Abstract

We describe an interferometer functioning in the region of 10 mm, developed for the examination of the homogeneity of IR materials and for the TWyman-Green testing of the wave surface of IR optical systems. This interferometer used a CO laser as source and a diffraction grating as separator. A scanning camera associated with a point detector reconstructs the interferogram on the screen of an oscilloscope. We also present a second -generation instrument recently produced in.collaboration with an industrial company as well as some typical applications of these interferameters,in evoking their possibilities of extension to the domain of common mechanics for the demonstration of the form of parts. We also present an experiment of linear reconstruction of the phase in order to directly obtain the wave surface, effected with the infrared interferometer, whose path difference is put to use.
