颜色测量知识 – 关于色差仪的照明和观察几何

Knowledge of colour measurement About the illumination and observation geometry of chromatic aberration instrumentsThe human eye cannot quantify color correctly, but we can use chromatic aberration instruments and spectrometers to measure color, which is quite simple.And the position relation among the lighting source, the measured sample and the sensor is the illumination observation geometric condition in the color measurement, referred to as geometric condition.Cie15:2004 recommends ten types of reflective sample measurement geometry:1.从:8 Diffuse illumination, 8° receiving, including specular reflection component.The sample [...]
