Abstract

PURPOSE:To perform a simple and high-precise evaluation of a color of an object which varies in an observation direction, by a method wherein a reflecting or transmitting light, which is generated in case a sample is illuminated from one-way direction, is received in a plural number of directions, and spectroreflection coefficient and the like is compared and measured. CONSTITUTION:A reflecting light or a transmitting light, which is generated in case a sample is illuminated from one-way direction, is received in a plural number of direction, and a spectroreflection coefficient or a difference in or a ration of a three- excitation value in their respective directions is operated and indicated. For example, a white light, radiated from a light source 1, is focused through a lens 2, and a sample 3 is irradiated with the white color. Two-way light, which the sample surface reflects, is fed directly to a slit 11 in a spectrophotometer through light guides 10a and 10b, and is separately image-formed on photo detector arrays 13a and 13b by means of a concave diffraction lattice 12. The outputs are compared at every wavelength by means of an operational amplifier 14, and the compared results are indicated in an indicator 15. This method permits the high-precise measurement of a color of an object, which varies in the direction, by means of a simple device.
