摘要
结合颜色光学理论和光谱反射理论,给出一种获得物体表面颜色特性的计算方法。通过自行搭建的光栅光谱仪装置测量了氙灯的发射光谱和目标样片在氙灯光源照射下的表面反射特性,然后编程,分别计算光源氙灯和样片表面在氙灯照射下的色度值,同时还可以通过色度学计算公式进一步得到不同光源照射下物体表面的色度值。这一工作对研究物体透射的色度特性和荧光物质的色度特性具有一定的借鉴意义。
The method of chromaticity characteristic of object is obtained by connection of theory of color optics and theory of spectrum reflection theory. Emission spectra of Xenon lamp and the reflection characteristic of the objective surface are obtained by the experimental measurement of grating spectrometer that based on their own structures. And then it is programmed to calculate the chromaticity coordinates of the Xenon lamp light source and the sample surface irradinated by the Xenon lamp. At the same time. The chromaticity value of surface of object can also be further calculated under different light source irradition by using formula for calculating the chromaticity value. The work also has a certain reference on the methods of measurement for chromaticity of transmission objects and fluorescent objects.
