Photo-electric Temperature Measurement using Mie's Scattered Light Phenomenon : 1st Report, Theoretical Consideration

Abstract

When a homogeneous, isotropic particle of soda glass, hexadecane or others is immersed in the incident light of the laser beam, the scattering efficiency, the intensity of the scattered light and the polarization ratio of the light of these matters change according to temperature. In principle, this optical measuring method is a new-technique compared with the direct measurement method such as the thermocouple, the resistance thermometer and the spectroscopic CARS method. The analytical results using Mie's scattered light phenomenon show that the temperature measurement by this method is practically available.
