Abstract
A SYSTEM has been developed which permits synchronous operation of stroboscopic light sources with certain commercial, optically compensated, and shuttered high-speed cameras. While the use of pulsed light sources for making high-speed motion pictures is not new, it is believed that this is the first successful synchronous system which combines the desirable features of one-microsecond flashlamp exposures with optical compensation of the blur caused by the continuously moving film in the high-speed camera. For this reason, the high-speed motion pictures which this system produces exceed in quality and definition those pictures taken previously. Up to 3,000 exposures per second can be made with presently available cameras.
