Abstract
The quartz optical fiber bundle sensor for the image processing and temperature measurement is consisted by a number of optical subfiber bundles, each optical subfiber bundle is consisted by tow optical fibers. One optical fiber in all subfiber bundles are then bundled up for the image transportation and another optical fibers in all subfiber bundles are then bundled up for the image processing and the temperature measurement, and the temperature field of the whole image can be obtained by the image processing. The direct coupling theory between the optical fiber bundle and the measured target is studied in this paper. Our theory and experiment research proved that the target power transported by the optical fiber bundle does not depend on the coupling distance between the target and the optical fiber bundle, and does not depend on the coupling angle between the target surface normal and the axis of the end surface of optical fiber bundle when this angle is changed between +/- 15 degrees. Hence this instrument utilization and calibration is very easy and convenient. The temperature measurement from 120 degrees C-450 degrees C is realized by this instrument, the image resolution is better than 20pl/mm, the temperature solution is smaller than 0.2 degrees C. This instrument is a very good monitor for the medical surgical operation.
