摘要
介绍了激光干涉法长度测量的基本原理,提出在不更换和调整系统中光学器件的条件下,实现线位移和角位移—机测量集成装置的设计思想。该装置结构简单,操作方便,既可直接观察条纹变化情况,又能显示出具体的测量值。
The paper introduces the basic principle of measuring displacement with laser interferometer,and gives a designing idea that realizes length measurement and angle measurement on one apparatus.The apparatus has simple structure and convenient operation.The absolute results of the measurements can be shown directly,meanwhile one can also observe the changes of the interference fringes.
