Abstract
This high speed, instantaneous multi-image recorder comprises a video camera, sensor unit and light projector. A frame memory is connected to the video camera, a flashtube is to the light projector, a retarder is to the sensor unit. The flashtube is connected to the retarder, and a monitor is connected to the frame memory. The video camera, sensor unit and light projected are placed as directed toward a moving object which is, for example, a golf club. When the golfer swings the club, the sensor unit detects the club, the light projector flashes, and the video camera picks up the golf ball and club head around the moment of impacting. Thus, the video camera catches many instantaneous poses within a frame. Many such images picked up in a signal frame of the video camera are displayed on the monitor screen for analysis.
