title: Incidental motion in interferometry of phase objects.
abstract: The effect of incidental motion of optical elements or of a phase object for interferometry of phase objects is examined. Estimates of maximum in-plane and out-of-plane displacements for speckle interferometry and holography interferometry are made. Measurements of fringe visibility are presented that give qualitative agreement with the estimates.
