Abstract

Abstract: In the current research on holography， CGH（Computer-Generated Hologram）， as for flexibility and ease of operation， has been discussed widely. However， there is not any ideal method for CGH and reconstruction of 3-D scene. This paper analyzes two methods to simulate the diffraction field， proposes a CGH method for 3-D scene， and accelerates the speed with the parallel computing technology. Taking the scene with four different depths as an example， the simulation results show that the algorithm is effective and feasible and the parallel computing technology accelerates the speed for four times.

Key words: computer-generated hologram, Fresnel diffraction, reconstruction, integral calculation, parallel computing
