Study of a Telescope System Based on Holographic Optical Elements

In this paper, a telescope system based on holographic optical elements (HOEs) is developed and used for 3D object imaging experiments. First, the principle and fabrication method of HOE are introduced, and the optimal parameters for HOE recording are obtained through test experiments. Then, the HOE telescope system was constructed for experimental demonstration, and the degree of diffraction reproduction image reconstruction was evaluated by calculating the structural similarity. The experimental results show that the holographic optical telescope system can realize good imaging effect and different magnification effects by replacing HOEs with different focal lengths, and the holographic optical telescope system can flexibly adjust the telescopic magnification compared with traditional telescopes.
