迂回位相型计算全息图和修正离轴参考光计算全息图的对比讨论

摘要

It got the detour phase hologram and Boqi hologram using the Matlab language, and got reconstructed image by Fourier transformation. The characteristics of two computing holograms were elaborated, and the quality, quantity, size, program running speed of the reconstructed image were made a comparison. Computing hologram with Detour phase is easy to record and convenient delivery. Boqi coding are used to get the modified off-axis reference beam as computing hologram has a high quality reconstructed image,and com-puting speed is faster. The complex two-dimensional images which can consider using this encoding method to calculate the holographic.%使用Matlab语言得到了迂回位相全息图和博奇型全息图，由傅里叶逆变换得到再现像。阐述了两种计算全息图各自的特点，对再现像的质量、数量、大小、程序运行速度作出对比讨论。迂回位相计算全息图有便于记录、方便传递的特点。利用博奇编码得到的修正离轴参考光计算全息图有高质量的再现像，而且计算速度也比较快，对于复杂的二维图像，可以考虑利用这种编码方法进行计算全息。
