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。
This paper introduces a filter optimization design method of photoelectric integral color light illumination instrument. The design error caused by the difference of spectral transmittance and vertical incidence caused by oblique incidence of light beam was investigated. A modified model of diffuse transmittance of incident colored glass was established and a filter based on the modified model Chip matching method, used in color illumination measuring instrument design. The experiment is designed to verify the matching results. The experimental results show that the modified model can effectively reduce the design error.
