Paper Abstract

The method of spatial carrier synchronous detection of an interferogram, also called direct interferometry, has been developed by several authors. Besides reviewing this method, we present here two spatial carrier interferometric procedures using a spatial circular carrier and also a phase modulated carrier to compensate the aberration of aspherical surfaces.
