摘要
根据望远镜的工作原理,对变焦距光学镜头的变焦运动进行了定性分析,并且根据理想光 学系统的物像关系式推导出该镜头运动镜组的运动方程。该连续变焦控制的实验装置包括步进电机、电机驱动器以及控制平台,其控制程序用Visual C++编写。实验表明,该方法能方便地实现连续变焦距光学镜头的变焦控制。
The zooming movement of zoom optical lens is qualitatively analyzed according to operating principle of telescope. The movement equation for the lens moving lens set is derived according to the object-image relationship of the ideal optical system. The experimental setup controlled by the continuous zoom consists of a step motor, motor actuator and a control platform, and the control program is compiled with Visual C++. The experiments show that the method can be convenient to realize zooming control of the continuous zoom optical lens.
