste, smell, and/or balance.
Based upon conventional technology to date, we are decades, if not ies away from a technology capable of providing for all receptive fields in a compelling way as ted by the ck Design Parameters including the visual, auditory, somatosensory, gustatory, olfactory, and vestibular systems.
In this disclosure, the terms light field and holographic may be used interchangeably to define the energy propagation for stimulation of any sensory receptor response. ·while initial disclosures may refer to examples of electromagnetic and rnechanical energy propagation through energy surfaces for holographic imagery and volumetric haptics, ail forms of sensory receptors are envisioned in this sure.
Furthermore, the principles disclosed herein for energy propagation along propagation paths may be applicable to both energy emission and energy capture.
Many technologies exist today that are often unfortunately confused with holograms including lenticular printing, Pepper's Ghost, glasses-free scopic displays, horizontal ax displays, head-mounted VR and AR displays (HNID), and other such illusions generalized as "fauxlography.'' These technologies may exhibit some of the desired properties of a true aphic display, hmvever, lack the y to stimulate the human visual sensory response in any way sufficient to address at least two of the four identified Holodeck Design Parameters.
These challenges have not been successfully implemented by conventional technology to produce a seamless energy surface sufficient for holographic energy propagation. There are various approaches to implementing tric and direction multiplexed light field displays including ax barriers, hoge!s, voxels, ditTractive optics, view projection, holographic diffusers, rotational mirrors, multilayered displays, time sequential displays, head mounted display, etc., however, conventional ches may involve a compromise on image quality, resolution, angular sampling density, size, cost, safety, frame rate, etc , ultimately resulting in an unviable technology.
To achieve the Holodeck Design Parameters for the visual, auditory, somatosensory systems, the human acuity ofeach of the respective systems is studied and tood to propagate energy waves to sufficiently fool the human sensory receptors.
The visual system is capable of resolving to approximately l arc rnin, the auditory system may distinguish the difference in placement as little as three degrees, and the sornatosensory system at the hands are capable erning points ted by 2 - 12mm.
While there are various and conflicting ways to measure these acuities, these values are sufficient to understand the systems and methods to stimulate perception of energy propagation.
Of the noted sensory receptors, the human visual system is by far the most sensitive given that even a single photon can induce sensation. For this reason, much of this introduction will focus on visual energy wave propagation, and vastly lower resolution energy systems coupled within a disclosed energy waveguide surface may converge appropriate signals to induce holographic sensory perception. Unless otherwise noted, all disclosures apply to all energy and sensory domains.
\Vhen ating for effective design parameters ofthe energy propagation for the visual system given a viewing volume and viewing distance, a desired energy surface may be designed to include many gigapixels of effective energy location density.
For wide viewing volumes, or near field viewing, the design parameters ofa desired energy surface may e ds of xe!s or more of effective energy location density.
By comparison, a desired energy source may be designed to have 1 to 250 effective rnegapixels of energy location density for ultrasonic propagation of tric haptics or an array of 36 to 3,600 effective energy locations for ic propagation of holographic sound depending on input environmental variables. What is important to note is that with a disclosed ectional energy surface architecture, all components may be configured to form the appropriate structures for any energy domain to enable holographic propagation.
However, the main challenge to enable the Holodeck today involves available visual technologies and electromagnetic device limitations. Acoustic and ultrasonic devices are less challenging given the orders of magnitude difference in desired density based upon sensory acuity inthe respective receptive field, although the complexity should not be underestimated. While holographic emulsion exists with resolutions exceeding the desired density to encode interference patterns in static imagery, state-ofthe-art display devices are limited by tion, data throughput and manufacturing feasibility. To date, no singular y device has been able to meaningfully produce a light field having near holographic tion for visual acuity.
Production of a single silicon-based device capable of meeting the desired resolution for a compelling light field display may not cal and may involve extrernely complex fabrication processes beyond the current manufacturing capabilities. The limitation to tiling multiple existing y devices together involves the seams and gap formed by the physical size of packaging, onics, enclosure, optics and a number of other challenges that inevitably result in an unviable technology from an imaging, cost and/or a size standpoint.
The embodiments sed herein may provide a real-world path to building the Holodeck.
Example embodiments will now be described hereinafter with reference to the accompanying drawings, which form a part hereof, and which illustrate exarnple embodiments which may be practiced. As used in the disclosures and the appended claims, the terms "embodiment", "example embodiment", and "exemplary embodiment" do not necessarily refer to a single embodiment, although they may, and various example embodimentsmaybe readily combined and interchanged, without departing from the scope or spirit of e embodiments. Furthermore, the terminology as used herein is for the e of describing example embodiments only and is not intended to be limitations. In this respect, as used herein, the tenn "in" may include "in" and "on", and the terms "a," ''an" and "the" may include singular and plural references. rmore, as used herein, the term "by'' may also mean "from'', depending on the context. Furthermore, as used herein, the term "ir' may also mean "when" or "upon," ing on the context.
Furthermore, as used herein, the words "and/or'' may refer to and encompass any and all possible combinations of one or more of the associated listed items.
Holographic Svstem Considerations: Overview of Light Field Energy Propagation Resolution Light field and holographic display is the result of a plurality of projections where energy surface locations e r, color and intensity information propagated within a viewing volume. The disclosed energy surface provides opportunities for additional information to coexist and propagate through the same surface to induce other sensory system responses. Unlike a stereoscopic display, the viewed position of the converged energy propagation paths in space do not vary as the viewer moves around the viewing volume and any number of viewers may simultaneously see ated objects in real-'vvorid space as if it was truly there. In some ments, the propagation of energy may be d in the same energy propagation path but in opposite directions. For example, energy emission and energy capture along an energy propagation path are both possible in some ments of the present disclosed. is a schematic diagram illustrating variables relevant for stimulation of sensory receptor response. These variables may include surface diagonal 10 l, surface width 102, surface height 103, a detennined target seating distance 118, the target seating field of view field of view from the center of the display 104, the number of intermediate samples demonstrated here as samples between the eyes 105, the average adult inter-ocular separation 106, the average resolution of the human eye in arcmin l 07, the horizontal field of view formed between the target viewer location and the surface width l08, the vertical field of view formed n the target viewer location and the surface height 109, the resultant h01izontal waveguide t tion, or total number of elements, across the surface l l 0, the resultant vertical waveguide t resolution, or total number of elements, across the surface 111, the sample distance based upon the inter-ocular spacing between the eyes and the number of intermediate samples for angular projection n the eyes 112, the angular sampling may be based upon the sample distance and the target seating distance 113, the total resolution Horizontal per waveguide element derived from the angular sampling desired 114, the total resolution Vertical per waveguide element derived from the angular sampling desired 115, device ntal is the count of the detem1ined number ofdiscreet energy sources desired 116, and device Vertical is the count of the detennined number of discreet energy sources desired 117.
