Abstract

A general recording model of off-axis holography is first proposed, which includes three illumination modes: divergent, convergent and collimated beam illuminations. The interference pattern is then derived based on the general recording model. The general solutions on the recordable depth of view (RDV) and allowable farthest far-field distance (AFFD) are given analytically, which show that the RDV and AFFD may be improved by using non-collimated beam illumination and placing particle fields into a special spatial zone.
