随着科学技术的发展,亮度计出现了瞄点式和成像式两类。本文对这两类亮度计的各项性能指标进行比较,采用两种亮度计分别对同一液晶显示器样品进行测量,对其测量结果偏差进行比较分析,通过实例证明两类亮度计的异同点,给使用者选择时提供参考。

The two kinds of luminance meters, spot luminance meter and imaging luminance meter, are both used in the photometric measurement with the development of science and technology. The comparison between the two kinds of luminance meters were demonstrated in this paper. The experiment results were compared after measuring the same liquid crystal display device with a spot luminance meter and an imaging luminance meter respectively. The differences of spot luminance meter and imaging luminance meter were presented. The results would provide some suggestions for users.