A method to understand the desired minimum resolution may be based upon the following criteria to ensure sufficient stimulation of visual (or other) sensory receptor response: e size (e.g., 84" diagonal), e aspect ratio (e.g., 16:9), seating distance (e.g., 128" from the y), seating field of view (e.g., 120 degrees or+/- 60 degrees about the center of the display), desired intermediate samples at a distance (e.g., one additional propagation path between the eyes), the average inter-ocular separation of an adult (approximately 65rnm), and the average tion of the human eye (approxirnately 1 arcmin). These example values should be considered placeholders depending on the specific application design ters.
Further, each ofthe values attributed to the visual sensory receptors may be replaced with other systems to determine desired propagation path parameters. For other energy propagation embodiments, one may consider the auditory 's angular sensitivity as low as three degrees, and the somatosensory system's spatial resolution of the hands as smail as 2 - 12mm.
\Vhile there are s and cting ways to measure these y acuities, these values are ient to understand the systems and methods to stinmlate perception of virtual energy propagation. There are many ways to consider the design resolution, and the below proposed methodology combines tic product considerations with the biological resolving limits of the sensory systems. As will be appreciated by one of ordinary skill in the art, the following overview is a simplification of any such system design, and should be considered for exemplary purposes only.
With the resolution limit ofthe y system understood, the total energy waveguide element density may be calculated such that the receiving sensory system cannot discern a single energy waveguide element from an nt element, given: • Surface Aspect Ratw. . = Width (W). .
Height (H) • Surface Horizontal Size =Surface Diagonal* ( , 1 /( ,H .. z ,/ 1+ lwJ • Surface Vertical Size = Surface Diagonal* ( 1 1 ) '( .W)" ./ l+(H� "' SurfaceHorizontalSize • 1 onzon alf . t z1�· ld· ie . ·i 1.ew = 2 * a .ant ( ) 2 *Seating Distance , · • Ver ica t. face Verticle l [" ld1" 1.e of -17•v zew = - * a an 7. t ( Sur _ Size ) 2 * Seating ce Horizontal Element Resolution = Horizontal FoV * 60 Eye Resolution Vertical Element Resolution= Vertical FoV * ----­60 Eye Resolution The above calculations result in approximately a 32xl8° field of view resulting rn approximately l920xl080 (rounded to nearest format) energy waveguide elements being desired. One may also constrain the variables such that the field of view is consistent for both (u, v) to provide a more r spatial sampling of energy locations (e.g. pixel aspect ratio). The angular ng of the system assumes a defined target viewing volume location and additional propagated energy paths between two points at the optimized distance, given: Inter-Ocular Distance • S le D. - --------------- istance = (Number of Desired lntennediateSamples+1) • Sample Distance Angu ar � amp mg = atan ---"-----l S, z · ( ing Distance) In this case, the inter-ocular distance is leveraged to calculate the sample distance although any metiic may be leveraged to t for appropriate number of samples as a given distance. With the above variables considered, approximately one ray per 0.57° may be desired and the total system tion per independent y system may be ined, given: _ • _ � , Seating FoV Locatwns Per 1:lement(N) = -----­ r Sampling Total Resolution H = N * Horizontal Element Resolution Total Resolution V = N * Vertical Element Resolution With the above scenario given the size of energy surface and the angular resolution addressed for the visual acuity system, the resultant energy surface may desirably e approximately 400k x 225k pixels of energy resolution ons, or 90 xels holographic propagation density. These variables provided are for exemplary purposes only and many other sensory and energy ogy considerations should be considered for the optimization of holographic propagation of . In an additional embodiment, 1 gigapixel of energy resolution locations may be desired based upon the input variables. In an additional ment, l ,000 gigapixels of energy resolution locations may be desired based upon the input variables.

The device 200 may include drivers 230 and electronics 240 for powering and interface to the active area 220, the active area having a dimension as shown by the x and y arrnws. This device 200 does not take into account the cabling and mechanical structures to drive, power and cool components, and the mechanical footprint may be further minimized by introducing a flex cable into the device 200. The minimum footprint for such a device 200 may also be referred to as a mechanical envelope 210 having a dimension as shown by the M:x and M:y arrows. This device 200 is for illustration purposes only and custom electronics s may further decrease the mechanical envelope overhead, but in almost all cases may not be the exact size of the active area of the device. In an embodirnent, this device 200 illustrates the dependency of electronics as it relates to active image area 220 for a micro OLED, DLP chip or LCD panel, or any other logy \vith the purpose of image illmnination.
In some embodiments, it may also be possible to consider other projection technologies to aggregate multiple images onto a larger overall display. However, this may come at the cost of greater complexity for throw distance, minimum focus, optical quality, uniform field resolution, chromatic aberration, thermal ties, calibration, ent, additional size or form factor. For most practical applications, hosting tens or hundreds of these projection s 200 may result in a design that is much larger with less reliability.
For exemplary purposes only, assumrng energy devices with an energy location density of 3840 x 2160 sites, one may determine the number of individual energy devices (e.g., device 100) desired for an energy surface, given: . Total Resolution H • Demces H = ------­ Device Resolution H • Devices. V = ------­Total Resoiution V Device Resolution V Given the above tion considerations, approximately 105 x 105 devices similar to those shown in may be desired. It should be noted that many devices consist ous pixel structures that may or may not map to a r grid. In the event that there are additional sub-pixels or locations within each full pixel, these may be exploited to generate additional resolution or angular density. Additional signal processing may be used to determine how to convert the light field into the correct (u,v) coordinates ing on the specified location of the pixel stmcture(s) and can be an explicit characteristic of each device that is known and calibrated. Further, other energy s may involve a different handling of these ratios and device structures, and those d in the art will understand the direct intrinsic relationship between each of the desired frequency domains. This will be shown and discussed in more detail in subsequent disclosure.
