Abstract
A system for recording and reading out holograms in a storage medium including a pattern encoder, a first fourier transform lens with a focal length f , a second fourier transform lens with a focal length f , a detector array, and a first and second prism. The first prism is located between the pattern encoder and the first fourier transform lens, wherein the optical length between the pattern encoder and the first fourier transform lens through the first prism is equal to a back focal length BFL . The second prism located between the second fourier transform lens f and the detector array, wherein the optical path length between the second fourier transform lens and the detector array through the second prism is equal to a back focal length BFL .
