摘　　要：本文根据复眼透镜光学信息编译码的技术原理,实现了对二维图像进行分解编码记录以及综合译码再现.一幅m×n个目标单元的二维图像,通过1×k阵列的复眼透镜,得到(1×k)(m×n)个像元.经过一个特制的掩模板,得到一幅随机分解编码像,并根据透镜的物、像共轭原理,综合再现了原始图像.进而还实现了同时记录多幅二维图像信息的互补编码像,以及将互补编码像分离重现了每一幅原始目标图像.此互补编码像携带了更大的信息量,同时也大大提高了保密性能.According to technological principle of optical information coding and decoding of compound eye lens, recording resolved and coded image and reappearing synthesized and decoded original pattern were realized for two-dimension of pattern. As a (mxn) element two-dimension pattern passed through the compound eye lens which was made of (lxk) lens lets array, (mxn) (lxk) image elements could be formed in the image space. A coded image was formed by a piece of special coded mask plate. This coded image could reappear synthetically original pattern, using the conjugate between object and image. A mutual-complementing coded image of several two-dimension patterns was obtained, and each original pattern was reappared respectivly. The mutual-comptemeting coded image carried more information and would be more hard to decode by some one else.
