摘　　要：对传统的双棱镜测激光波长实验进行改进,用He-Ne激光器代替钠灯,去掉狭缝,用屏或墙代替移测显微镜,并采用一次成像法测两虚光源间的距离.改进后的装置简便易行,现象明显.The traditional experiment of measuring laser wavelength with biprism is improved. The sodium lamp is substituted by He-Ne laser, the slit is removed, a screen or wall is substituted for the traveling microscope and the distance between the two virtual light sources is measured by the first imaging method. The improved device can be operated easily and the phenomena is obvious.
