We describe experimental studies of the recording of the relief of a diffusely reflecting surface using a shear interferometer. The interferometer uses a Michelson scheme, but the mirrors serve to combine two identical beams displaced with respect to each other. In this case, interference arises between the neighboring points having different phases. The interference pattern reflects the change in phase at each point. Two variants of the scheme were employed in the experiments: one scheme uses a magnifying lens near the sample and the other, a projection lens near the interferometer. The paper also presents the results of numerical simulation aimed at studying the ultimate capabilities of the method. A model part, on the surface of which four groups of geometric figures with different configurations were formed, was used as the test object. This allowed one to determine the limiting spatial resolution, the limiting displacement along the optical axis, the limiting angular sensitivity, and the possibility of finding the surface profile.

我们描述了使用剪切干涉仪记录漫反射表面浮雕的实验研究。干涉仪使用迈克尔逊方案，但反射镜用于组合两个相对于彼此位移的相同光束。在这种情况下，在具有不同相位的相邻点之间出现干扰。干涉图反映了每一点的相位变化。实验中采用了该方案的两种变体：一种方案在样品附近使用放大镜，另一种方案在干涉仪附近使用投影透镜。本文还介绍了旨在研究该方法的最终能力的数值模拟结果。以在其表面形成四组不同构型的几何图形的模型零件作为测试对象。
