Title: Optical fiber interferosensor, signal-processing system for optical fiber interferosensor and recording medium

Abstract: A low coherence light of wide range is fed into a Fabry-Perot load cell having a measured clearance varied in response to physical quantities such as force and pressure or the like to modulate its wavelength. The measured clearance is calculated by the variable gap Fabry-Perot interferometer and the signal processing part in the optical sensor and further the physical quantities are measured.
