Abstract

Coherent anti-Stokes Raman spectroscopy (CARS) is considered as a standard technique to measure the temperature for combustion diagnosis. But results of evaluation on the accuracy of the CARS temperature is not sufficiently conformed in high temperature region above 1500 K, because a standard source of temperature is not easily available. In this work, we made a graphite-tube blackbody furnace. Measuring temperature of the furnace with a radiation pyrometer and CARS, we evaluated the accuracy from 1000 K to 2000 K.