The resulting calculation may be used to understand how many of these individual devices may be desired to produce a full tion energy surface. In this case, approximately 105 x 105 or approximately 11,080 devices may be d to achieve the visual acuity threshold. The challenge and novelty exists within the fabrication of a seamless energy surface from these available energy locations for sufficient sensory holographic propagation.
Summary of Seamless Energv Surfaces: Configurations and Designs for Arravs of Energy Relavs In some embodiments, approaches are disclosed to address the challenge of generating high energy location density from an array of individual devices t seams due to the limitation of mechanical structure for the s. In an embodiment, an energy propagating relay system may allow for an increase the effective size of the active device area to meet or exceed the ical dimensions to configure an array ofrelays and form a singular seamless energy surface.
FIG-. 3 illustrates an embodiment of such an energy reiay system 300. As shown, the relay system 300 may include a device 310 mounted to a mechanical pe 320, \vith an energy relay element 330 ating energy from the device 310. The relay element 330 may be configured to provide the ability to mitigate any gaps 340 that may be produced when multiple mechanical envelopes 320 of the device are placed into an army of multiple devices 310.
For example, if a device's active area 310 is 20mm x 10mm and the mechanical envelope 320 is 40mm x 20mm, an energy relay element .DO may be designed with a ication of2:1 to produce a tapered form that is approximately 20mm x 10mm on a minified end (arrmv A) and 40mm x 20mm on a magnified end (arrow B), providing the y to align an array of these elements 330 together seamlessly out altering or colliding with the mechanical pe 320 of each device 310. Mechanically, the relay elements 330 may be bonded or fused together to align and polish ensuring minimal seam gap 340 between devices 310. In one such embodiment, it is possible to achieve a seam gap 340 smaller than the visual acuity limit of the eye. illustrates an example of a base structure 400 having energy relay elements 410 formed together and securely fastened to an additional mechanical ure 430. The mechanical structure of the seamless energy surface 420 provides the ability to couple nmltiple energy relay elements 410, 450 in series to the sarne base structure through bonding or other mechanical processes to mount relay elements 410, 450. In some embodiments, each relay t 410 may be fused, bonded, adhered, pressure fit, aligned or otherwise attached together to form the resultant seamless energy surface 420. In some embodiments, a device 480 may be mounted to the rear of the relay element 410 and aligned passively or actively to ensure appropriate energy location alignment within the ined tolerance is maintained.
In an embodiment, the seamless energy surface comprises one or more energy locations and one or more energy relay element stacks comprise a first and second side and each energy relay t stack is ed to form a singular seamless display surface directing energy along propagation paths extending bet\veen one or more energy locations and the seamless display surface, and where the separation between the edges of any two adjacent second sides of the terminal energy relay ts is less than the minimum perceptible contour as defined by the visual acuity ofa human eye having better than 20/40 vision at a distance greater than the width of the singular seamless display surface.

In an embodiment, the seamless energy e is ured with energy relays that comprise two or more first sides for each second side to both receive and emit one or more energy domains simultaneously to provide bi-directional energy ation hout the system.
In an embodiment, the energy relays are provided as loose coherent Introduction to Component Engineered Structures: Disclosed Advances in Transverse Anderson Localization Energy Relavs The properties of energy relays may be significantly optimized ing to the principles disclosed herein for energy relay elements that induce Transverse Anderson Localization. Transverse Anderson Localization is the propagation of a ray transported through a transversely ered but longitudinally consistent material.
This implies that the effect of the materials that produce the Anderson Localization phenomena may be less impacted by total internal reflection than by the randomization between multiple-scattering paths where wave interference can completely limit the propagation in the transverse orientation while continuing in the longitudinal orientation.
Of significant additional benefit is the elimination of the ng of traditional multi-core l fiber materials. The cladding is to functionally eliminate the scatter of energy between fibers, but simultaneously act as a barrier to rays of energy thereby reducing transmission by at least the core to clad ratio (e.g., a core to clad ratio of 70:30 \Vill transmit at best 70(;.,o of ed energy transmission) and additionally fom1s a strong pixelated patterning in the propagated energy. rates an end view of an example of one such non-Anderson Localization energy relay 500, wherein an image is relayed through multi-core optical fibers where pixilation and fiber noise may be exhibited due to the intrinsic properties of the optical fibers. \.Vith ional multi-rnode and multi-core optical fibers, relayed images may be intrinsically pixelated due to the ties oftotal internal reflection ofthe discrete array of cores where any cross-talk between cores will reduce the modulation transfer function and increase blurring. The resulting imagery produced with traditional multi-core l fiber tends to have a residual fixed noise fiber pattern similar to those shown in FIG.
FIG. SB, illustrates an example of the same relayed image 550 through an energy relay comprising materials that exhibit the properties of Transverse Anderson Localization, where the relayed pattern has a greater density grain structures as compared to the fixed fiber n from FIG. SA. In an embodiment, relays comprising randomized microscopic component engineered structures induce erse Anderson Localization and transport light more efficiently with higher propagation of resolvable resolution than commercially available multi-mode glass optical fibers.
There is significant advantage to the Transverse on Localization material properties in terms of both cost and weight, where a similar optical grade glass material, may cost and weigh upwards of 10 to 100-fold more than the cost for the same material generated within an ment, wherein disclosed systems and methods comprise randomized copic component engineered structures trating significant opportunities to improve both cost and quality over other technologies known in the art.

In an embodiment, multiple energy domains may be configured within a single, or between multiple Transverse Anderson Localization energy relays to direct one or more sensory holographic energy propagation paths including visual, acoustic, tactile or other energy domains.
In an ernbodiment, the seamless energy e is ured with Transverse Anderson Localization energy relays that comprise two or more first sides for each second side to both receive and emit one or more energy domains simultaneously to e ectional energy propagation throughout the system.
