You may have seen white light split into colours when it passes through a triangular prism. This is called dispersion.
你能看到，当白色光通过三角棱柱时，会被分解为不同颜色的光，这就叫做散射。

A new principle is proposed to pseudocolor-code the differential interference in the grating-diffraction interferometry with extended white light illumination by using dispersion effect of a prism.
在光栅谱衍射干涉法的基础上，本文提出用色散效应产生的相位体微分干涉条纹，进行实时假彩色编码的原理。
