摘要建立了以光纤半球发射器（HEWOF）为特征的视觉漫透射密度基准。特性化测量表明,其几何与光谱条件符合国际标准ISO 5的规定。合成不确定度为0.0015 (0<D<4.5)和0.0054(5.0≤D<6.0)。利用复合漫射器能与光源和探测系统分别组合的优点,验证了透射测量亥姆霍兹倒易律的有效性。

Abstract：Primary standard densitometer for visual diffuse transmission density, characterized by hemispherical emitter with optic fiber（HEWOF）is established. Characterization measurements have showed that the geometric and spectral conditions of this densitometer meet the specifications of ISO 5. Its combined uncertainties are 0.0015(0<D<4.5) and 0.0054(5.0≤D< 6.0).Taking the advantage of that the composite diffuser can be combined respectively with light source and detection system ,the validity of Helmholtz reciprocity for transmittance measurement is examined .

Key words： Metrology Diffuse transmission densitometer Hemispherical emitter with optic fiber Diffusion coefficient Auxiliary step tablet Helmholtz reciprocity examination
