- FIGS. 13A-13B illustrate aspects of a diffractive imaging module embodiment.
- FIGS. 3A and 3B various aspects of an AAD system are depicted.
- FIG. 3A a simple illustration shows that in the place of two conventional displays as in stereoscopy ( FIG. 2 ), two complex images, one for each eye, with various radial focal depths ( 12 ) for various aspects ( 14 ) of each image may be utilized to provide each eye with the perception of three dimensional depth layering within the perceived image.
- a near field limit ( 78 ) of about 0.25 meters is about the closest depth of focus; a far-field limit ( 80 ) of about 3 meters means that any item farther than about 3 meters from the human eye receives infinite focus.
- the layers of focus get more and more thin as one gets closer to the eye; in other words, the eye is able to perceive differences in focal distance that are quite small relatively close to the eye, and this effect dissipates as objects fall farther away from the eye, as shown in FIG. 3B .
- Element 82 illustrates that at an infinite object location, a depth of focus/dioptric spacing value is about 1 ⁇ 3 diopters.
- a depth of focus/dioptric spacing value is about 1 ⁇ 3 diopters.
- FIG. 3B One other way of describing the import of FIG. 3B : there are about twelve focal planes between the eye of the user and infinity. These focal planes, and the data within the depicted relationships, may be utilized to position virtual elements within an augmented reality scenario for a user's viewing, because the human eye is constantly sweeping around to utilize the focal planes to perceive depth.
- K(R) is a dynamic parameter for curvature equal to 1/R, where R is the focal radius of an item relative to a surface, then with increasing radius (R3, to R2, up to R1), you have decreasing K(R).
- the light field produced by a point has a spherical curvature, which is a function of how far away the point is from the eye of the user. This relationship may also be utilized for AAD systems.
- FIGS. 6A-6C illustrate that with decreased spacing ( 18 , 28 , 30 ) in the diffraction pattern ( 22 , 24 , 26 ), the angle ( 20 , 32 , 34 ) becomes greater.
- FIGS. 7A-7C three different focusing mechanisms are depicted—refraction through a lens ( 36 ), reflection with a curved mirror ( 38 ), and diffraction with a Fresnel zone plate ( 40 ), also shown in FIG. 7D ( 40 ).
- These images could be confusing to the human eye and brain, and particularly problematic if all focused on-axis, as shown in FIG. 8B .
- an off-axis focus configuration may be utilized to allow for blocking of modes/images that are unwanted.
- the difference in spatial location of these modes/images and their trajectories allows for filtering out or separation to prevent the aforementioned problems associated with diffraction imaging, such as overlaying, ghosting, and “multiple exposure” perception effects.
- a waveguide having an embedded diffraction grating; such waveguides are available, for example, from suppliers such as BAE Systems PLC of London, U.K. and may be utilized to intake an image from the left of FIG. 9 as shown, pass the image through the embedded diffraction grating ( 44 ), and pass the resultant image out at an angle (in FIG. 9 , for example, through the side of the waveguide).
- a dual use of redirection and diffraction may be achieved with such an element.
- off-axis focal techniques such as those described in reference to FIG. 8C , may be combined with diffraction waveguide elements such as that shown in FIG. 9 to result in a configuration such as that shown in FIG.
- FIGS. 11A-13C the aforementioned concepts are put into play with various augmented reality display configurations.
- an AAD system comprises an imaging module ( 46 , 48 ) in front of each eye ( 4 , 6 ) through which the user sees the world.
- FIG. 11B illustrates a larger view of the module ( 46 ) with its associated (coupled via the depicted electronic control leads; leads may also be wireless) controller ( 66 ), which may be a microprocessor, microcontroller, field programmable gate array (FPGA), application specific integrated circuit (ASIC), or the like.
- the controller preferably is coupled to a power supply and also an information exchange device, such as a wireless internet or Bluetooth adaptor, to allow for the exchange of information between the outside world and the controller ( 66 ).
- the system may be configured to operate at an image refresh rate, such as a rate between 30 and 60 frames per second.
- the controller may be configured to operate a high-refresh rate digital high resolution display ( 52 ), such as a ferro-liquid, bluephase, or bent-core display, to display various zone plate geometries quickly in succession, pertinent to each of the 12 or so depth layers.

