摘　　要：本文对双棱镜干涉实验装置进行了改进,采用新的半导体激光器和光缝代替钠光灯和原光缝,使双棱镜干涉实验具有光路调节方便、干涉图样清晰等优点,并对人视激光替代钠光做双棱镜干涉实验的科学性作了实验验证。The instrument of double prism is improved in this article. The semiconductor laser and the new light split are used instead of the light source of sodium and the former light split ,which makes it easier to adjust the light trace and forms clear interference fringes. The test proves that it is possible to use laser instead of the light source of sodium.
