Abstract

An experimental study of the performance of an all-fiber polarimetric pressure sensor is carried out. The sensor is in the form of a multifiber assembly composed of a low- or a highly-birefringent (Lo-Bi or Hi-Bi) single-mode lead-in, a Hi-Bi sensing fiber and a Hi-Bi polarizing fiber all spliced in sequence. Theoretically the polarization behavior of the assembly is described by means of the Mueller-Stokes matrix method in the general quasimonochromatic case. The response of the sensor to hydrostatic pressure at different temperatures and with different lengths of sensing fiber is described. The spectral distribution of the semiconductor laser was monitored by changing the injection current so that the effect on the visibility and the stability of operation could be considered.
