Abstract:
1. A reflection characteristic measuring apparatus, comprising: a light source for illuminating a sample; a spectral intensity measuring section for measuring a spectral intensity of light reflected by the sample illuminated with illumination light from the light source; a reference value acquiring section for acquiring reference values relating to an emission characteristic of the light source; a storing section for storing multiple standard spectral characteristics, or multiple calibration data based on the multiple standard spectral characteristics, obtained in advance with corresponding reference values; a selecting section for selecting a standard spectral characteristic, or a calibration data based on the standard spectral characteristic, corresponding to a reference value acquired at the time of measuring the spectral intensity of light reflected by a sample, from the multiple standard spectral characteristics or the multiple calibration data stored in the storing section; and a computing section for calculating a spectral reflection characteristic of the sample based on the spectral intensity using the standard spectral characteristic or the calibration data selected by the selecting section.
