| 摘 要： | 低温辐射计是当前光辐射功率计量的最高标准,其测量精度的评价可以通过不同低温辐射计之间的比对来完成。开展了不同定标光路的低温辐射计比对实验。实验采用中国科学院安徽光学精密机械研究所研制的陷阱探测器作为传递标准,在633 nm波段对传递探测器的光谱响应度进行了绝对标定。比对结果表明,传递探测器的绝对光谱响应度的测量一致性为3.610-3,定标总合成不确定度为3.310-4(k=1),实验结果验证了两家单位低温绝对辐射计定标系统的可靠性和高精度。

| Abstract: | Cryogenic radiometer currently is used as the supreme standard for the measurement of light power, whose accuracy evaluation can be acquired through the results between different cryogenic radiometer equipment. With trap detector serving the transfer standard and the calibration optical path in cryogenic radiometer being distinct, a comparison experiment was carried out between two equipments for the first time in China. The absolute spectral responsivity of transfer standard was calibrated at 633 nm wavelength. The results show that the consistence of absolute spectral responsivity is 3.610-3 and the combined uncertainty is 3.310-4(k=1). It is proved that the two cryogenic radiometer equipments are of high reliability and accuracy. |
