In order to produce realistic target background images needed in the guided weapon simulation system, a visible light optical target simulator based on liquid crystal display of silicon is established. The actual renderings of simulator image output and the test methods and data of optical parameters are given. The test shows that the device has good brightness, contrast and uniformity, and effectively reduces the image flicker problem compared with the traditional cathode ray tube display technology, and can provide a stable video output, which is more favorable to the dynamic target in the simulation system Recognition, is a more ideal image simulation device. At the same time, the calculation method of the initial structure of the double-fold optical system is given and a simple calculation formula is deduced. The algorithm can be applied to other double-fold optical systems.
