不同波长处的相对光谱功率对光源颜色的影响

Judgement of Sensitive Wavelengths which Have Influence on Light Sources Color

从色度学理论出发，在1976（L*a*b*）颜色空间内，探讨了不同波长处的相对光谱功率分布变化对光源颜色的影响情况，建立了数学表达式，从而能准确地判断各个波长点对光源颜色的影响。并且以A光源和D65光源为例，判断了A光源和D65光源各个波长处的单位光谱功率的改变对颜色的影响。运用这个数学表达式，在模拟标准光源的过程，就可以对某些波长点实行重点匹配，以便更准确的对标准光源进行模拟。在标准光源的模拟过程中，发现不同波长处的相对光谱功率分布变化对光源的颜色有不同的影响。

During the simulation of standard light sources, discovering the change of relative power distribution has differently influence on light sources. With theory of colorimrtry, the thesis discuss the influence on light sources caused by the change of relative power distribution in 1976 (L*a*b*) color space, proposed mathematical formulation from which the iofluence on light sources can be judged at each wavelength.As examPles, the influence caused by the change of relative power distribution of A light source and D65 light source at each wavelength is judge. With the mathematical formulation, relative power distribution at some wavelength is mainly matching to get accurate simulation of standard light sources.
