摘要
采用互垂光路的干涉演示仪具有便于携带，操作简便，现象直观等特点，便于教师随堂演示互垂光路干涉的原理、相干光的获得、干涉光强分布及条纹移动等．
The crossed optical path is used in the demonstration，easy to carry about，easy to op-erate and the phenomena is very obviously. In the classroom this instrument can demonstrate funda-mentals of interference with crossed optical path，coherent light，light intensity distribution and mov-ing of interference fringers，etc.
