3 Overview

3.1 Principle The colorimeter is used to measure the surface color and chromatic aberration of non-fluorescent objects. Colorimeter (including colorimeter, below) The same is composed of three parts. the lighting system, the detection system and the data processing system, and the output result (or the necessary number) Learning processing) is the tristimulus value X, Y, Z (or X10, Y10, Z10), calculated chromatic coordinates x, y or color difference. The total spectral sensitivity of the instrument (light source, optics) according to the color measurement principle recommended by the International Commission on Illumination (CIE) The comprehensive response of the system and the detector should be in accordance with the relationship of formula (1) or formula (2). For C/2°. ï) (1) For D65/10°. ï) (2) Where. S(λ)---relative spectral power distribution of the instrument source; SC(λ), SD(λ)---the relative spectral power of the standard illuminant C and the standard illuminant D65, respectively cloth; K1, K2, K3---wavelength-independent constants; Τx(λ), τy(λ), τz(λ)---relative spectral transmission of a modified filter that fits the color vision characteristics of the human eye in the instrument ratio; ...
