基于激光积分球反射计的集成黑体发射率测量研究
|
摘要
集成黑体发射率是评价其有效光谱辐射亮度不确定度的关键贡献项。建立了激光积分球反射计测量系统,对中国计量科学研究院制备的集成空腔的法向光谱发射率进行了实验研究和模拟验证。在633 nm的波长下测量了集成黑体法向光谱发射率,测量结果的标准不确定度优于0. 043%。结果表明:集成黑体辐射源在室温条件下的有效发射率高于0. 998,与STEEP3蒙特卡罗模拟计算结果偏差在0. 04%之内。实验结果与数值模拟的一致性在测量结果不确定度内吻合良好,验证了激光积分球发射计法用于评价集成黑体发射率的可行性。
Integrated blackbody emissivity is one of the key uncertainty components of its effective spectral radiance.The measurement principle and experimental system of the laser integral sphere reflectometry were established. The normal spectral emissivity of the integrated cavity blackbodys were experimentally studied at 633 nm,the experimental results showed that the effective emissivity of the integrated blackbody was higher than 0. 998,and the deviation from the model Carlo simulation result was within 0. 04%. The agreement was good within the measurement uncertainty,which validated that the laser integral sphere reflectometry is feasible to estimate the normal spectral emissivity of the integrated cavity blackbody.
