Paper Abstract

A wavelength domain technique based on the detection of peak wavelength in the interference pattern was proposed and applied to a reflection type polarimetric temperature sensor made of polarization maintaining fibers. The measurement equation that relates the temperature variation linearly to the shift of the peak wavelength in the interference pattern was derived. An experimental sensor was setup to verify the effectiveness and the accuracy of the detection technique over an applied temperature range from -40°C to 80°C. Experimental results agree well with theoretical prediction.
