A STUDY ON TECHNOLOGICAL PRINCIPLE OF OPTICAL INFORMATION CODING AND DECODING IN SECREY WITH COMPOUND EYE LENS I.IMAGING CHARACTERISTIC OF COMPOUND EYE OF INSECT AND TECHNOLOGICAL PRINCIPLE OF CODING AND DECODING

本文根据光学并列型和光学重叠型两类昆虫复眼的屈光系统,具有分解和综合二维图像的光学特性,提出了一种新的用复眼透镜实现二维图像光学信息编码和译码的技术原理.利用复眼透镜和一个特制的随机抽样编码的掩模板,可将一幅有序的二维图像(或者文献、资料等)编码形成为一幅无序的,具有良好保密性能的分解编码像,而且,还能将此编码像反演综合再现出原始图像.它不仅实现了对二维图像信息的多通道并行处理,而且还具有传输量大、速度快、保密性强等优点.我们利用此种复眼透镜光学信息编、译码的技术原理,对二维图像的光学信息进行了分解编码记录及综合译码再现.

A new technological principle of optical information coding and decoding with compound eye lens was introduce in this paper,according to the optical characteristic and the ability of resolving and synthesizing two-dimension pattern of dioptric system of compound eyes including optical apposition eye and optical superposition eye.Using compound eye lens and a piece of mask plate which was made with random sampling coding, a coded image with randomly pattern and in secrecy was formed from a orderly two-dimesion pattern (or documents and data). Information processing of two-dimension pattern was realized not only in parall, but also with quick speed. The greatest advatage was its secrecy.Optical information of two-di-mention pattern was coded in resolution and decoded in synthesis using this technological principle.
