To apply optical fiber image guide to harsh radiation environments, we have developed new image guide systems for color correction and new type image guide with a semiconductor laser for infrared imaging. We irradiated the image guides utilizing a 60Co gamma source. Measured images with the visible type image guide became dark and yellowish because of radiation induced loss. By using a color correction system, the original color of the images can be obtained. In the case of infrared type image guide, because of low radiation induced loss in the infrared region, the degree of darkening was less than half of that for the visible type of image guide. When irradiating a fixed length of 2.5 m, the dose limit for using image guide was estimated to be 3.0×105 C/kg (7.9×109 R) with the visible type image guide and be 4.5×105 C/kg (1.2×1010 R) with the infrared type image guide. These radiation resistivities were more than 103 times of that for usual CCD cameras. With these techniques, image guide can be applied to harsh radiation environment.
