摘要

为了实现傅里叶频谱测量，提出利用非相干照明结合单像素探测实现窗口函数傅里叶变换的频谱测量方法。首先，采用四步相移条纹投影，导出单像素探测频谱重构与窗口函数傅里叶变换频谱的关系，然后对三种窗口函数包括圆孔函数、矩形孔函数和矩形透射光栅的频谱进行测量。结果显示，该方法可以实现窗口函数的傅里叶频谱测量，为傅里叶变换频谱提供一种新的光学测量方法。

Abstract:

In order to realize Fourier spectrum measurement, a spectrum measurement method of windowfunction Fourier transform using incoherent illumination and single pixel detection is proposed. First, therelationship between single pixel detection spectrum reconstruction and window function Fourier transform spectrum is derived by using four step phase-shift fringe projection. Then the spectrum of three windowfunctions ,including circular function , rectangular function and rectangular transmission grating , are measured.The results show that this method can realize the measurement of the Fourier spectrum of window functions andprovide a new optical measurement method for the Fourier transform spectrum.

Key words: computational imaging Fourier spectrum window function single pixel detection
