摘要
本文提出一种基于Photoshop技术的假彩色编码片制作新方法。用Photoshop软件绘制不同方向的光栅图案,并将光栅图案填充到原始图片中,得到数字形式的多维光栅编码片;搭建数字图像缩微输出系统,将数字编码片分割成若干子编码片,通过光电缩微成像与拼接技术,实现假彩色编码片的高分辨率缩微输出;给出了制作方法与实验结果。
A new method of making pseudo-color coding photograph based on Photoshop technology is proposed. Firstly, digital gratings of different angles, which are drew using Photoshop, are filled in the different part of original image according to the gray level distribution, and a digital coding photograph composed of multi-dimensional gratings is obtained. Then, microcopy system of digital images is set up, the digital coding photograph divided into many small coding photographs is displayed on liquid crystal spatial light modulator and is recorded on holographic plate by the technique of microcopy imaging and image stitching, and a coding photograph is achieved. The principle and experiment result are given.