In an embodiment' the Transverse Anderson Localization ener0v relavs areb.; .; configured as loose coherent or flexible energy relay elements.
Considerations for 4D tic Functions: Selective ation of Energy through Holographic Waveguide Arrays As discussed above and herein throughout, a light field display system generally includes an energy source (e.g., illumination source) and a seamless energy surface configured with ient energy location density as articulated in the above discussion. A plurality of relay elements may be used to relay energy from the energy devices to the ss energy surface. Once energy has been delivered to the seamless energy surface with the ite energy location density, the energy can be propagated in accordance with a 4D plenoptic function through a disclosed energy waveguide system. As will be appreciated by one of ordinary skill in the art, a 4D plenoptic function is well known in the art and will not be elaborated further herein.
The energy waveguide system selectively propagates energy through a ity of energy locations along the seamless energy surface representing the spatial nate of the 4D plenoptic function with a structure configured to alter an r ion of the energy waves passing through representing the angular component of the 4D plenoptic function, wherein the energy waves propagated may converge in space in accordance with a plurality of propagation paths directed by the 4D plenoptic on.
Reference is now made to illustrating an example of light field energy surface in 4D image space in accordance with a 4D plenoptic function. The figure shows ray traces of an energy surface 600 to a viewer 620 in describing how the rays of energy converge in space 630 from various positions within the viewing volume. As shown, each waveguide element 610 defines four ions of information describing energy propagation 640 through the energy surface 600. Two l ions (herein refoITed to as x and y) are the al plurality of energy locations that can be viewed in image space, and the angular ents theta and phi (herein referred to as u and v), which is viewed in virtual space when projected through the energy waveguide array. In general, and in accordance with a 4D plenoptic function, the plurality ofwaveguides (e.g., ts) are able to direct an energy location from the x, y dimension to a unique location in virtual space, along a direction defined by the u, v angular component, in forming the holographic or light field system described herein.
However, one skilled in the art will understand that a significant challenge to light field and holographic display technologies arises from uncontrolled propagation of energy due designs that have not accurately accounted for any of diffraction, scatter, diffusion, angular direction, calibration, focus, collimation, curvature, unifom1ity, elernent cross-talk, as well as a multitude of other parameters that contribute to decreased effective tion as well as an inability to accurately converge energy with sufficient fidelity.

System and Methods for Production of Transverse Anderson Localization Energy Relays [0(H 19] While the Anderson localization principle was introduced in the 1950s, it wasn't until recent technological breakthroughs in materials and processes that allowed the principle to be explored practically in l transport. Transverse Anderson localization is the propagation of a wave transported through a transversely ered but longitudinally invariant material without diffusion of the wave in the transverse plane.
Within the prior art, Transverse Anderson localization has been ed through experimentation in which a fiber optic face plate is fabricated through drawing millions of individual strands of fiber 'vvith different refractive index (RI) that were mixed randomly and fused together. \,Vhen an input beam is scanned across one ofthe surfaces of the face plate, the output beam on the opposite e follows the transverse position of the input beam. Since Anderson localization exhibits in disordered mediums an absence of ion of waves, some of the fundamental physics are different when compared to ordered l fiber relays. This implies that the effect of the optical fibers that e the Anderson localization phenomena are less ed by total al reflection than by the randomization of n multiple-scattering paths where wave interference can completely limit the propagation in the transverse orientation while continuing in the udinal path.
In an embodiment, it may be possible for Transverse Anderson Localization materials to transport light as well as, or better than, the highest quality commercially available multimode glass image fibers with a higher MTF. \Vith multimode and multicore optical fibers, the relayed images are intrinsically pixelated due to the properties of total al reflection of the te array of cores where any cross-talk between cores will reduce MTF and increase blurring. The resulting imagery produced \vith multicore optical fiber tends to have a residua! fixed noise fiber pattern, as rated in . By contrast, FIG-. SB illustrates the same relayed image through an example material sample that exhibits the properties of the erse Anderson Localization principle where the noise pattern appears much more like a grain structure than a fixed fiber pattern.
Another advantage to optical relays that exhibit the on localization phenomena is that it they can be fabricated frorn a polymer material, resulting in d cost and weight. A similar optical grade material, generally made of glass or other similar rnaterials, rnay cost ten to a hundred (or rnore) tiines more than the cost of the same dimension of material generated with polymers. Further, the weight of the polymer relay optics can be 10-l00x less given that up to a majority of the density of the mate1ial is air and other light weight plastics. For the avoidance of doubt, any material that exhibits the Anderson localization property may be included in this disclosure herein, even if it does not meet the above cost and weight suggestions. As one skilled in the art will tand that the above suggestion is a single embodiment that lends itself to significant commercial viabilities that similar glass products exclude. Of additional benefit is that for Transverse Anderson zation to work, optical fiber cladding may not be needed, which for traditional multi core fiberoptics is required to prevent the scatter of light between fibers, but simultaneously blocks a portion of the rays of light and thus reduces transmission by at least the core to clad ratio (e.g. a core to clad ratio of 70:30 will transmit at best 70% of received illumination).
Another benefit is the ability to produce many smaller parts that can be bonded or fused \vithout seams as the material fundamentally has no edges in the traditional sense and the merger of any two pieces is nearly the same as generating the component as a singular piece depending on the process to merge the two or more pieces together. For large scale ations, this is a significant t for the ability to manufacturer t massive tructu re or g costs, and it provides the ability to generate single pieces of material that would ise be impossible with other methods. ional plastic optical fibers have some of these benefits but due to the cladding, generally still involve a seam line of some distances.
The present disclosure includes s of manufacturing materials exhibiting the Transverse Anderson Localization phenornena. A process is proposed to construct relays of omagnetic energy, acoustic energy, or other types of energy using building blocks that consist of one or more component engineered structures (CES). The term CES refers to a ng block component with ic engineered iies (EP) that include, but are not d to, material type, size, shape, refractive index, -ofmass , charge, weight, absorption, ic moment, among other properties. The size scale of the CES may be on the order of wavelength of the energy wave being relayed, and can vary across the mi!li-scale, the micro-scale, or the nano-scale. The other EP's are also highly ent on the \vavelength of the energy wave.
