Research on a fast algorithm of three-dimensional CGH

This paper puts forward a novel fast algorithm of three-dimensional Computer-Generated Hologram (CGH). The algorithm proposed can directly express the two-dimensional Fourier spectrum of a unit square by an analytic function, as well as the light field distribution of the unit square on the holographic plane (the unit square is not parallel to the holographic plane). The computer simulation and photoelectric reconstruction are also performed to verify the algorithm. The experimental results show that the algorithm is quick and simple, providing a good reference to research on three-dimensional CGH.
