Paper Abstract

The ULTRANAC Ultra-High Speed Framing and Streak Camera System, from Imco Electro-Optics Limited of England was first presented to the market at the 19th ICHSPP held in Cambridge, England, in 1990. It was the world's first fully computerized image converter camera and is capable of remote programming at framing speeds up to 20 million fps and streak speeds up to 1 nS/mm. The delay, exposure, interframe and output trigger times can be independently programmed within any one sequence. Increased spatial resolution is obtained by generating a series of static frames during the exposure period as opposed to the previously utilized sine wave shuttering technique. The first ULTRANAC was supplied to Japan, through the parent company, NAC, in 1991. Since then, more than 40 cameras have been installed world-wide. The range of applications is many and varied covering impact studies, shock wave research, high voltage discharge, ballistics, detonics, laser and plasma effects, combustion and injection research, nuclear and particle studies, crack propagation and ink jet printer development among many others. This paper attempts to present the results obtained from such tests. It will describe the methods of recording the images, both film and electronically, and recent advances in cooled CCD image technology and associated software analysis programs.