Transverse on Localization is a general wave phenomenon that applies to the transport of electromagnetic waves, acoustic waves, quantum waves, energy waves, among others. The one or more building block strnctures required to form an energy wave relay that exhibits Transverse Anderson zation each have a size that is on the order of the coITesponding wavelength. Another critical parameter for the building blocks is the speed of the energy wave in the materials used for those building blocks, which es refractive index for electromagnetic waves, and ic impedance for acoustic waves. For example, the ng block sizes and refractive indices can vary to accommodate any frequency in the electromagnetic spectrum, from X-rays to radio waves.
For this reason, discussions in this disclosure about optical relays can be generalized to not only the full electromagnetic spectrum, but to acoustical energy and other types of energy. For this reason, the use of the terms energy source, energy surface, and energy relay will be used often, even if the discussion is focused on one particular form of energy such as the visible electromagnetic spectrum.
For the avoidance of doubt, the material quantities, process, types, refractive index, and the like are rnerely exernplary and any optical material that exhibits the Anderson localization property is included herein. Further, any use of disordered materials and processes is included herein.
It should be noted that the principles of optical design noted in this disclosure apply generally to all forms of energy relays, and the design implementations chosen for specific products, markets, form factors, mounting, etc. may or may not need to address these geometries but for the purposes of simplicity, any approach disclosed is inclusive of all potential energy relay materials.
In one embodiment, for the relay of visible electromagnetic energy, the size ofthe CES should be on the order of l micron. The materials used for the CES can be any optical material that exhibits the optical qualities desired to include, but not d to, glass, plastic, resin and the like. The index of refraction of the materials are higher than l, and if t\vo CES types are chosen, the difference in tive index becomes a key design parameter. The aspect ratio of the rnateri.al may be chosen to be ted, in order to assist wave propagation in a longitudinal direction.
The formation of a CES may be eted as a destmctive process that takes formed materials and cuts the pieces into a desired shaped formation or any other method known in the art, or additive, where the CES may be grown, printed, fom1ed, melted, or produced in any other method known in the art Additive and destructive processes may be combined for further control over fabrication. These pieces are now constructed to a ied structure size and shape.
] In one embodiment, for electromagnetic energy relays, it may be possible to use optical grade bonding agents, epoxies, or other known optical materials that may start as a liquid and form an optical grade solid structure through various means including but not limited to UV, heat, time, among other processing parameters. In another embodiment, the bonding agent is not cured or is made of index matching oils for flexible applications. Bonding agent may be applied to solid structures and non-curing oils or optical liquids. These materials may exhibit n tive index (RI) properties. The bonding agent needs to match the RI of either CES material type 1 or CES material type 2.
In one embodiment, the RI ofthis optical bonding agent is 1.59, the sarne as PS. In a second ment, the RI of this optical bonding agent is 1.49, the same as PwrMA.
In one embodiment, for energy waves, the bonding agent may be mixed into a blend of CES material type l and CES material type 2 in order to ively cancel out the RI of the material that the bonding agent RI matches. For exemplary purposes only, if CES types PS and PMMA are used, and PS matches the RI of the bonding agent, the result is that PS now acts as a spacer to ensure randomness n PMMA and the bonding agent. Without the presence of the PS, it may be possible that there will not be sufficient randomization between Pl\'1:MA and the RI of bonding agent. The bonding agent may be thoroughly intennixed such that no regions are unsaturated which may require a certain amount oftime for saturation and desired viscous properties. Additional constant agitation may be implemented to ensure the appropriate mixture of the materials to ract any tion that may occur due to various ies of materials or other material properties.
It may be required to perform this process in a vacuum or in a chamber to evacuate any air bubbles that may form. An onal methodology may be to introduce vibration during the curing s.
An alternate method provides for three or more CES with additional fom1 characteristics and EPs.
In one embodiment, for electromagnetic energy relays, an additional method provides for only a single CES to be used with only the bonding agent, where the RI of the CES and the bonding agent differ, and sufficient intermixing occurs between the single CES and the bonding agent.
An additional method provides for any number of CESs and includes the intentional introduction of air bubbles.
In one embodiment, for electromagnetic energy relays, a method provides for multiple bonding agents with independent desired Rls, and a process to intermix the zero, one, or more CES's as they cure either separately or together to allow for the formation of a completely intermixed re. Two or more separate curing methodologies may be leveraged to allow for the ability to cure and intermix at different als with different tooling and procedural methodologies. In one embodiment, a UV cure epoxy with a RI of 1.49 is ixed with a heat cure second epoxy with a R1 of 1.59 where constant ion of the materials is provisioned with alternating heat and UV treatments with only sufficient duration to begin to see the formation of solid stmctures from within the larger e, but not long enough for any large particles to form, until such time that no agitation can be continued once the curing process has nearly completed, whereupon the curing processes are implemented simultaneously to completely bond the materials together In a second embodiment, CES with a RI of 1.49 are added. In a third embodiment, CES with both a R1 of 1.49 and 1.59 both added.
In another ment, for electromagnetic energy relays, glass and plastic materials are intem1ixed based upon their tive RI properties.
In an additional embodiment, the cured rnixture is formed in a rnold and after curing is cut and polished. In another embodiment, the materials leveraged will re- liquefy with heat and are cured in a first shape and then pulled into a second shape to include, but not limited to, tapers or bends.

The CES material type l (72) and CES material type 2 (74) both have the engineered property of being elongated - in this embodiment, the shape is elliptical, but any other elongated or engineered shape such as cylindrical or stranded is also possible. The elongated shape allows for channels of um engineered property variation 75.
For an embodiment for visible omagnetic energy relays, implementation 70 may have the bonding agent replaced with a refractive index matching oil 76 with a refractive index that matches CES material type 2 (74) and placed into the flexible tubing enclosure 78 to maintain flexibility of the mixture of CES material type 1 and CES material 2, and the end caps 79 would be solid optical relays to ensure that an image can be d from one surface of an end cap to the other. The elongated shape of the CES materials allows channels of minimum refractive index variation 75 Multiple instances of 70 can be interlaced into a single surface in order to form a relay cornbiner in solid or flexible form.
