Synchronizing A Stroboscope With A Video Camera
Abstract
Circuit synchronizes flash of light from stroboscope with frame and field periods of video camera. Sync stripper sends vertical-synchronization signal to delay generator, which generates trigger signal. Flashlamp power supply accepts delayed trigger signal and sends pulse of power to flash lamp. Designed for use in making short-exposure images that "freeze" flow in wind tunnel. Also used for making longer-exposure images obtained by use of continuous intense illumination.
