Abstract
A modified Michelson interferometer is described by which three, by - pi/2, 0 and + pi/2 phase-shifted interferograms can be taken simultaneously by a single CCD camera using a binary diffraction grating and polarization opti cs. Hence measurements of dynamic events and in adverse conditions are poss ible. The experimental setup, first results and a mathematical error analys is are presented.
