Dynamic Behavior of Azobenzene Polyester Used for Holographic Data Storage.

摘要

Dynamic behavior of thin photoaddressable polyester films was studied. The saturation process due to Fourier holographic recording was investigated. Model experiments show an optimal intensity ratio of the object and reference beams, where the highest efficiency occurs. This ratio is inversely proportional to the reference intensity. The material has a significantly higher sensitivity at 407 nm than at 532 nm. For 1 micrometers thick sample an M(pound sign) of 0.25 was measurable.
