Abstract

Reduction of imaging (associative) properties of a reference- less hologram as the registration plane moves to far-field re- gion (i.e., as the wave parameter approaches unity) is Ã¢â‚¬Â¢conside- red. It is shown, that anomal intensity decreasing at the ghost image in the nearest vicinity of the readout part of an object as well as reduction of signal-to-noise ratio at associative reconstructions are explaned with account of the filtering ac- tion of a free space and intrinsic scale of an object field, rather than from aperture limitation that is the main factor of image degradation figuring into conventional telescopic imaging or ofit-axis holography.
