HIGH SPEED SHUTTER SYSTEM
Abstract
A high speed camera system of recording 16 pictures, each exposed to the light from the object being viewed for 3 x 10 to the -7th power 10 to 3 x 10 to the -6th power seconds, was developed. The system is capable of doing this with an overall light gain so that considerably less light need illuminate the object under study than is required by high speed camera systems based on other physical laws. The experimental evidence furnished shows that photographic negatives having densities of 0.5 can be achieved with 1 microsecond exposure and 200 foot-candles illumination incident on the photocathode (150 watt projection lamp at 110 V) with readily available photographic film and camera optics.
