Use of Image Converter Tube for High-Speed Shutter Action

The equipment described provides a means for obtaining high-speed photographs while utilizing a continuous light source. The device may be pulsed once for "one-shot" exposures or repetitively for motion pictures or stroboscope applications. The heart of the equipment is an image converter tube such as the 1P25. Images are impressed on the photocathode and the tube is pulsed electrically for a duration equal to the exposure time desired. The image will then appear on the fluorescent screen and may be viewed directly or photographed.
