照度测量不确定度研究

Research on Uncertainty of Illuminance Measurement

照度是保障演出效果的重要技术指标,照度测量是演出场馆(剧院)验收及使用环节的重要测量项目。测量不确定度用来表示测量值分散性和测量结果的可靠性。本文主要从照度定义、照度测定方法和原理、测量不确定度定义、测量不确定度来源分析、测量不确定度的评定对照度的测量不确定度进行研究,进而为测量结果的可靠性和检验检测工作的准确性提供技术支撑。

Illuminance is an important technical index to ensure performance effect,and illuminance measurement is an important measurement item in the acceptance and use of performance venues(theaters).Uncertainty of measurement characterizes the dispersion of measured values and the degree of confidence in reaction measurement results.In this paper,the measurement uncertainty of illuminance was studied from the definition of illuminance,the method and principle of illuminance measurement,the definition of measurement uncertainty,the source analysis of measurement uncertainty,and the evaluation of measurement uncertainty.And then it provides technical support for the reliability of measurement results and the accuracy of inspection and inspection.
