摘要
介绍所研制的激光笔干涉仪.由激光笔发出的激光束在反射镜组间不断反射,使光传播距离增大,从而可以清楚地展现具有一定宽度和高度的干涉条纹,故适合于教学以及演讲中对干涉现象的演示和讲解.
By means of two reflector teams, the distance between biprism and the screen is increased, so the more seperated fringe's interval is shown clearly in the optics teaching classroom.In addition, the pen laser source makes the interferometer to move easily.
