Measuring Method for Transmittance of Semitransparent Object by Infrared Thermography

WANG Chunfeng;ZHAO Xiaolong;Institute of Mechanical and Electrical Engineering, Nanjing Vocational College of information Technology;College of Power Engineering,Naval Univ. of Engineering;  
A theoretical model for transmittance measurement of a semitransparent object has not been developed nor has the effects of temperature change of the measured material on transmittance measurement results been considered according to the E1897-97 standard. First, according to the principle of infrared temperature measurement and the measurement methods and conditions under the E1897-97 standard, a theoretical formula for measuring the transmittance of a semitransparent object was derived. Second, several semitransparent double-sided silicon with different specifications were selected, and experimental testing was carried out. Thirdly, the experimental testing values, theory calculation, and calibration values of semitransparent object transmittance were analyzed and compared. The error of the measured transmittance values under different temperature conditions was obtained and compared with theoretical values. The error of the measured transmittance values was also obtained compared with the factory calibration value, and the causes of measurement error were analyzed. Finally, a method to reduce the measurement error of transmittance was proposed and verified by experiments. The experimental results show that by considering the temperature change of the tested material, the theoretical calculation formula was modified, and an improved semitransparent object transmittance measurement method was adopted. The error between the correction value and calibrated value was reduced to less than 3%. Thus, the correctness and feasibility of the improved transmittance calculation model and transmittance measurement method are proven.
