线性三色采样叶形光栅的制作和应用

The Generation and Application of Linear Tricolor Sampling Leaf-Shape Grating

用新颖的线性三色采样叶形光栅，可以在单色胶片上一步记录彩色图像。这种记录和再现过程不仅操作方便，仪器简单、经济，而且避免了色串扰、莫尔（Moire）条纹与分辨率的损失，消除了互调制，大大提高了光能利用率。本文给出了用计算机制作叶形光栅的方法，讨论了用这种光栅编码彩色图像的原理及其在全息照相和光学信息处理等其它方面潜在的应用。

The application of a novel linear tricolor sampling leaf-shape grating to onestep in formation recording on a monochrome film is proposed. In this paper, it is proved that the proposed application can make the recording and retrieving simple and economical to implement, the color-cross-talk, Moire fringes and marginal loss in resolution avoided, the mutual modulation cleared up, the utilization ratio of light energy improved greatly.A method of computer generating the linear tricolor sampling leaf- shape grating is described, the principle of encoding color image using the leaf-shape grating is presented and the potential application to holography and optical information processing is also discussed.
