Holographic interferometers for optical testing
TLDR
Holographically made components can be used in two types of interferometers: lateral shear and radial shear instruments as discussed by the authors, and they have been shown to have advantages which may extend their use.Abstract:
Holographically made components can be used in two types of interferometer: lateral shear and radial shear instruments. The principles, construction, and performance of these are described and examples of interferograms given. The holographic interferometers are shown to have advantages which may extend their use.read more

Compact in-line laser radial shear interferometer.
TL;DR: A compact in-line radial shearing interferometer using laser as a light source and some applications for testing lenses and infrared optical systems and for accessing the quality of an emerging wave front from the exit slit of a monochromator are suggested.

Increase in the sensitivity of holographic reversible shearing interferometry by turning around an object
I A Lyavshuk,A M Lyalikov +1 more
TL;DR: In this paper, it was shown that a turn of an object in holographic reversible shearing interferometry in the case of objects with linear dimensions not exceeding half the diameter of a probe light beam allows the doubling of the sensitivity of interferograms mapping changes in a wavefront caused by the object.

Double Frequency Grating Lateral Shear Interferometer
TL;DR: A simple grating lateral shear interferometer is described that can be made to give simultaneously two interferograms having shear in two orthogonal directions to be used with real-time heterodyne phase detection.

Shearing Interferometry with Constant Radial Displacement
TL;DR: In this article, a constant shear is introduced in the radial direction for small shear and the interferogram displays the radial phase derivative of the wave front under test, which can be realized with axicon or circular grating arrangements and seems useful for objects with cylindrical or circular geometry.

Radial shearing interferometers using a laser source.
M. V. R. K. Murty,Rohit Shukla +1 more
TL;DR: It is possible to devise several schemes of radial shearing interferometers ignoring the condition of white light compensation when a laser source is used in place of a conventional source.

A Radial-shear Interferometer for Use with a Laser Source
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.
