The Design And Application Of The Automatic Programming Software Of Computer-generated Hologram

With the rapid development of computer-generated hologram(CGH),the researchers in holographic field have been increasing their attention in the field of CGH.CGH simulation of traditional optical holography requires coding,for researchers who don't have any coding foundation for the initial CGH,learning to CGH requires a large time cost.In order to reduce the time cost,this study has written an automatic coding software to enable the researchers of the initial CGH to have a perceptual knowledge of the computational holography.This article first introduced the automatic coding software development history at home and abroad,describes the automatic coding software coding theory,and discusses the Huang coding,Kinoform coding,Fresnel transform CGH coding,coding is applied to the 3 d effect automation software.There are two jobs in this study.The first one is to encode the Huang code,the Kinoform code,and the Fresnel transform CGH encoding three coding functions into the automated coding software.In an image,the function of automation software is by calling the above three coding function can simultaneously output Huang CGH,Kinoform CGH,Fresnel transform CGH,and Huang CGH reconstruction figure,Kinoform CGH reconstruction figure,Fresnel transform CGH reconstruction figure.Different pixel images and different images can achieve the above six results by coding software.The second task of this study is to add three-dimensional effects to the production of holograms into automated software,where 2.5D can be used to CGH real-time display.Input different pixel image after automatic coding software,can output Huang coding CGH at the same time,the calculation of Kinoform figure hologram,Fresnel transform CGH,3 d effect CGH,and Huang CGH reconstruction figure,interest figure CGH reconstruction figure,Fresnel transform CGH,2.5D CGH and reconstruction results.
