Description
Technical Field
The invention relates to the field of application of spatial light modulators, in particular to a light field regulation and control system and a design method thereof.
Background
The spatial light modulator is a device for programmable regulation of light field, and obtains brand new read-out light field distribution by changing the amplitude, phase and polarization properties of the write-in light beam in spatial distribution, so that the spatial light modulator is widely applied to scientific research and industrial equipment, and is a scientific research tool and device which utilize the knowledge and the exploration to be unknown.
As shown in fig. 1, the way of programmably modulating the light field is that 100 users generate 102 an addressing data matrix through 101 light field modulation software, and obtain a data matrix of Array ═ P (m, n, d) with reference to 103 spatial light modulator resolution parameters, where m, n are spatial light modulator resolutions, d is data depth, P is a control Pattern function, Pattern is mapped to spatial light modulator addressing, and further modulate 104 a write beam to read a specific 105 read beam. In application, 100 users are divided into two categories: the method aims at discovering new Pattern and deeply researching various characteristics of 105 read light by researching the composition and definition mode of a light field P function, and generally uses computing software such as Matlab and the like to generate an addressing data matrix; the other type is that the existing research results are expected to be utilized to develop new research or development products, and the light field Pattern algorithm is not studied and is expected to be directly used. For the first class of users, there are countless possibilities for the composition of P-functions, and users can program themselves to define P-functions as required, and a flexible visualization tool is desired to generate the addressing data matrix, but self-programming is still the main means. The second category of users hope to have the existing light field regulation software, and avoid self programming as much as possible. Although there are some mature software with well-defined P function sets in the market, the change pattern is relatively rigid, and the contained contents are relatively scattered and lack systematicness, and lack effective and flexible coping means for uncertainty of the light path environment where the spatial light modulator is located.
The light field regulation is a relatively new research field, and besides the light fields which are verified by successively issued papers, a plurality of light fields with unknown and uncertain parameters still need to be researched and utilized. For spatial light modulator users, a set of software which can be quickly connected with a novel light field regulation and control technology function set and can also be designed to generate a new light field function can be designed, and the programming workload can be greatly reduced. In reality, because the design of the light field Pattern is unknown, the exploratory research cannot know in advance what Pattern should be used to regulate and control the desired light field, and therefore, the general Pattern design tool for light field regulation is either a generalized programming tool such as Matlab or a programming development platform, or a pure drawing tool, which is very heavy in workload and very poor in reusability.
However, in the prior art, since software cannot provide an unknown exploration mode with sufficient flexibility, especially for the transverse application of special light beams, such as the application of light fields in the non-optical research fields of materials science, biology and the like, software cannot generate exploratory unknown light fields in a series of regular paths based on known light fields, which greatly increases the technical threshold of users and reduces the working efficiency.

In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Specifically, the design method based on the light field regulation and control system comprises the following steps:
(a) aggregating the generating functions of the known light field;
(b) and combining the light field regulation and control basic units by utilizing a core design module.
Preferably, the step (a) further comprises the steps of:

Preferably, the step (b) further comprises the steps of:
(b0) the core design module comprises a basic function unit integrated module, a spatial superposition function module and a function superposition function module, and all the basic function unit integrated module, the spatial superposition function module and the function superposition function module are used for setting parameters of the spatial light modulator;

