Paper Abstract

Analysis has been made of the effect of the recording process parameters on formation dynamics and microstructure of relief-phase holograms recorded on photothermoplastic media by using IR radiation of a YAG:Nd3+-laser. Conditions has been found under which there occurs the effect of positive feedback with microrelief development process which leads to the `self-enhancement' of the relief- phase holograms. It is found that by proper selection of the development unit scheme and laser irradiation conditions the expansion of the effective spatial frequency band of about 150 - 200 mm-1 can be achieved.
