【Abstract】 A simple fiber-optic interferometric temperature sensor is desrcr-cribed in which two singlemode polarization preserving optical fibers are used as the sensing element and the reference beam of the Mach-Zehnder interferome ter respectively.The photoelectric counting of the interference frings is received and processed with an automatic measuring system by means of pair of photodiodes and a single boad computer TP801.更多还原
