| 针对单点式激光测振仪在测量中的缺陷，本文提出了一种聚焦扫描的测量方式。利用三个步进电机实现对聚焦扫描的控制，其中一个电机控制透镜的移动实现变焦，另外两个电机控制平面镜转向实现光斑位置的移动。设计了聚焦扫描算法，通过实验验证了该方法的实用性。 |
| 英文摘要: |
| A method of focusing and scanning measurement is proposed to solve the flexibility defects of measurement with single-point laser vibrometers. Three stepper motors are utilized to control the focusing and scanning; one of three stepper motors controls the moving of optical lens to realize zoom variable focal length, and the other two stepper motors control the plane mirror to move toward the light spots location. The test proves the practical value of the designed arithmetic of focusing and scanning. |
