摘要
:针对实现系统变焦的传统机械方法 ,提出了以微处理机技术取代凸轮传动从而实现系统变焦的方法。这种方法的原理是利用微处理机、步进电机产生指令控制 ,经过较为简单的传动链后完成变焦要求。通过实验调试 ,证明这种电子学方法能够较好地完成变焦并达到精度要求 ,是一种可行的方法。
It is presented that a new method to realize zoom which using microprocessor instead of the cam transmission system. Utilizing microprocessor and stepping motor to produce commands, and after simple gearing, it can fulfill zoom of system. It can be proved through experiments that this method of electronics has advantages of accomplishing zoom, achieving precision, and feasible.
