Abstract

This paper deals with a new type of control system for a continuous access rotating-mirror high speed camera. New design of most circuits and the fast-open shutter of the system has been adopted. The control system has characteristics of stability and reliability, accurate controlling, and rather high integration and automation. The system has been used for Model ZDF-180 rotating-mirror high speed camera, with satisfied operational results. In the study of high speed phenomena, such as explosions and discharges, etc., the continuous access rotating-mirror high speed camera is an indispensable photographic recorder. With wide applications of high speed photographic technique, the environments where this camera is used are more complicated so the following performances of the controlling sys-tem are required to be further raised: 1. the control accuracy of the system (synchronous accuracy and measuring accuracy of photographic frequency); 2. the opening speed of the fast-open shutter, so as to guarantee enough effective recording time; 3. the ability of anti-interference. The control system is made to be more stable and reliable; 4. the improvement of performances of the system by adopting new components, so it is more handy to be operated. In order to meet the requirements mentioned above, a control system has been designed. It consists of three parts: the main control, the fast-open shutter and its control, motor control driven by the rotating-mirror. The principle block diagram and working process of the each part are introduced separately as follows:
