Optical fiber image sensor is to use image transmission beam. Image transmission beam composed of glass fiber arranged according to certain rules. Like in a beam, the article contains tens of thousands or even hundreds of thousands of article 10 ~ 20 microns diameter of fiber, every piece of optical fiber transmission a pixel information. Use as beam for image transmission, decomposition, synthesis and modification. Pass like a beam of optical fiber image sensor in the medical, industrial and military departments has been widely used.
(1) industrial endoscope
In the process of industrial production, often need to check the internal structure of system, and this kind of structure for various reasons can not open or close observation. Using optic fiber image sensors will probe into the internal system, through the transmission beam, can again system internal external observation, monitoring system, one of the structure by the objective lens, preach like beam, beam, the eyepiece. Light source the light through the beam to the object to be tested, lighting field, through the transfer and spread like a beam of the internal structure of the objective image, in order to observe and photograph. Another kind of structure is the internal structure of the image to CCD device, by pass like a beam which can converts light signals into electrical signals, and sent to the microcomputer for processing, and can be output by PLC control servo device, in order to realize the tracking scanning, the result can be real-time display, print.
(2) medical endoscope
Medical endoscope by the end of the objective lens, optical fiber image tube, of the top of the eyepiece and control handle. Lighting light is observed by image tube outer fiber exposure to an object, the reflected light through like a bunch of output. Through the handle at the end, because of the large optical fiber soft, degrees of freedom can control the deflection, transmission image distortion is small, therefore, he is check and diagnosis of human body internal diseases and some important instruments of surgical.
