Research on three-dimensional computer-generated holographic algorithm based on conformal geometry theory

A novel method of three-dimensional computer-generated holographic algorithm based on conformal geometry theory was introduced. Firstly, three-dimensional object is transformed to a corresponding two-dimensional image via conformal transformation by making use of conformal geometry theory in mathematics, and then the Fresnel computer-generated hologram of the two-dimensional image is produced. During the reconstruction process, the three-dimensional reconstruction image of the original object is obtained by means of conformal coordinate transformation. The research results show that the algorithm introduced in this paper is characterized by fast running speed and good effects, providing a good reference for the research on three-dimensional computer-generated holographic algorithm.
