Filter Optimization Design for Photoelectric Integral Light Source Color Illumination Instrument

介绍了一种光电积分式光源颜色照度测量仪器中的滤光片优化设计方法。研究了实际测量时由于光束斜入射导致的滤光片光谱透射率与垂直入射的不同所导致的设计误差,建立了漫入射有色玻璃透射率的修正模型,提出了一种基于修正模型的滤光片匹配方法,应用于颜色照度测量仪器的设计。设计了实验对匹配结果进行验证,实验结果证明修正模型有效地减小了设计误差。

Filter optimization design method of photoelectric integral light source color illumination instruments is introduced. The design error is caused by the beam oblique incidence which leads to the filter spectral transmittance different from that under of normal incidence. The diffuse incident colored glass transmittance correction model is established. The model is applied to the color illuminance measurement instrument design. Experiments are designed to verify the matching results, and the experimental results demonstrate that the correction model reduces the design error effectively.
