Abstract

The promising character of the use of the As-Se-chalcogenide glasses as the fiber-optic temperature sensors (as sensing material for FOTS) having optimal matching with spectral characteristics of the radiation source and receiver has been shown. The method of calculating the transmission characteristic of the fiber-optic temperature sensors has been elaborated. The calculation was carried out for the double-channel optical scheme with a (sensing element) in a form of a ~0.6 mm thick As45Se55 plate. In accordance with our calculations, the As-Se glasses can be used as the optimized sensitive elements for fiber-optic temperature sensors with input signal variation about 6 μА per 1 degree..