In one embodiment, for visible electromagnetic energy relays, l instances of70 may each be connected on one end to a display device showing only one of many specific tiles of an image, with the other end of the optical relay placed in a regular mosaic, arranged in such a way to y the full image with no able seams. Due to the properties of the CES materials, it is additionally possible to fuse multiple the le optical relays within the mosaic together. illustrates a cutaway view of a rigid implementation 750 of a CES Transverse Anderson Localization energy relay. CES al type 1 (72) and CES rnaterial type 2 (74) are intermixed with bonding agent 753 which matches the index of refraction of material 2 (74).

In an embodiment for visible electromagnetic energy relays, illustrates a y view in the transverse plane the inclusion of a DEMA sional extra mural absorption) CES, 80, along with CES material types 72, 74 in the longitudinal direction of one exemplary material at a given percentage of the overall mixture of the material, which controls stray light, in accordance with one embodiment of the t disclosure for visible electromagnetic energy relays.
The additional CES materials that do not transmit light are added to the mixture(s) to absorb random stray light, r to EMA in traditional optical fiber technologies, only the absorbing als are included within a dimensional lattice and not contained within the longitudinal dirnension, herein this material is called DEMA, 80.
Leveraging this approach in the third dimension provides far more control than previous methods of implementation where the stray light control is much more fully randomized than any other entation that includes a stranded EMA that ultimately reduces overall light transmission by the percent of the area of the surface of all the optical relay components, whereas the DEMA is intermixed in the dimensional lattice that effectively controls the light transmission in the udinal direction without the same ion of light in the transverse. The DEMA can be provided in any ratio of the overall mixture. In one ment, the DEMA is l % of the overall mixture of the material. In a second embodiment, the DEMA is 10�� of the overall mixture of the material.
In an additional embodiment, the two or rnore materials are treated with heat and/or pressure to perform the bonding process and this may or may not be completed with a rnold or other similar forming process known in the art. This may or may not be applied within a vacuum or a vibration stage or the like to eliminate air bubbles during the melt process. For example, CES with material type PS and PJvfNIA may be intermixed and then placed into an appropriate mold that is placed into a uniform heat distribution environment capable ofreaching the melting point of both materials and cycled to and from the respective temperature without causing damage/fractures due to exceeding the maximum heat elevation or declination per hour as dictated by the material properties.
For processes that require intermixing materials with additional liquid bonding agents, in consideration of the variable specific densities of each material, a process of constant rotation at a rate that ts separation of the materials may be illustrates one such method 90 to intennix one or more CES material types 72, 74 within a two part mixture 98 independently with each of the solutions 72, 74 at the m ratios within a system where the nozzles from chambers 94, 96 of each separate mixture meets at a central point 97 to appropriately mix each part of the CES mixture 98 together to form an ideal ratio of CES and bonding agent to allow for appropriate curing with all ed engineered ty ratios rnaintained within a single apparatus, in accordance with one ment of the present disclosure. A linked plunger 92 provides the ability to mix these materials 72, 74 er simultaneously without the additional need for measurements or mixture.
] An additional embodiment includes the ability to use a two-part mixture where each liquid contains one or more of CES materials individually such that when mixed together, all als are provided in the correct and appropriately saturated ratios.
In one specific embodiment, both intermixed materials are placed side by side with linked rs or other methods for applying even re, and nozzles forcing both parts of the mixture to mix with even proportions such that when the plunger or other method for producing the pressure to mix both materials together is activated, the ive mixture includes the exact amount of each CES material as well as the appropriate mixture of the rt medium.
An additional ment provides the ability to create multiple , formed, produced or otherwise materials and use chemical, heat or the like processes to fuse or bond these individual elements together as if they had been produced simultaneously without separate processes to facilitate ical requirements and practical ses. illustrates a process 100 wherein a mixture of CESs 72, 74 and UV sensitive bonding agents l03 are intermixed together in a mixing r 102 and an apparatus controls the release of the mixture of the ials h a nozzle with a predetermined diameter and a high intensity UV laser i04 is focused on the solution near the exit of the nozzle where arbitrarily long threads 108 of the solid cured material 106 may be formed wherein the longitudinal orientation of the thread exhibits CES ordering and the transverse orientation of the threads exhibits CES disordering, in accordance with one embodiment of the present disclosure.
An additional embodiment provides the ability to cure the mixture of CES material types 72, 74 using epoxy or another bonding agent to include als, heat or the like, and rapidly cure thin strands of the mixture maintaining the longitudinal ordering and transverse disordering at any desired diameter of thickness such that a single strand 'vvith any length may be produced. An exemplary application of this includes a l.JV fastcure epoxy ixed with the appropriate ratio of CES material type 1 (72) and CES material type 2 (74) and a nozzle that distributes the mixture at the appropriate er facilitated by a constant pressure for the controlled release of the mixture wherein the high intensity UV laser 104 is focused at the exit of the mixture such that upon contact with the UV light, a solid is formed and the constant pressure of the material exiting the nozzle produces an arbitrary length strand of the material. This process may be performed with any method required to cure ing time, temperature, chemicals and the like. FIG. l 0 illustrates one exemplary implementation of this process. It should be noted that many of these materials exhibit limited sensitivity to UV light, so that either extremely high ities are required for fast cure, or other implementations are introduced to perform this on depending on the materials leveraged in the mixture.
In an embodiment ofthe above, multiple strands are collected together and fused together h methods known in the art including light, time, temperature, chemicals and the like.
An additional embodiment uses no additional bonding agents. This may or rnay not be implemented in the presence of a gas or liquid in order to maintain a loose 'sand-like' mixture of the CESs 72, 74 t the uction of air, but rather a different gas/liquid that may be more appropriate to encourage the propagation ofenergy according to the transverse Anderson localization ple. This may include one or more additional CES materials and may include one or more gasses/liquids.
This application may be performed within a vacuum or a sealed nment. With any implementation methodology, the randomization of CESs is significantly increased from that of other irnplementations that are the current state of the art fom1ing icantly increased disordering in the final structure. Whether the liquid bonding material cures into a solid or remains liquid, a three-dimensional e of CESs are created with a geometry consistent with sed Transverse Anderson Localization oflongitudinal energy waves as discussed previously.
