显示用亮度计的校准

Calibrating Methods for Luminance Meters Used on Display Industry

介绍了显示行业常用的成像式亮度计、屏幕亮度计及彩色分析仪的测量原理及其校准方法,由于仪器测光原理、结构特性不同,所以适用的校准方法也会有所差别,为保证测量结果的准确性,需合理选择相应的校准方法。

Imaging luminance meters, screen luminance meters and color analyzers, are often used on the display industry. In this paper, the measuring principle and the calibrating methods of these three kinds of instruments were introduced. The measuring principles and the structures are different from each other, so the calibrating methods for these instruments are also different. In order to ensure measurement accuracy, the appropriate method should be chosen for the calibration of different luminance meters.
