本文介绍光电探测器相对光谱响应度标准的实验装置、方法及测量结果。
This paper describes the experimental system, measuring method and results of the standard for the relative spectral responsivity of optical radiation detectors.
由于腔体热释电探测器在宽光谱范围内具有相对平坦的光谱响应度，因此经常被用作标定探测器相对光谱响应度的工作基准。
The cavity pyroelectric detector is usually used as the work norm to calibrate relative spectral responsivity of detectors because of its flat spectral responsivity in broad spectra range.
