用单色激光彩虹全息图保存彩色图象

Storage of Color Films by Means of a Single wavelength Laser and Slm s

本文提出一种彩色图象存储的新方法。该方法用液晶空间光调制器实现不同颜色的非相干光到同一种波长相干光的转换，从而可以用单色激光彩虹全息图保存彩色图象，具有记录系统简单，成本低的特点。

In this paper, a new storage approach of color films by means of a single wavelength laser and SLM s is presented.The conversion from incoherent light of different colors to a single wavelength coherent light is realized with a CdS liquid crystal SLM.Therefore a color image can be stored in a rainbow hologram.This method is simple in construction and cheap in costs.
