Abstract

Several on-off optical fibre temperature probes have been designed with liquid crystals as thermosensitive dements. These probes have been multiplixed with succes in a two sensors system. When the OTDR technics is used as signal processing it can be shown that an internal signal reference exists. Light intensity fluctuations effects on the sensors can be efficiently cancelled
