色差测量的几何条件与设备

Geometric Condition and Facilities for Color Difference Measurement

由于色差测量目的以及被测涂层表面所含色浆对入射光反射的特性和纹理不同,应当选择不同的色差测量设备和测色几何条件。介绍了市场上常见的几种不透明物体的色差测量设备,并就其光路原理和其对应测色几何条件下测量数据的意义及适用场合进行了说明。

According to different purpose of color difference measurement and the reflective characteristico of the colorants in coatings, different test facilities and geometric condition should be selected. Several commonly used color differrence test facilities for opacity colors, their optical test principles, geometric conditions, result indication and uses are described.
