Until now almost all the lateral shearing interferometers have been based on the Mach-Zehnder or Jamin interferometers. Many of these modifications are useful in optical testing, interference microscopy, etc. A simple lateral shearing interferometer is devised using the Michelson interferometer as the basis. This consists of essentially two right angle prisms put together. These prisms are cemented together to have fixed shear. Also, an interferometer of variable shear is built by having a thin layer of oil between the prisms. The interferometer is used in optical testing by placing it in the focal region of an optical system.
到目前为止，几乎所有的横向剪切干涉仪都是基于马赫-曾德尔干涉仪或雅满干涉仪。其中许多改进在光学测试、干涉显微镜等方面很有用。设计了一种以迈克尔逊干涉仪为基础的简单横向剪切干涉仪。它主要由两个拼接在一起的直角棱镜组成。这些棱镜胶合在一起以获得固定的剪切量。此外，通过在棱镜之间设置一层薄油膜构建了一种可变剪切量的干涉仪。将该干涉仪放置在光学系统的焦区用于光学测试。
