Holography in a Spatially Inhomogeneous Medium

摘要

A Huygens-Fresnel principle, extended to a medium which exhibits a spatial variation in the index of refraction, is used to calculate the resulting fringe patterns in the Fresnel-Fraunhofer and point reference Fourier-Transform methods of holography. In particular, the resolution limits pertaining to these two methods are derived. Numerical results pertaining to underwater holography are given. (Author)
