摘要
光源的光强分布是衡量其质量的重要性能指标,为了能便捷地检测光源在不同方向角的光强分布特性,设计了一种新型光强分布测量装置。该装置中有一个可以围绕中心点偏转的平面反射镜,当反射镜偏转时,将光源不同方向角的光强反射进光电探测器中,从而实现对光源不同方向角的光强分布进行测量的目的。
The intensity distribution of light source is an important performance index to measure the quality, in order to be able to easily detect light source on the intensity distribution characteristics from different direction angle, this paper designs a new type of light intensity distribution measurement device. There is a plane mirror around the center deflection of the device, and when the re- flecting mirror deflects, the light from different direction angle reflects light intensely into the photoelectric detector, so as to achieve the purpose of measuring light intensity distribution of light sources from different direction angle.
