摘　　要：在700 nm～900 nm波段范围内,用1 000℃黑体标定光纤光谱仪(200 nm～1 100 nm),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700 nm～900 nm波段的响应函数推延至400 nm～700 nm波段范围,最终得到400 nm～900 nm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550 nm～900 nm范围内,所获得的绝对光谱响应合成不确定度小于3.53%。As a referenced spectral detector,the accurate calibration of fiber spectrometer is very important.The absolutely spectral response function of the fiber spectrometer within 550 nm-900 nm 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.
