Abstract

A high intelligence optical fiber image sensor consisting of the optical fiber image transmission bundle, camera, and microcomputer is described. Its principle is that an image of the object in a particular environment is formed by the optical objective at one end of the optical fiber image transmission bundle and transmitted by the optical fibers. The two- dimensional optical image at the other end is converted by the camera into video signals which are loaded onto the A/D board in the microcomputer to realize A/D conversion. the resulting digitalized image is stored in the frame memory. Image processing and analysis such as noise elimination, image intensification, detection, identification and counting are performed on this image by the programmed dedicated software. This device enables picture pick-up and processing in places with strong magnetic fields, radioactivity, high temperature, and high humidity as well as in areas classified as explosion-proof, featuring a good practicability.
