Abstract
Results of experimental studies on coherence multiplexing of a greater numb er of sensors based on highly birefringent fibers are presented. We propose a flexible detection system based on a Wollastone prism which allows demul tiplexing of several serially connected pressure and temperature sensors. T he proposed method of multiplexing is simple, inexpensive, and assures abso lute accuracy of each multiplexed sensor about 0.5% of the full scale.
