Temporal Filtering Properties of Holograms

Abstract

A hologram may be regarded as a linear temporal filter operating on the time-varying object fields incident during exposure. Such a point of view allows the effects of object vibrations and other simple motions to be predicted in a straightforward fashion. In addition, this filtering property suggests that holograms might be used to provide doppler maps of moving objects. Finally, the temporal-filtering viewpoint offers insight into the effect of the wavefront reconstruction process on images of noncoherent objects.
