An IR Twyman-Green interferometer is described. It uses a cw CO(2) laser as a light source operating at a 10.6-microm wavelength. Theoretical analysis and experimental measurements of the relationship between the contrast of the interference fringes

Workshop on Optical Fabrication and Testing.
Although computers have been used extensively for optical design and analysis, the use of computers to control optical fabrication has been limited to only a few applications. During the early 1970's computer controlled optical figuring machines were

Interferometry.
An interferogram analysis system has been developed that uses a standard television camera interfaced to a microcomputer to acquire the coordinates of fringe centers. Following single-frame capture at a resolution of 480 x 512 x 1, continuous lines a

Infrared interferometric systems using a CO2 laser operating at a wavelength of 10.6 μm are described. Specific systems discussed are a Twyman-Green interferometer and a Twyman-Green interferometer with an infrared computer-generated hologram (IRCGH

Interferometry.
The in situ testing of an unpolished off -axis parabolic mirror with a vertex radius of12.8 m, a diameter of 1.42 m, and an off -set of 1 m is described. Interferograms are shownthat were obtained during the fabrication process by means of a long- wa

A point-diffraction interferometer (PDI) for use in the infrared is discussed. It is shown that the PDI is simple and easy to use and also yields fringes of constant optical path difference similar to those obtained with a Twyman–Green interferomet
