迈克尔逊干涉仪用步进电机驱动装置的设计

摘要

Michelson interferometer is a precision optical instrument. Any micro clearance in device may cause relatively large null-space error. The space can be ignoreless only if the device works on the same direction and keeps no stop. Relative to manul control, step motor keeps the device on working, the null space is hardly caused. So the accuracy of experimental results is promoted.%迈克尔逊干涉仪是一种精密的光学仪器，传动装置中微小的间隙都会使仪器引入较大的空程，只有当传动装置朝一个方向不间断地行进时才能有效减少该误差的发生，因此相对人的手工操作，用步进电机驱动的方式可使仪器一直处于工作状态中，减少了空程发生的概率，从而提高测量的准确度。