- the zone plate display ( 52 ) may be operated at 12 times this, or 720 Hz, to be able to provide simulated accommodation to each of the 12 depth layers as shown in FIG. 3B .
- the occluding mask display ( 54 ) is configured to display a blacked out image geometrically corresponding to the image displayed before it on the transparent projector layer ( 56 )—blacked out to prevent light from the other side of the occluding mask display from bleeding through or interfering with display of a desired virtual or augmented image in the projector layer ( 56 ).

Description
- The present application is a continuation application of U.S. patent application Ser. No. 13/684,489 filed on Nov. 23, 2012, which claims the benefit under 35 U.S.C. §119 to U.S. Provisional Application Ser. No. 61/563,403 filed Nov. 23, 2011. The foregoing applications are hereby incorporated by reference into the present application in their entirety.
- The present invention relates to virtual reality and augmented reality imaging and visualization systems.
- In order for a 3D display to produce a true sensation of depth, and more specifically, a simulated sensation of surface depth, it is desirable for each point in the display's visual field to generate the accommodative response corresponding to its virtual depth. If the accommodative response to a display point does not correspond to the virtual depth of that point, as determined by the binocular depth cues of convergence and stereopsis, the human eye may experience an accommodation conflict, resulting in unstable imaging, harmful eye strain, headaches, and, in the absence of accommodation information, almost a complete lack of surface depth. Referring to
FIG. 1 , an augmented reality scenario (8) is depicted with views to the user of actual objects within the user's reality, such as landscaping items including a concrete stage object (1120) in a park setting, and also views of virtual objects added into the view to produce the “augmented” reality view; here a robot statue (1110) is shown virtually standing upon the stage object (1120), and a bee character (2) is shown flying in the airspace near the user's head. Preferably the augmented reality system is 3-D capable, in which case it provides the user with the perception that the statue (1110) is standing on the stage (1120), and that the bee character (2) is flying close to the user's head. This perception may be greatly enhanced by utilizing visual accommodation cues to the user's eye and brain that the virtual objects (2, 1110) have different depths of focus, and that the depth of focus or focal radii for the robot statue (1110) is approximately the same as that for the stage (1120). Conventional stereoscopic 3-D simulation display systems, such as that depicted inFIG. 2 , typically have two displays (74, 76), one for each eye, at a fixed radial focal distance (10). As stated above, this conventional technology misses many of the valuable cues utilized by the human eye and brain to detect and interpret depth in three dimensions, including the accommodation cue, which is associated with the eye's repositioning of the crystalline lens within the eye complex to reach a different depth of focus with the eye. There is a need for an accommodation accurate display system which takes into account the accommodation aspects of the human eye/brain image processing complex. - One embodiment is directed to a three-dimensional image visualization system, comprising a selectively transparent projection device for projecting an image toward an eye of a viewer from a projection device position in space relative to the eye of the viewer, the projection device being capable of assuming a substantially transparent state when no image is projected; an occlusion mask device coupled to the projection device and configured to selectively block light traveling toward the eye from one or more positions opposite of the projection device from the eye of the viewer in an occluding pattern correlated with the image projected by the projection device; and a zone plate diffraction patterning device interposed between the eye of the viewer and the projection device and configured to cause light from the projection device to pass through a diffraction pattern having a selectable geometry as it travels to the eye and enter the eye with a simulated focal distance from the eye based at least in part upon the selectable geometry of the diffraction pattern. The system further may comprise a controller operatively coupled to the projection device, occlusion mask device, and the zone plate diffraction patterning device and configured to coordinate projection of the image and associated occluding pattern, as well as interposition of the diffraction pattern at the selectable geometry. The controller may comprise a microprocessor. The projection device may comprise a substantially planar transparent digital display substantially occupying a display plane. The display plane may be oriented substantially perpendicularly from a visual axis of the eye of the viewer. The substantially planar transparent digital display may comprise a liquid crystal display. The substantially planar transparent digital display may comprise an organic light emitting diode display. The projection device may be configured to project the image toward the eye in a