Abstract

The invention discloses a double-light-source color photometer with SCI / SCE test conditions compatible and an implementation method. Switch of the SCI / SCE test conditions is achieved in the mode of double-light-source active illumination, the design of the optical trap is replaced, and corresponding calibration algorithms are designed for the two test conditions. As is shown in the experimental result, the test results of the double-light-source color photometer on the SCI / SCE test conditions are obviously better than that of the prior art, and the double-light-source color photometer with the SCI / SCE test conditions compatible is more suitable for color test instruments with SCI / SCE test conditions compatible and has prominent value.

Description

technical field [0001] The invention relates to the technical field of color measuring instruments, in particular to a color measuring instrument based on dual light sources compatible with SCI / SCE test conditions and an implementation method thereof. Background technique [0002] In 1971, CIE (International Commission on Illumination) recommended four standard lighting and observation geometric conditions for reflection sample measurement: vertical / 45 (0 / 45), 45 / vertical (45 / 0), vertical / Diffuse (0 / d), Diffuse / vertical (d / 0). For the sake of discussion, the various lighting and viewing conditions can be reduced to the three most common geometric conditions: diffuse lighting, 8-degree viewing angle, including specular reflection components (d / 8:i); diffuse lighting, 8 degree viewing angle, eliminating specular components (d / 8:e); and 45° ring illumination, vertical viewing (45 / 0:c). Since the measurement result is independent of the surface gloss of the material when meas...
