This is a system based on a Motorola MC68HC11 micro controller. It was designed to synchronize the electronic capture of images of high-speed events or events that occur for only short instants. The microcontroller is interfaced with the electronics of an event detector which is based on a light-beam. When this light-beam is interrupted, the micro controller reacts by providing synchronized signals to a video camera, a strobe, and a frame-grabber to capture the image of the high-speed event. The system includes a programmable time delay that allows the images to be captured from approx. 80 µs to 400 ms after the light-beam has been interrupted. Design details are available in this link:
