二维彩色彩虹像面全息图记录的一种新方法

A new method for recording colour rainbow image plane hologram

本文提出了利用液晶光阀和单色激光进行彩色全息图记录的方法.借助于液晶光阀非相干-相干转换的功能,采用新的彩虹全息术,获得了记录于同一块干版上的原彩色目标由红、绿、篮三色所成的三个基色彩虹全息像.用白光透射再现,得到原彩色图的真彩色全息像.这种方法是液晶光阀、条形散斑屏在图像处理中的一种特殊应用.

A new method for recording colour hologram is proposed is this paper. Using liquid crystal ligh valve (LCLV) and a monohromatio laser. LOLV is a device with which incohernt light image can be translated into coherent light image. Three holograms corresponding to, three primary colour are recorded respectively on the same ailTer holide plate using a laser of 6328 A This hologram can reconstruote original colour image using whste light.
