Features of distribution of a brightness of deniskyuk's holograms

摘要

The method of hologram recording of Yuri.N.Denisyuk is remarkabel because of its simplicity and excellent quality of a holographic imagte. However, distribution of brightness of the reconstructed image, as a rule, is nonuniform. In the top of a zone of observation such image is brighter, than in the bottom. In this report is explained, that the reason of this effect is the polarization of a recording beam. Also the way of elimination of non- uniformity of distribution of brightness of the reconstructed image in a zone of observation is proposed.
