本文提出的光学结构由一个4-f光学系统和一个位于傅立叶平面上的波前调制装置组成，如凹面镜和空间光调制器。具有所提出的配置的重建图像的横向放大率与对象和图像传感器的位置无关;因此，可以用固定的横向放大率缩放不同距离处的对象的重建图像。它是基于傅里叶光学理论得到的，并用光学矩阵方法进行了数学验证。数值模拟结果和实验结果也证实了重建图像的固定性。(c)2018美国光学学会
The optical configuration proposed in this paper consists of a 4-f optical setup with the wavefront modulation device on the Fourier plane, such as a concave mirror and a spatial light modulator. The transverse magnification of reconstructed images with the proposed configuration is independent of locations of an object and an image sensor; therefore, reconstructed images of object(s) at different distances can be scaled with a fixed transverse magnification. It is yielded based on Fourier optics and mathematically verified with the optical matrix method. Numerical simulation results and experimental results are also given to confirm the fixity of the reconstructed images. (c) 2018 Optical Society of America
