380～780 nm总光谱辐射通量量值导出及不确定度评定
|
摘要
叙述了光源380~780 nm总光谱辐射通量量值导出的基本原理。该量值基于测量灯的总光通量及用变角辐射计测量灯的光谱辐射强度相对分布,溯源至总光通量国家基准和高温黑体光谱辐射照度国家基准。总光谱辐射通量量值导出的不确定度主要影响因素包括总光通量、光谱辐射标准灯、光谱辐射计自身特性、变角辐射计(机械部分)和测量系统重复性,扩展不确定度U=3.3%~1.6%,k=2。
The basic principle of the realize 380 ~ 780 nm total spectral radiant flux( TSRF) scale is described,based on measuring total luminous flux and measuring relative spectral radiant intensity distribution by a goniospectroradiometer. The TSRF quantity traces to the primary standard of total luminous flux,and the primary standard of spectral radiant intensity,the high temperature black body. The measurement uncertainty components of TSRF scale include the total luminous flux, spectral radiant intensity standard lamp, the array spectroradiometer, the goniospectroradiometer( mechanics) and the repeatability. The expanded uncertainty is evaluated to be U = 3. 3% ~1. 6%,k = 2.
