Spatial Light Modulator (SLM) is an optically programmable element that can realize arbitrary light fields by changing the phase distribution. We are an industrialized company of Xi'an Institute of Optical Precision Machinery, Chinese Academy of Sciences, and have been engaged in SLM research and production for more than ten years. We have developed more than thirty SLM products with independent intellectual property rights relying on digital optical field modulation technology. Combined with its own optical load reliability technology and other advantages to develop ground simulation test equipment and color holographic and other modular experimental systems. They are widely used in projection imaging, structured light, computational holography, wavefront correction, beam control, etc.
