Abstract: Makes use of fractional Fourier transform as center tool to get new computing methods of holograms and realizes the computer simulation holographic generation and digital reconstruction,also introduces the spatial light modulators DMD and sets up a holography imaging system to complement the holography display.

Key words: holography display, fractional Fourier transform, DMD

摘要: 将分数傅里叶变换引入到全息图的计算中,提出一种分数傅立叶变换产生计算全息图的方法,并利用拆卸的投影装置搭建出以空间光调制器DMD为核心的全息显示光学系统并获得了分数傅里叶变换计算全息图在该系统下的全息显示效果及计算机模拟效果。
