分数傅立叶变换(FrFT)在物体的横向位移和倾斜测量中的应用

Measuring transverse displacement and titling of object by using the fractional Fourier transformation

分数傅立叶变换是光学信息处理中的较新的分支,而得到广泛的关注。本文利用其变换的特性,综合利用分数傅立叶变换和常规傅立叶变换,提出同时测量物体横向位移和测量的方法,并给出了实验的结果。

The fractional Fourier transformation (FrFT) is shown to be of potential use in the optical information process. We derived a method to acquire the information of both transverse and tilting motion at one time to form the property of the FRTwhile. We showed the experiment setup and results.
