针对光学伪装勘察和检测的特殊性，在380～800 nm波长范围里，比较了不同颜色样品分别在太阳光和D65光源下三刺激值的差别，采用CIE1976L*a*b*空间分析了2种光源下颜色样品的色差。结果表明，太阳光作为光学伪装勘察和检测的标准光源更加客观、准确。

Difference of tristimulus values of different colors under light source of sunlight and D65 was compared in the 380nm to 800nm wavelength range. The color difference of same samples in the two light sources was analyzed using CIE1976L*a*b* color space. The results showed that standard light source of sunlight for investigation and detection of optical camouflage is more objective and accurate.
