摘要 对离轴参考光计算全息图的制作进行了研究.基于光学离轴参考光全息原理,对全息干涉场的空间频谱进行分析,得出了离轴参考光全息图的相关参数;用计算机分别模拟物光波和参考光波,设计全息图的相关参数,采用快速傅里叶变换算法,通过计算得到离轴参考光计算全息图;用激光再现获得全息再现像.形成用计算机制作离轴参考光全息图的理论与方法,并进行了实验验证. Based on the theory of optical off-axis holography, the spatial frequency spectrum of hologram was analyzed, and the relevant parameters of computer-generated off-axis hologram obtained. Then, simulating the interference process of optical hologram fabrication by computer, setting the parameters of computer- generated hologram, and using fast fourier transform algorithm, a computer-generated off-axis hologram was acquired and a holographic reconstructed image was observed when the computer-generated off-axis hologram was laser illuminated. The making of computer-generated off-axis hologram was thus formed and verified by experiments.