There may be advantages of this approach where CES als can be ively produced and mixed cost effectively and in bulk quantities without the necessity for any custom fabrication processes required to arrange the material into an intermediate form factor.
Further, for processes that involve solid ures, the ability to form structures through molds or the like is extremely powerful for increased efficiency of production and can result in sizes and shapes that were previously not possible. It is also possible to premix the bonding agents with the CESs and can be painted onto any surface or a plethora of other potential implementation methodologies. lA illustrates a radially symmetric cylindrical building block 110 composed of two alternating CESs 72, 74, in accordance with one embodiment of the present disclosure.
In an embodiment for visible electromagnetic energy relays, it is possible to fabricate diffractive, refractive, gradient index, binary, aphic or Fresnel-like structures by generating alternating layers of radially symmetric and non-uniform thicknesses of CESs 72, 74 with, for e, a refractive index ence of approximately 0.1. This value can vary depending on optical configuration. The fabrication s of such an element rnay leverage the principles of Transverse on Localization or may leverage the ques provided in this discussion to produce two rnaterials without explicit ization. The prescription for these elements may vary spatially in either the transverse or longitudinal orientations and may include machined surface profiles or non-uniform spacing bet\..veen individual layers.
One such method provides the ability to simply cure bonding materials with two or more differentiated EP's in an alternating methodology such that each layer forms around a previously cured region and grows radially to a defined diameter. This diameter may be constant, variable, or random depending on the requirements for the system. The cylinders can be used as building blocks for more cornplex structures.
It is possible to build substructures of one or more CES by employing the properties of a transient biaxial material such as, but not limited to, biaxial polystyrene, where the molecules are frozen by rapid cooling into hed positions. Heating the material above a transition temperature will deactivate the transient state, causing the material to shrink, sometimes by a factor of two or more. The method comprises (a) providing one or more CES, (b) forming a medium by at least one of an additive, subtractive, or isolated process, the additive s includes adding at least one CES to a transient structure, the ctive process includes producing voids or an inverse structure in a transient structure to later form \vith at least one CES, and the isolated process includes ering at least one transient structure in the absence or removal of addition of a CES, and (c) forming an assembly and deactivating the transient mate1ial inducing an increase of al property variation along a first plane of an assembly relative to a decrease of material property variation along a second plane of an assembly to achieve erse Anderson Localization.
] FIG. llB shows the subtractive process 115 in which material is removed from a biaxial material and two CES materials 72, 74 are added to a hole in a lly stretched material 1153, where there may or may not be a bonding agent applied. The CESs 72, 74 may be simple pheres that are commercially available but each exhibit at least one critical EP. \Vith relaxation of the biaxial material 1154 after bringing the entire system near the melting point of all materials within the biaxial material, and contraction of the hole, the CES's 72, 7 4 dimensions become elongated in one direction, and cted in the other. Further, the spatial ordering of CESs 72, 74 has been slightly randomized but essentially preserved in such a way that the ion in EP is much less in the direction along the direction of the elongation than in any orthogonal direction.
In an additional embodiment of FIG-. 1 lB, the lly stretched material is subtractively formed to produce a plurality of holes with a first average diameter and a first average density spacing, and then two CESs 72, 74 are added before or after relaxing the biaxial material to result in a second e diameter and a second average density spacing, \vherein the second average y spacing is significantly increased from the first average density spacing and the second e diameter is significantly lmver than the first average diameter, and the thickness of the formed medium has increased resulting in decreased variation in the EP in the longitudinal orientation.
In an embodiment, the method may r comprise (d) generating several assemblies of step (c) with different EPs such as dimensions, size, refractive index, and volume, and generating several compound formed medium from step b; (e) pairing an assembly and a compound-formed medium together to form a unit collectively called a sub-structure, where one or more sub-structures can have one or more EP variations for a first and second plane; (f) generating additional variation with the addition of one or more N CES, each denoted CESi where i is 1 or greater, (g) g a medium of one or more sub-structures and CESt, where the fonning step randomizes one critical EP parameter EPc (such as index of refraction for the embodiment of electromagnetic waves), along the one or more sub-structure's first plane resulting in a first compound medium EPc variability, with a different EP (such as shape) ng a second compound medium EPc variability along the one or more sub-structure's second plane, n the one or more substmcture's second plane is different from the one or more sub-stmcture's first plane, and wherein the second compound medium EPc variability is lmver than the first compound rnedium EPc ility due to the one or more mcture EP and the CESt engineered property; and (h) forming a compound assembly using the compound medium such that the one or more sub-structure's first plane is the transverse orientation of the compound assembly and the one or more sub-structure's second plane is the udinal orientation of the compound assembly, wherein energy waves propagating to or from an entrance to an exit of the compound assembly have higher transport efficiency in the longitudinal orientation versus the transverse ation and are spatially localized in the transverse orientation due to the nd engineered properties and the resultant compound EPc variability. [0(H92] In an embodiment, step (c) or step (h) may include g or other form of processing to deactivate the transient molecular state of the materials within the assembly, wherein the arrangement, density, and EP of the transient materials are varied in at least one of the erse orientation or the longitudinal orientation, thereby causing the assembly during heat treatment or other sing to naturally taper or cause dimensional variations along at least one of the transverse orientation or the longitudinal orientation of the assembly to e various energy relay geometries that \vould have otherwise ed complex cturing processes that maintain the appropriate ordering for energy wave transport efficiency. [0(H93] FIG-. 12 illustrates a perspective view 120 of a cylindrical structure with 20 layers ofdifferent CESs, where one or more critical EPs may vary from layer to layer, and where layers may vary in thickness. The structure can be built to implement a steering of the energy wave through the mate1ial.
In an embodiment for visible electromagnetic energy relays, it is possible to leverage multiple materials with multiple refractive indices that may or may not be of the same thickness perregion as the al radiates from the center ofthe optical material.
With this method, it is le to leverage the optical properties of the material to alter steer angles of light in ermined ways based upon the material properties per designed region. FIG-. 12 illustrates one such embodiment wherein 20 als with different refractive indices are implemented such that there is an input ray 122 and an output ray 124 that alters as a function of the EP ofeach of the materials contained within the l relay element.