collimated form such that the depth of focus for the eye of the viewer is an infinite depth of focus. The projection device may comprise a high-speed mini-projector coupled to a substrate-guided delay exit pupil expander device configured to expand the size of the image before delivery to the eye of the viewer. The mini-projector may be mounted substantially perpendicularly to a visual axis of the eye of the viewer, and wherein the substrate-guided delay exit pupil expander device is configured to receive the image from the mini-projector and deliver it to the zone plate diffraction patterning device and to the eye of the viewer in the expanded size with an orientation substantially aligned with the visual axis of the eye. The zone plate diffraction patterning device and projection device may comprise at least one common structure. The zone plate diffraction patterning device may be integrated into a waveguide, such that the projection device comprises a high-speed mini-projector coupled to the waveguide and configured pass the image through the diffraction pattern before the image exits the waveguide en route to the eye of the viewer. The mini-projector may be mounted substantially perpendicularly to a visual axis of the eye of the viewer, and the waveguide may be configured to receive the image from the mini-projector and deliver it to the eye of the viewer in an expanded size with an orientation substantially aligned with the visual axis of the eye. The occlusion mask device my comprise a display configured to either occlude or pass light at each of a plurality of portions of the display, depending upon a pertinent command to occlude or pass light at each portion. The occlusion mask device may comprise one or more liquid crystal displays. The zone plate diffraction patterning device may comprise a high-frequency binary display configured to either occlude or pass light at each of a plurality of portions of the display, depending upon a pertinent command to occlude or pass light at each portion. The zone plate diffraction patterning device may have a refresh rate of between about 500 Hz and about 2,000 Hz. The zone plate diffraction patterning device may have a refresh rate of about 720 Hz. The controller may be configured to operate the projection device and occlusion mask device at between about 30 and about 60 frames per second, and to operate the zone plate diffraction patterning device to digitally display up to about 12 different diffraction patterns for each frame of the projection device and occlusion mask device. The projection device, occlusion mask device, and the zone plate diffraction patterning device collectively may comprise an imaging module for a single eye of the viewer, and the system further may comprise a second imaging module for another eye of the viewer.

FIGS. 3A and 3B , various aspects of an AAD system are depicted. Referring toFIG. 3A , a simple illustration shows that in the place of two conventional displays as in stereoscopy (FIG. 2 ), two complex images, one for each eye, with various radial focal depths (12) for various aspects (14) of each image may be utilized to provide each eye with the perception of three dimensional depth layering within the perceived image. - Referring to
FIG. 3B , we have determined that the typical human eye is able to interpret approximately 12 layers (layers L1-L12 inFIG. 3B-drawing element 16) of depth based upon radial distance. A near field limit (78) of about 0.25 meters is about the closest depth of focus; a far-field limit (80) of about 3 meters means that any item farther than about 3 meters from the human eye receives infinite focus. The layers of focus get more and more thin as one gets closer to the eye; in other words, the eye is able to perceive differences in focal distance that are quite small relatively close to the eye, and this effect dissipates as objects fall farther away from the eye, as shown inFIG. 3B .Element 82 illustrates that at an infinite object location, a depth of focus/dioptric spacing value is about ⅓ diopters. One other way of describing the import ofFIG. 3B : there are about twelve focal planes between the eye of the user and infinity. These focal planes, and the data within the depicted relationships, may be utilized to position virtual elements within an augmented reality scenario for a user's viewing, because the human eye is constantly sweeping around to utilize the focal planes to perceive depth. - Referring to
FIGS. 4A-4C , if K(R) is a dynamic parameter for curvature equal to 1/R, where R is the focal radius of an item relative to a surface, then with increasing radius (R3, to R2, up to R1), you have decreasing K(R). The light field produced by a point has a spherical curvature, which is a function of how far away the point is from the eye of the user. This relationship may also be utilized for AAD systems. - Referring to
FIG. 5 , a conventional diffraction grating (22) is shown, with light passing through the grating spacing (18) at an angle (theta −20) which is related to the diffraction order (n), spatial frequency, and K factor, which equals 1/d, using the following equation: d*sin(theta)=n*wavelength (or alternatively substituting the K factor, sin(theta)=n*wavelength*K.FIGS. 6A-6C illustrate that with decreased spacing (18, 28, 30) in the diffraction pattern (22, 24, 26), the angle (20, 32, 34) becomes greater. - Referring to
