Color Holographic Projection System Based On Spatial Light Modulator

System Functions:

1. Realize the import of color target image set;

2. Simulate the calculation of color holographic phase maps and reconstruction maps;

3. The internal algorithm of the software has integrated aberration calibration to calibrate the color difference in the system;

4. Compatible with image playback function, which can realize dynamic display;

5. Playback rate can be set and save the phase image.

    Product Briefing

    The system consists of color holographic coding software and color optical projection system. The software adopts the holographic coding method to generate holograms and load them onto the spatial light modulator (SLM), the SLM synchronously controls the R, G and B light waves of the tricolor laser and the timing of the SLM, and the display of color holographic information is realized through the visual transient effect of the human eye.

    Software function

    The control system software consists of two interfaces, the initialization interface and the calculation interface, in which the initialization interface is used to introduce the company and the principle of the color holography module; the calculation interface is mainly used for color holography calculations and contains two major functional modules, namely, holography calculations and image playback, the holography calculations are mainly used to realize the calculations of a single or a series of color hologramsets and load the corresponding images in the SLM, and at the same time, the holograms obtained by calculations can be loaded in the SLM. The hologram calculation is mainly used to calculate single or series of color holograms and load the corresponding images into SLM, meanwhile, the calculated holograms can be saved to the system folder; the image playback is mainly used to playback the image sets to realize the dynamic display effect, and different playback modes can be set.

    Holographic Virtual Image Viewing System

    By loading a hologram on a spatial light modulator, the phase modulation occurs after laser irradiation, and the reproduced image is obtained after a lens Fourier transform. In addition to receiving a real image, a holographic reproduction of an imaginary image can be observed by the human eye through the liquid crystal light valve surface or by using BS.
