制作滤色器测色仪的最大困难是模拟CIE光谱匹配函数。到目前为止,国内外所采用的方法都是将滤色器设计成串列式或并列式来修正光电器件的光谱响应。如图1和图2所示。但这两种方法在测量精度要求较高时不能使用。本文研究修正程度更好的串并列式滤色器,提出分析该滤色器的方法及建立相应光谱透过率的数学模型,并进行 The biggest difficulty in making color filter colorimeters is the analog CIE spectral matching function. So far, the methods adopted at home and abroad are to design the color filters into tandem or parallel to correct the spectral response of the photoelectric device. As shown in Figure 1 and Figure 2. However, these two methods can not be used when the measurement accuracy is high. In this paper, we study the modified parallel-series color filter, propose the method of analyzing the color filter and establish the mathematical model of the corresponding spectral transmittance.
