Abstract
A conventional radial-shear interferometer is converted to a multi-channel phase-shifted interferometric system. Simple diffraction gratings are used to obtain three 90 degree phase-shifted interferograms simultaneously in Mach-Zender type interferometer layout. Parallel acquisition and digital data processing of the three interferograms make it possible to measure wavefront phases from either pulsed or CW light sources. Basic principles of this new interferometer are discussed and also preliminary laboratory results are shown.
