摘　　要：本文系统地介绍了积分球辐射源的光谱辐射特性的测试方法．通过实验测量了一内径为 １２００ ｍｍ，出光面直径为 ２００ｍｍ的积分球辐射源在 ３５０～２５００ ｍｍ波段内的绝对光谱辐亮度，分析了测量不确定度，并对系统的稳定性、出光面的平面和角度辐射均匀性、各亮阶之间的线性等辐射特性做了定量评估．Spectral radiant characteristics of integrating sphere was experimentally studied in this paper. Absolute spectral radiance and its uncertainty from an integrating sphere with 1200 mm inner diameter and 200 mm exit diameter were measured within 350-2500 um. The stability, linearity, planar and angular radiant uniformity were characterized as well.
