杨氏双缝、菲涅耳双棱镜、双面镜以及劳埃镜等实验测定光波波长时，均是用测量干涉条纹宽度法。

The wavelengths are determined usually by measuring the widths of interference fringes in many experiments such as Young's slits, Fresnel biprism, bimirror and Lloyd's mirror etc.

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。

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.
