AAbsolute spectral radiation calibration of fiber spectrometer
-
摘要: 在700nm~900nm波段范围内,用1000℃黑体标定光纤光谱仪(200nm~1100nm),获得其在该波段范围内的绝对光谱响应函数。通过测量光纤光谱仪对不同色温下卤钨灯的光谱响应,将700nm~900nm波段的响应函数推延至400nm~700nm波段范围,最终得到400nm~900nm波段内的绝对光谱响应函数。光纤光谱仪对不同色温下卤钨灯的5次测量结果表明:在550nm~900nm范围内,所获得的绝对光谱响应合成不确定度小于3.53%。Abstract: As a referenced spectral detector, the accurate calibration of fiber spectrometer is very important. The absolutely spectral response function of the fiber spectrometer within 550nm-900nm was obtained with a new technique, which avoids using a high temperature blackbody, and the uncertainty of the response function is less than 3.53%. Besides, a novel method is used to obtain the color temperature of the light source with characteristic of gray body.
