Abstract

This paper proposed a solution about low cost multi-channels Gallium Arsenide (GaAs) absorption-based fiber optic temperature sensing system, which can get specific channel temperature information at pre-set time slots by combining time division multiplexing technology and fiber optic multiplexing module. Established an seven channels fiber optic temperature sensing system using only one spectrum analysis unit and achieved -/+ 1°C temperature resolution, 2Hz measuring frequency at temperature range from 0°C to 150°C.
