Real Time Diffraction Efficiency and the Anti-humidity Mechanism of NGD Holograms

<正> Jn this paper,a new holographic recording material,nongelatin dichromated holographic film (NGU).is reported.The NGD holograms exhibit stronger real time effect,higher diffraction efficiency,better humidity,stability,stronger surface relief modulation,etc.An experimental study of the influence of electron donors on real time diffraction efficiency (RTDE) of NGD holograms has been earned out,and the anti-humidity mechanism of holograms analysed based on the rracrochemical structure of chelate.The concept that the symmetry of chelate structure is essential for good humidity stability of holograms is suggested.Remarkable is the contrast between NGD and DCG.The latter is another member of dichromated light sensitive systems and used to be considered the best phase holographic recording material However,the holograms of DCG,if not sealed,would decay quickly after several hours at relatively high temperature and humidity
