卤钨灯辐射光谱特性及其补偿方法
Radiation Spectral Characteristics of Tungsten Halogen Lamp and Its Compensation Method
摘要
Abstract
In the field of radiation temperature measurement,blackbody furnaces are usually used for cali-bration.In order to deal with the problems of high cost and harsh measurement conditions of blackbody furnace,a method is proposed to make the spectral curve of tungsten halide light closer to the ideal black-body,that is,by measuring the spectral curve value of tungsten halide light at a series of controlled cur-rent,comparing with the blackbody curve with the highest normalization fitting degree,measuring the gen-eral compensation coefficient,and compensating the radiation emission curve of tungsten halide lamp.The blackbody furnace is replaced in a high precision range.By using a cross-correlation algorithm,the fitting degree of the radiation curve and spectral compensated curve of the tungsten halide lamp at different tem-peratures is analyzed.The experimental results show that a tungsten halogen lamp can be used to calibrate blackbody in the temperature range of 2 200~3 000 K and in the band of 700~1 700 nm,and the fitting degree can reach 0.999 9.The problem of calibration of the blackbody furnace is solved and the operabil-ity is improved.the experimental steps are simplified and the application prospect is broad.关键词
