THE FRAUNHOFER-FRESNEL HOLOGRAM AND ITS APPLICATIONS

A useful type of hologram, the Fraunhofer-Fresnel hologram (FFH), is p roposed and studied. Its potential for lensless optical information pr ocessing, multifacet holographic storage and programmable interconnect ion is experimentally demonstrated. Compared with previous methods, su ch as the conventional Fourier hologram and the newly suggested pinhol e hologram, the FFH has special advantages: high resolution, better re cording linearity, easy to house additional elements, and the simplest optical arrangement.
