A new type micro-computer controlled all digital system of synchronous intermittent pin registered high speed camera

This paper introduces a new design method of synchronous intermittent pin registered high speed camera. The synchronous control system is a micro-computer controlled all digital frequency and phase detecting system. Speed-adjusting and phase-locking synchronous technology, no-overshot control technology, compound control technology and feedback data forecast technology are adopted in this system, and this has made the system gain high synchronous precision under wide frequency, obvious power voltage and load undulating; at the same time, the course of the start-up and frequency switch is very smooth. The paper describes the design of the system hardware and software, and at last, gives the application results.
