PROBLEM TO BE SOLVED: To achieve a gonio-photometric spectral imaging measurement method that is more accurate and highly practicable, and an apparatus for the same.SOLUTION: To a measurement sample surface 2, an illumination device 10 that irradiates the measurement sample surface 2 with illumination light beams from two or more angle directions, an optical lens 8 for image formation, and a black and white two-dimensional image sensor 4 are provided. Accordingly, a method and an apparatus are provided for photographing a two-dimensional image of the measurement sample surface 2 for each measurement wavelength, and measuring a deflection angle and spectral information for each pixel accurately in a short time for the entire pixels of the two-dimensional image. In particular, a gonio-photometric spectral imaging measurement method that is more accurate and highly practicable, and an apparatus for the same are achieved. |