(b3) and the functional superposition function module receives the light field generated by the spatial superposition function module in the spatial dimension to perform secondary generation.
Preferably, the method further comprises the following step (c): and superposing the external environment function on the basis of the design result of the superposition function.
As shown in fig. 2, in the design method, the light field regulation system includes three parts, namely an external environment configuration module 201, a core design module 202 and an output addressing data matrix module 203.
The external environment configuration module 201 is a basic module, and does not change the functional definition of pattern (light field pattern) itself, and only configures the initialization parameters of the spatial light modulator, such as resolution, pixel size, etc., or configures the parameters of the light path environment, such as the wavelength of the used light beam, the relative relationship between the central position of the light beam and the spatial light modulator, the aberration of the light beam itself, or the Gamma curve, and the substrate error, etc., to compensate or correct. Module 201 is part of the ease of use of the present invention.
The core design module 202 further includes a basic function unit integration module, a spatial superposition function module, and a functional superposition function module. The basic function unit integrated module is used for carrying out unified visual generation on dozens of light field patterns with known characteristics, a human-computer interaction interface and a time dimension module are used as inlets, a user can change the set parameters of each Pattern and the transformation mode in the time dimension conveniently through a visual operation interface, and the patterns are automatically and dynamically generated through timing triggering. The basic function unit set comprises dozens of known light field regulation Pattern generating functions such as a vortex light beam function, a non-diffraction light beam function, a light beam shaping function, a basic grating function, a vector light beam function, a basic DOE simulation and the like. The invention carries out system combination, utilizes a uniform interface to configure and manage, and provides an interface for a user to submit externally designed Pattern into software for collection and management.
Further, the spatial stacking function module of the core design module 202 is further divided into an XYZ spatial coordinate system stacking function module and a polar coordinate system stacking function module. That is, the light field regulation and control in the basic functional unit integrated module is secondarily generated according to the superposition function template in the space dimension and the functional dimension, so that a new pattern distribution is obtained. The meaning and operation flow of such template functions are described in fig. 3 and 4 by way of example.
Specifically, as shown in fig. 3, the spatial superposition function in the XYZ coordinate system is multiplexed spatially by using a template function based on a basic function unit Pattern, the type of the template function includes the same array splicing, symmetric splicing, region area size splicing according to a function, and the like, and the type and the adjustable parameter content of the template function are predictively generated according to the light field theory. What is meant by predictive generation is that the Pattern finally generated by the template function may not have practical significance, and scientific research targets can be achieved under certain specific spatial light modulator models and external environment parameters. The starting point of the design is to provide a method for designing Pattern, rather than paying attention to the final characteristics of the light field generated by Pattern, which is the inventive significance of the invention, and is to encourage scientific researchers to explore unknown by experiments and simulation analysis.
As the template function in the spatial superposition function has infinite possibility, the core idea of the method is to divide the spatially distributed template function into a guide function and a region variation function. The guiding function is the position change guiding function of the Pattern area no matter what coordinate system; the region change is a region size change function, and the two functions are superposed with the change mode of Pattern itself to form a series of new light field regulation patterns. For example, the guidance function of the embodiment includes fibonacci number series, golden spiral, symmetric multiplexing, bisection multiplexing, power function multiplexing, quadratic curve multiplexing, and typing function multiplexing, and the region variation function includes a linear function, a polynomial function, a power function, a cosine function, a random function, and the like.
As shown in fig. 5, the Pattern to be multiplexed and superimposed includes a vortex beam function, a dammann grating function, an axial cone function, a vector function, a binary phase function, a fresnel lens function, an aperture function, a polygon function, and the like.
Several embodiments are presented in the present invention, in the effective optical area of the spatial light modulator, P (1) P (2) P (3) P (4) represents different parameters of the same Pattern at different spatial distribution positions; p1, P2, P3 and P4 represent different patterns when different spatial distribution positions are adopted. P001 is Pattern generated by spatially bisecting the spiral phase distribution as a multiplexing function. Fig. 3 illustrates design cases of different guide functions and area variation functions in an XYZ coordinate system, and fig. 4 illustrates a design case in a polar coordinate system.
In the Pattern result designed based on the method, part of the light field mathematical model and simulation result under specific parameters are verified by scientific researchers, and are actively popularized to an interferometric application scene, and part of the light field mathematical model and simulation result is still in an exploration research, so that more application scenes are expected to be found. Typical examples of such applications are photonic sieve designs or mask designs.
The present invention further shows a second embodiment, in which fig. 6 shows a sample obtained by superimposing the zernike aberration of the external environment function on the basis of the design result of the spatial superimposition function. The functional design is a compensation function introduced by light path elements or environmental factors in an application scene of the spatial light modulator, and the problem of adaptive matching of a theoretical model and environmental parameters in light field regulation is solved. This embodiment is completed based on the software design method proposed by the present invention.
The present invention further illustrates a third embodiment, in which fig. 7 specifically describes a specific implementation process of the human-computer interaction interface in the implementation process of the present invention. U001 is a guide function mode, can be selected through an interface and is represented as a pentagram space distribution function; the boot function is usually preset as a template in software, U002 is a size change anchor point, and U003 is an angle change anchor point, and can be activated by a mouse to be an operation hot spot dragging change. U004 selects the shape and size of a Pattern region, the embodiment is a circular entity region, and a region transformation function is also a template function and is preset in software; u005 is the Pattern result after completing the initial design, the content of the Pattern itself can be selected from the light field regulation and control basic function unit set, and the embodiment represents the Pattern with different transmittances by colors. U006 shows the interface layout mode and configuration parameter content of the embodiment. The embodiment shown in fig. 7 is very mature in software technology, and there are many specific ways of human-computer interaction interfaces following the method of the present invention, and the present invention describes a specific implementation manner of spatial superposition functions in light field regulation software in this embodiment.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
