REAL-TIME MEASUREMENT OF TEMPERATURE-FIELD WITH ICCD AS SENSOR (II) -PRINCIPLE AND METHOD FOR OPTIMUM DESIGN OF WAVELENGTH

The colorimetric method for real-time measurement of temperature field using ICCD as sensor was developed. In order to ensure the accuracy a nd sensitivity, the relationship between the ratio response of two-col or images and radiant property of body, transmission property of filte r, spectral response of ICCD is discussed. The analysis is based on co mputer calculation of the established mathematical model. On the basis of the analysis, optimum wavelengths are obtained for a given sensor system. Experimental work was carried out to check the correctness of the theoretical results. The method is useful for general purpose of s tudy and design of the developed system.
