Zusammenfassung:	The implementation of a new type of phase-shifting, self-referencing interferometer that simultaneously achieves the phase shift and separation of heams with a stationary diffraction grating is described. The capabilities of stroboscopic interferometry are demonstrated with results from an experiment in which the rapidly varying surface deformations of a sonically activated pellicle mirror are measured in a time-sliced fashion at 50-microsec intervals.
