Abstract

Conventional flash exposure systems used in conjunction with a moving hotoreceptor require high voltage ower supplies with resulting high costs prevent image blur. A higher photoreceptor speed requires a shorter exposure pulse. This proposal uses a low voltage power supply to produce a long flash pulse. A mechanical focal plane shutter is used next to the image or object instead of the shutter near the lens.
