【摘要】 本文根据0∶d漫反射比与0∶45漫反射因数的物理定义,从漫反射模型中几何条件的差异入手,给出了两者之间的转换公式,提出了一种通过标准白板0∶d漫反射比与相对辐亮度因数计算其0∶45漫反射因数,进而得到标准白板0∶45色度、白度量值的方法,成功溯源至色度基准,实现与BIPM.CCPR-K5比对结果链接。更多还原

【Abstract】 This paper combines the physical definitions of 0:d diffuse reflectance ratio and 0:45 diffuse reflectance factor and proposes a conversion formula between them according to the difference of geometric conditions in the diffuse reflectance model. Furthermore, a method is proposed to calculate the 0:45 diffuse reflectance factor from the 0:d diffuse reflectance ratio and the relative radiance factor of a standard whiteboard to obtain the 0:45 chromaticity and whiteness values of a standard whiteboard, which is successfully traced to the chromaticity primary reference and transferred to the comparison results of BIPM.CCPR-K5.更多还原
