彩色成像亮度计能在几秒钟之内一次完成数以万计个物点的测量,因此它非常适合于测量显示器的亮度、颜色及其分布.分析了彩色成像亮度计测量 CRT 和 LCD 显示器的不确定度,主要分析了光谱失配所引入的不确定度,结果表明系统响应的光谱失配造成了较大的测量不确定度.介绍了一种应用于彩色成像亮度计测量 CRT 和 LCD 显示器的光谱校正方法,结果表明这种校正方法能有效减少测量不确定度.

An imaging color luminance meter can measure a large number of object points in a single opera-tion costing just several seconds. So it is an ideal instrument for measuring the luminance, color and their distributions of displays. The measurement uncertainties of the imaging color luminance meter measuring CRT and LCD displays are analysed, mainly for the spectral mismatch uncertainty contribution. The re-sults show that the spectral mismatch of the system responsivity causes large measurement uncertainties.A correction method for the spectral mismatch is introduced, both for CRT and LCD displays. The results show that the method can reduee the measurement uncertainties significantly.
