摘要

为了测量实验室研制的辐射计的角响应，组装了一个自动化系统并对其进行了表征。主光源为1000W的QTH灯，紫外线辐射计为500W的Hg(Xe)灯。光束有效直径40 mm，半发散10mrad，空间均匀度优于97%。在大角度下，对辐射计定位误差1°的估计误差可达5%。在这项工作中，详细介绍了该系统以及用实验室和商用辐射计所获得的测量结果。

System for measuring the angular response of radiometers

To measure the angular response of radiometers developed in the laboratory, an automated system was assembled and characterized. The main light source is a QTH lamp of 1000W and for UV radiometers a Hg(Xe) lamp of 500W. The light beam has a useful diameter of 40 mm, a half divergence of 10mrad and the spatial uniformity is better than 97%. Errors up to 5% at large angles were estimated for misalignments of 1° in the positioning of the radiometers . In this work details of the system and results of measurements obtained with radiometers developed in the laboratory and with commercial ones are presented.
