全视角测量系统的校准方法

Calibration Method of Omnibearing Viewing Angle Measurement System

全方位视角测量系统是针对显示器等可视产品的可视角、色亮度等参数进行全面、准确、高效测量的一种测量方法。利用镜头组的独有的光学傅里叶转换系统与CCD传感器配合,对显示产品的视角进行全方位的精确和快速测量。但该系统的计量问题目前在国内尚无完整的解决方案。以量值溯源为目的,针对全视角测量系统的校准方法和系统设计进行了研究。

Omnibearing viewing angle measurement system is a international advanced measurement method of display＇s viewing angle, luminance and chromiance. The system measures the display＇s omnibearing viewing angle by using lens＇s optical fourier transformation and CCD sensors. But the metering problem of this system has not been soleved in our country. The method of calibration and the calibration system design are researched in this paper for the purpose of the traceability of value.
