Summary:A method and system for processing a computer generated hologram (CGH) is disclosed. The system for processing the CGH comprises a CGH generation device and a display device. The CGH generation device repeatedly performs the following operations: propagating object data from a first depth layer to a second depth layer; changing amplitude data of the object data to second predetermined amplitude data; reversely propagating the object data from the second depth layer to the first depth layer; changing the amplitude data of the object data to first predetermined amplitude value data, and generating the CGH by using the object data. 公开了一种用于处理计算机生成的全息图(CGH)的方法和系统。用于处理CGH的系统包括CGH生成装置和显示装置。所述CGH生成装置重复地执行将对象数据从第一深度层传播到第二深度层，将所述对象数据的振幅数据改变为第二预定振幅数据，将所述对象数据从所述第二深度层反向传播到所述第一深度层，将所述对象数据的所述振幅数据改变为第一预定振幅值数据，并且通过使用对象数据生成CGH。
