紫外探测器相对光谱响应度比较法不确定度 Ultraviolet detector Relative spectral responsivity Comparison measuring Uncertainty

摘要

光谱响应度是探测器的重要技术参数之一, 随着紫外探测技术的发展, 精确测量紫外探测器的光谱响应度变得越来越重要。文章分析了紫外ICCD(UV-ICCD)相对光谱响应度的测量原理, 采用了直接比较法测定待测探测器的相对光谱响应度, 并基于具有优异紫外响应能力的科研级光谱仪建立了UV-ICCD光谱响应的测量装置。实验获取了UV-ICCD的相对光谱响应度曲线, 从曲线中可以看出, UV-ICCD光谱响应范围为220～300 nm, 峰值响应在270 nm附近,表明该器件具有日盲特性。不确定度分析结果显示, UV-ICCD相对光谱响应度测量的最大不确定度约为7.79％, 满足测量要求。

Abstract

The spectral responsivity is one of the important parameters of detector. With the development of ultraviolet detect technique, accurate measure for the spectral responsivity of ultraviolet detector becomes more and more important. A measure principle which is based on the direct comparison measuring method for relative spectral response measurement of the ultraviolet ICCD is introduced. Based on the scientific-grade spectrometer with ultraviolet responsivity, a measurement facility was built. The relative spectral responsivity curve of the ultraviolet ICCD was obtained. The curve indicates that the spectral response of UV-ICCD is from 220 to 300 nm and the peak response is near 270 nm, which indicates that the UV-ICCD is solar blind. The analysis of the uncertainty shows that the most largest uncertainty of measurement for relative spectral responsivity of the UV-ICCD is 7.79% and meets the requirement.
