Paper Abstract

An optical temperature-sensing instrument based on broadband polarimetric differential interferometry (BPDI) technology is developed for ultrahigh temperature measurement in chemically corrosive environments. A single-crystal sapphire disk with inherent birefringence is employed as a sensing element in this instrument. Absolute temperature information is obtained and the measurement results are relatively immune to optical source power fluctuations and transmission fiber losses. Other advantages of this sensor are its mechanical simplicity, high resolution, and great accuracy over a wide measurement range.
