摘　　要：本文研究了直接耦合式特种石英光纤束低温辐射测温仪的理论和设计，实现了低至１２０℃的温度测量。研究表明，光纤束接收和传输靶目标的辐射功率与光纤束输入端和靶目标间距无关；且当光纤束轴与靶目标表面法线夹角小于±１５°时，也与夹角无关。因此仪器的校正和使用非常方便。在工业、农业、生物学和激光外科手术等领域有广泛用途。温度分辨率小于０．５℃。The theory and the design of the low temperature radiation thermometer with a special quartz optical fiber bundle in direct coupling mode are studied in this paper. The temperature measurement as low as 120℃ has been realized. Our research demostrates that the power received and transported by the optical fiber bundle does not depend on the distance between the input end of the optical fiber bundle and the measured target,and does not depend on the included angle between the axis of the optical fiber bundle and the normal of the target surface when this included angle is smaller than ±15°. Hence the calibration and the application of this instrument are very convenient. It can be widely applied in fields of the industry,the agriculture,the biology and the laser surgical operation. Its temperature resolution is smaller than 0 5℃.
