红敏光致聚合物全息干板的特点及其使用方法

RSP—Ⅰ型红敏光致聚合物是一种新型全息记录介质,它完全由国产化学试剂配制而成。它对氦氖激光λ=632.8nm的红光敏感。感光灵敏度为1mJ/cm~2,衍射效率>80%。分辨率>4000cy/mm。在室温环境下可保存半年以上。可在日光灯下拍摄全息图。所摄反射型体积全息图图像清晰、明亮,可与重铬酸盐明胶版媲美。

The features and applications of red—sensitive photopolymer holographic dry plate

RSP- Ⅰ type red-sensitive photopolymer plate is a new holographic recording medium. It is disposed by chemical reagents that all are made in China. It is sensitive to redlight of He—Ne laser with the wavelength A=632.8nm. The sensitivity is 1mJ/cm~2, diffraction dffeciency is higher than 80% and the resolution is higher than 4000 cy/mm. It can be save in more than half year at room temperature. Using it, we can take hologram under a fluorescent lamp. The image of reflectance volume hologram taken is clear, bright and can be campared favouably with that of dichromate gelatia plate.
