1. A method of generating a computer-generated hologram (CGH), the method comprising:
obtaining complex data including amplitude data of object data and phase data of the object data corresponding to a spatial light modulator (SLM) plane by propagating the object data from an image plane to the SLM plane;
encoding the complex data into encoded amplitude data; and
generating a CGH based on the object data including the encoded amplitude data,
wherein the obtaining of the complex data further comprises propagating the object data and obtaining the complex data based on a neural network.
