坐标变换在傅里叶计算全息中的应用
The Application of Coordinate Transformation in Fourier Computer Generated Holograms
摘要
提出在傅里叶计算全息中,只要对虚拟物的频谱进行简单的坐标变换,就可获得虚拟物再现像的旋转、切变和翻转,阐明了此种坐标变换的原理,给出了与理论相符合的实验结果。
Abstract
In this paper, we proposed that virtual images, which have rotation, shear and inversion, can be obtained by a simple coordinate transformation of the Fourier spectrum in the Fourier computer generated Hologram. We clarify the principle of this coordinate transformation. The experimental results are in excellent agreement with a theoretical analysis.
