Direct Measurement High Resolution Wide Range Extreme Temperature Optical Sensor Using An All-Silicon Carbide Probe

Abstract

We propose and demonstrate a temperature sensing method using an all-silicon carbide probe that combines wavelength-tuned signal processing for coarse measurements and classical Fabry-Perot etalon peak shift for fine measurements. This method gives direct unambiguous temperature measurements with a high temperature resolution over a wide temperature range. Specifically, temperature measurements from room temperature to 1000°C are experimentally demonstrated with an estimated resolution varying from 0.66°C at room temperature to 0.12°C at 1000°C. The proposed sensor has applications in next-generation greener gas turbines for power production. © 2009 Optical Society of America.
