Paper Abstract

A repetitively pulsed broad band visible illumination system has been developed that is suitable for capturing images of high speed motion over sizable areas. At full pulse energy, a two lamp system can illuminate 60 square feet for movies at f/4 with 400 ASA color film and framing rates as high as 1700 fps. At reduced energy, for smaller area applications, the framing rate can be doubled. The short pulse length (4.5 microsecond(s) at full energy, 1.5 microsecond(s) at reduced energy) produces sharp images of high speed objects. This paper reports developments since the last presentation, including: (1) higher pulse repetition rates (a few kilohertz), (2) synchronization with high speed camera, (3) full scale burst of several thousand pulses, (4) characteristics of a compact demonstration system, and (5) demonstration of the ability of the short pulse to freeze motion.
