This paper presents a method based on the use of an image sensor for obtaining the complex amplitudes of beams diffracted from an object at two different wavelengths. The complex amplitude for each wavelength is extracted by the Doppler phase-shifting method. The principle underlying the proposed method is experimentally verified by using the method with two lasers having different wavelengths to measure the surface shape of a concave mirror.
本文提出了一种基于使用图像传感器的方法，用于获取物体在两个不同波长下衍射光束的复振幅。每个波长的复振幅通过多普勒相移法提取。通过使用具有不同波长的两台激光器的方法来测量凹面镜的表面形状，对所提出方法的原理进行了实验验证。
