title: Radial shearing interferometers using a laser source.
abstract: Radial shearing interferometers have been devised by several workers earlier. All of them were based on conventional light sources, and consequently full white light compensation was required. 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. Some of these arrangements are described in the present paper.
