多层层积光导层的高感光度光导热塑全息片的研制

Study of high sensitivity photoconductive thermoplastic holographic lamina with multilayer stacked photo-conductive layer

本文在SPT-Ⅱ型光导热塑全息片研制的基础上,采用多层层积光导层的方法,以亚层结构产生一定功能分离的作用,强化记录介质的光电导性能,增大全息记录时的电荷反差,从而较大辐度地提高了感光灵敏度和变形深度。

This paper are based on the reseach of SPT-type Ⅱ photoconductive thermo plastic lamina by stratifying a Photoconductive layer on photoconductive therm plastic lamina, in order to results the function of partly seperation by the infralayer structure, which improves the photoelectric sensitivity of recording media and makes the charge distribution strong during holographic recording and largly enhancement of sensitivity for light intensity and transform deep.
