Paper Abstract

A method of encoding eight objects simultaneously in a detour computer generated hologram(CGH) is proposed. In the method, we divide eight objects into two groups and multiple objects are encoded through synthesized spectrum. The simulation demonstrated the effectiveness of the method. In the reconstruction two groups of objects were reconstructed around the same diffraction order along x, y directions, respectively. The result showed that the method can improve the information capacity in a CGH efficiently.
