✦ Synopsis

This paper presents a fibre-optlc sensor to measure weight m mobon based on a multiple libre-optlc mterferometer

The tierentlal phase between the arms of the Interferometer produced by the pressure IS compensated by a feedback system, thus convertmg pressure Into voltage This sensor can be used to separate the Induced phase changes produced by two measurands actmg simultaneously on the sensmg arm Results are presented that show the hnearlty of the detectlon scheme
