摘要
根据光栅在傅里叶光学系统中的衍射特性,获得物体的傅里叶谱的实部和虚部信息,进而测出其傅里叶谱的实部和虚部信息,进而测出其傅里叶位相分布.本文给出了一维实物体的傅里叶位相的实验探测结果,并给予讨论.
On the basis of diffraction property of a grating in the Fourier optical system, the real part and imaginary part in the Fourier spectrum of object could be obtained, and the Fourier phase could be measured. The experimental results regarding to the optical measurement of Fourier phase for 1-D real object are presented and discussed in this paper.
