An Electronic Imaging System for the Aeroballistic Research Facility
Abstract
Until the present date, free-flight spark ranges have used conventional film technology for recording the position-attitude histories of the projectiles as they traversed the instrumented ranges. The purpose of this paper is to describe the plans for converting the existing film based camera system in the Aeroballistic Research Facility to an electronic imaging system based on modern charge coupled device (CCD) technology. The primary concern associated with this conversion has always been maintaining the facility's accuracy in measuring the projectile's position and attitude at each of the shadowgraph stations. This accuracy is directly related to the resolution of the CCD, i.e., number of pixels. Some other concerns were minimizing the facility down-time while the new imaging system is installed and maintaining a means of analyzing previous film exposures captured during the past 15 years of operation. The solution to these concerns is the development of a film reader system which also uses a CCD type camera to digitize the existing film....
