摘要
本文介绍了夜间天空亮度及其测量方法，同时介绍了作者研制的一种便携式亮度计。该亮度计的主要性能为：精确度：±５．４％，相当于±０．０６ｍａｇ；分辨率：１０－６ｃｄ／ｍ２，相当于２７．４ｍａｇ／□″；重量：３．５ｋｇ。
The knowledge about the night sky brightness and the methods of measuring night sky brightnes are introduced in this paper.A convenient luminometer developed by authors is also introduced.The main specifications of the luminometer are as follow:accuracy:±5.4%(corresponding to±0.06mag);resolution:10-6cd/m2(corresponding to 27.4mag/□');weight:3.5kg.
