TL;DR: A simple lateral shearing interferometer is devised using the Michelson interferometers as the basis, which consists of essentially two right angle prisms put together to have fixed shear.
Abstract: 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.

TL;DR: In this article, an interferometer that combines the design simplicity of a laser interferer and the insensitivity to vibration of a common-path instrument is described, which is used to test wave aberration in single passage.
Abstract: An interferometer is described that combines the design simplicity of a laser interferometer and the insensitivity to vibration of a common-path instrument. It is used to test wave aberration in ‘single passage’.

TL;DR: There exists an interferometer equivalent to every holographic process as mentioned in this paper, which can be used to reveal the possibilities and limitations of the holographic processes before they are used for any application.
Abstract: There exists in principle an interferometer equivalent to every holographic process. Consideration of this interferometer will often disclose the possibilities and limitations of the holographic process before it is used.

TL;DR: A relatively inexpensive, versatile interferometer has been developed to evaluate the combined surface and internal properties of long, highly doped laser rods.
Abstract: A relatively inexpensive, versatile interferometer has been developed to evaluate the combined surface and internal properties of long, highly doped laser rods. The basic interferometer configuration, which is a modified Mach-Zehnder type, can be used for Brewster-ended as well as for square-ended rods in the pumped or unpumped condition. An unusual feature of this interferometer is that both beam splitters and mirrors are located in the same arm rather than in opposite corners as found in the conventional M-Z interferometer. Some shadowgraph pictures and interferograms of laser rods obtained with the interferometer are shown.
