摘　　要：针对双棱镜干涉实验中二次成像法存在的缺陷,提出一种新的测量光波波长方法:等大成像法.通过对等大成像法原理阐述、误差理论分析,并与二次成像法作比较,得出该方法的优点:原理简单、操作简便、测量精度较高.该方法也是对二次成像法的进一步完善和补充.In view of the defects of second imagery in the biprism interference experiment, this paper proposes a new method to measure wavelengths of light： equal imagery. After analyzing the principle and theoretical error of equal imagery, and then comparing it with second imagery, the advantages of this method is obvious： simpler principle, easier operation and higher measurement accuracy. This method is also an improvement and supplement of second imagery.
