| Abstract | At the National Research Council of Canada (NRC), the scale of diffuse spectral reflectance in the UV and visible range is realized using an integrating sphere method known as the Modified Sharp-Little method and has been wellcharacterized and validated. More recently, a gonioreflectometer has been designed to capture the bidirectional reflectance of reflecting objects. This system incorporates a diode-array spectroradiometer and is prone to non-linearity errors. In this paper the magnitude of this non-linearity error is evaluated using several diffusely reflecting materials by comparing the angular-integrated reflection indicatrix measured with the gonioreflectometer with results obtained using a transfer spectrophotometer that is traceable to the sphere-based NRC Absolute Reflectometer. |