The structure of can be built up in layers. The outside surface of each of the previously layered materials can be coated with a CESi layer 'vvith a dimension at or below the desired thickness of each radial layer in combination with a g material with the appropriate set of EPs. When the bonding agent is nearly cured and tacky to the touch, the next layer may be formed by applying the next CESi 1 layer as a coat to the previous bonding agent layer until dry. It is also a potential implementation that this manufacturing process requires constant rotation of the optical build up to ensure a consistent radially concentric structure is formed.
In an embodiment for visible electromagnetic energy relays, the critical ered property is refractive index (RI), and the CESs are leveraged with alternating Ris to coat the outside of each of the previously layered materials with a shape diameter at or below the desired thickness of each radial layer in combination with a bonding al of (near) identical RI properties. \Vhen the bonding agent is nearly cured and tacky to the touch, the next layer of a second (or greater) Rl al is applied to coat the previous bonding agent with a new layer until dry. It is also a potential implementation that this manufacturing process requires constant rotation of the optical build up to ensure a tent radially concentric structure is formed and the structure begins with a center optical 'core' matching one of the two als with the same or r thickness to the desired thickness per radial layer By applying the d RI bonding agent to each microsphere layer, the CES effectively become optically transparent spacers and the bonding agent is used to consistently form a material for the next concentric layer to bond to. In one such embodiment, each microsphere is approximately lum in diameter with a first RI of 1.49 and a first bonding agent with RI of 1.49 and a second rnicrosphere with a second RI of 1.59 and a second bonding agent with an RI of 1.59 and the complete diameter of the constructed ly concentric materials forms a 60mm diameter optical material.
] In a further embodiment of the previously sed ly concentric microsphere build up methodology, a second approach is bed wherein the bonding agents are of the second (or more) RI to form a disordered Anderson localization approach vs. the previously disclosed ordered approach. In this fashion, it is possible to then randomize the transmission of the rays of light to increase the theoretical resolution of the optical system. illustrates perspective views for a spiral production process 130 'vvhich leverages sheets of two CESs 72, 74, in accordance with one embodiment of the present disclosure. A CES material type 72, 74 is arranged to lie end-to-end and then bonded into sheets 132 or 134, respectively, and ed with a predetermined ess.
An additional methodology involves a spiral fabrication s where sheets 132 and 134 are layered and bonded together to form a single sheet 753 that has a first set of critical EPs on one side and a second set of critical EPs on the other side. These materials are then roiled in a spiral until a specified diameter is reached leveraging various mechanical and/or fabrication methods to produce the resultant energy relay geometry.
In an embodiment for visible electromagnetic energy relays, the spiral approach involves the use of CESs with a predetermined thickness and a bonding agent the same RI as one of the two CESs 72, 74 to form sheets of intermixed CESs and bonding agents wherein the CESs are leveraged to determine sheet thickness and the bonding agents are leveraged to hold the CESs together in a flexible sheet, but not to exceed the desired thickness of the individual layers. This is repeated for a second (or more) CES with a second RI.
Once the individual sheets are fabricated at a em1ined length (the length of each of the resultant energy relay elements) and width (the end thickness or diameter after spiraling both materials together), a thin layer of the bonding agent with one or more critical EPs referred to as EP 1 is applied to 132, followed by the mating of 134 to align to 132 t the bonding agent being allowed to cure. 134 then has a bonding agent with one or more EPs referred to as EP 2 applied in a thin layer on top of the assembly and not yet cured. The resulting stack of 132, bonding agent withEP 1, 134, and bonding agent 'vvith EP 2 is then rolled in a spiral to form the resulting energy relay element, and through this process any excess bonding agent material is forced out of either of the two open ends before final curing.
It is additionally possible for any of the above methods to produce the sheets in a non-uniform thickness to e a variable thickness to the concentric rings for specific functional es.
] In an embodiment for visible electromagnetic energy relays, where the critical ered ty is refractive index, it is possible to calculate the directionality of each optical my through a determined thickness of ed material, and then determine the relative thickness for the concentric rings to steer certain rays at certain angles depending on the optical requirements. A wedge ch to the sheet will result in a constantly increasing thickness to each radial ring, or a non-unifom1 thickness across the sheet will produce random changes in thickness ofthe radial rings.
As an alternative to ng two sheets, each one containing a single CES and a single bonding agent, a single sheet layer 135 can be created which contains two or more CESs 72, 74 arranged in an aced -end configuration 135 as shown in A bonding agent with EP l is used to hold the two als together The same bonding agent, or a different one with EP 2, can be applied to the sheet when it is roiled into a spiral to form the resulting energy relay element, and h this process any excess bonding agent material is forced out ofeither of the two open ends.
An additional method ofthe above where the same process is ed, but the sheets are made of mismatched CES al type l to bonding agent material 2 and vice versa to encourage the Transverse Anderson Localization phenomena.
An embodiment for visible electromagnetic energy relays exists for all of the above radially symmetrical or spiraled optical materials where the optical elements that are formed are sliced into thin cylinders, and may be aligned in an array, as implementations of a diffractive lens that allow for the appropriate steering of the rays of light as required for a specific optical configuration. rates perspective views of a repeating pattern 140 of twenty CESs with a thickness that may or may not be the same per sheet spiraled into an energy relay structure wherein there is an input wave angle and an output wave angle that is a result of one or more differing EP of each region of material, in accordance with one embodiment of the present disclosure.
In an embodiment for visible electromagnetic energy , 140 contains twenty tive indices applied with thicknesses that may or may not be the same per sheet spiraled into an optical relay structure that is able to steer an electromagnetic wave as a result of the differing refractive index of each region of material, in accordance with one embodiment ofthe present disclosure.
In an additional embodiment for visible electromagnetic energy relays, the refractive index of the material changes as a specific function of radius from the center of the spiral. In this n, it is possible to fabricate a plurality of sheets of material as identified previously with a sequence ofrefractive indices as designed for a specific optical function for steering rays of light through the optical relay element. This may additionally be placed into an array as previously disclosed or cut or polished or the like as discussed 'vvith other embodiments.