FIGS. 7A-7C , three different focusing mechanisms are depicted—refraction through a lens (36), reflection with a curved mirror (38), and diffraction with a Fresnel zone plate (40), also shown inFIG. 7D (40). - Referring to
FIG. 8A , a simplified version of diffraction is shown to illustrate that an N=−1 mode could correspond to a virtual image; an N=+1 mode could correspond to a real image, and an N=0 mode could correspond to a focused-at-infinity image. These images could be confusing to the human eye and brain, and particularly problematic if all focused on-axis, as shown inFIG. 8B . Referring toFIG. 8C , an off-axis focus configuration may be utilized to allow for blocking of modes/images that are unwanted. For example, a collimated (r=infinity) image may be formed by the N=0 mode; a divergent virtual image may be formed by the N=−1 mode; and a convergent image may be formed by the N=+1 mode. The difference in spatial location of these modes/images and their trajectories allows for filtering out or separation to prevent the aforementioned problems associated with diffraction imaging, such as overlaying, ghosting, and “multiple exposure” perception effects. - Referring to
FIG. 9 , a waveguide is shown having an embedded diffraction grating; such waveguides are available, for example, from suppliers such as BAE Systems PLC of London, U.K. and may be utilized to intake an image from the left ofFIG. 9 as shown, pass the image through the embedded diffraction grating (44), and pass the resultant image out at an angle (inFIG. 9 , for example, through the side of the waveguide). Thus a dual use of redirection and diffraction may be achieved with such an element. Indeed, off-axis focal techniques, such as those described in reference toFIG. 8C , may be combined with diffraction waveguide elements such as that shown inFIG. 9 to result in a configuration such as that shown inFIG. 10 , wherein not only are redirection and diffraction accomplished, but also filtering, since in the depicted embodiment the geometry of the diffracting waveguide is such that the N=−1 mode (say the virtual image) is passed out of the waveguide and into the eye of the user, and the other two modes (N=0 and N=+1) are trapped inside of the waveguide by reflection. - Referring to
FIGS. 11A-13C , the aforementioned concepts are put into play with various augmented reality display configurations. - Referring to
FIG. 11A , an AAD system comprises an imaging module (46, 48) in front of each eye (4, 6) through which the user sees the world.FIG. 11B illustrates a larger view of the module (46) with its associated (coupled via the depicted electronic control leads; leads may also be wireless) controller (66), which may be a microprocessor, microcontroller, field programmable gate array (FPGA), application specific integrated circuit (ASIC), or the like. The controller preferably is coupled to a power supply and also an information exchange device, such as a wireless internet or Bluetooth adaptor, to allow for the exchange of information between the outside world and the controller (66). The system may be configured to operate at an image refresh rate, such as a rate between 30 and 60 frames per second. The controller may be configured to operate a high-refresh rate digital high resolution display (52), such as a ferro-liquid, bluephase, or bent-core display, to display various zone plate geometries quickly in succession, pertinent to each of the 12 or so depth layers. For example, in an embodiment wherein 60 frames per second overall performance is desired, the zone plate display (52) may be operated at 12 times this, or 720 Hz, to be able to provide simulated accommodation to each of the 12 depth layers as shown inFIG. 3B . The occluding mask display (54) is configured to display a blacked out image geometrically corresponding to the image displayed before it on the transparent projector layer (56)—blacked out to prevent light from the other side of the occluding mask display from bleeding through or interfering with display of a desired virtual or augmented image in the projector layer (56). Thus in an augmented reality configuration, as shown, light from the real background passes through the non-masked portions of the occlusion mask (54), though the transparent (i.e., not broadcasting a portion of an image) portions of the transparent projector layer (56), and into the zone plate layer (52) for accommodation treatment; images projected at the projecting layer (56) receive mask blocking from background light at the occlusion layer (54) and are projected forward into the zone plate layer (52) for accommodation treatment. The combination of these, or the associated perception of the augmented reality to the user, is very close to “true 3-D”. -
FIGS. 12A-12B depict another embodiment wherein an imaging module (58) comprises high-resolution mini projector oriented at an angle approximately perpendicular to the visual axis of the eye; a waveguide comprising a substrate guided delay exit pupil expander device (70) magnifies and redirects the image from the small mini projector and into the zone plate layer (52); the occluding layer (54) provides similar masking functions to protect perception of the projected images from background lighting. -
