Abstract
A water-mist-penetrating three-wavelength temperature measurement device and method for a high-temperature environment, the device including a housing, a three-waveband beam splitting detection module and a computing unit, the housing provided with an optical aperture, the three-waveband beam splitting detection module arranged in the housing, and including a trichroic prism, three radiation detection assemblies, the trichroic prism able to receive the light signals entering via the optical aperture, and emit radiation signals having different wavelength bands through three emission faces, respectively; the three radiation detection assemblies able to receive radiation signals having different wavelength bands emitted from corresponding emission faces, and convert them into electrical signals, respectively; the computing unit able to receive the electrical signals, and perform calculation and analysis to determine a temperature value of a target to be measured; the method including: temperature measurement data acquisition, data fusion, parameter tuning, and model application.
