远距离灯光强度测试方法研究

本文提出了一种对于远距离灯光强度的测试方法。在讨论了测量原理的基础上,搭建了实验装置,装置运用光电技术和计算机技术完成了实验结果的量化。实验数据表明该测量方法可以判断远距离灯光的强弱,并从两个不同距离的测量结果分析所得量化值,基本满足光强与距离平方成反比的定律,验证了测量方法的正确性。

Research on the Method to Measure Distant Light

A method to measure distant light is provided in this paper.Optic-electronic and computer techniques are applied into the equipment which is designed based on Optic-Electronic principle and experimental results are obtained.The results show that the method can tell which beam is stronger,furthermore,the two groups of result produced by different distance lamp prove well the principle: Beam strength is inverse proportional to the square distance,and so prove the method itself correct.
