Abstract

PURPOSE:To perform the remote colorimetry of the surface of a moving object continuously with a high precision and a high responsiveness, by irradiating a white light, which has >=200-fold illuminance of an external light, to the surface of the moving object at 45 deg. to the surface alignment. CONSTITUTION:The white light having >=200-fold illuminance of an external light is irradiated to the surface of a moving object 10 at an angle theta=45 deg. to a furface alignment C from a white light source 14 through a lens 16. A surface alignment component out of the irregularly reflected light from the surface of the object 10 is focused by a condenser lens 20. A slit 22 prescribes a measuring place on the focusing surface of the lens 20. A collimator lens 24 collimates the light transmitted through the slit 22. A diffraction grating 26 subjects the light to spectral diffraction, and spectral components are reflected on a concave mirror 28, and intensities of them having respective wavelengths are detected simultaneously by a photodiode array 30. The electric signal for each wavelength is subjected to an operation processing in an operation processing device 31, and an average chromaticity or a color difference from a standard sample on a certain area in the running direction of the surface of the moving object is attained continuously.
