摘要
锁相环技术在电子技术领域中有着广泛的应用，其功能主要是用来跟踪信号和进行频率合成．本文介绍了锁相环技术在狭缝式高速摄影仪中的实现，即使用锁相环技术控制直流电机，从而使该类设备的控制从传统的完全使用模拟器件提高到使用数字器件的水平．
The Phase Lock Loop(PLL) technology has extensive uses in electronic field. It can be used to trace signal and to compose frequency. This paper introduced the realization of PLL on high camera——to control electric motor, which makes electric motor control technique turn from using analog device completely to digital device in this equipment.
