High-speed Camera Pixel Analysis for Simultaneous Temperature and Detonation Velocity Imaging

The Army Research Laboratory Research Associateship Program (ARL-RAP) offers a research opportunity focused on high-speed camera pixel analysis for simultaneous temperature and detonation velocity imaging. This research position is located at Aberdeen Proving Ground in Maryland at the U.S. Army Research Laboratory (ARL). The project involves decomposing high-speed color movies (up to 1M fps) into their blue, green, and red matrix components, using relative intensities to create temperature 'movies' of detonation events. These temperature movies are then used to calculate the velocity of detonation fronts and fireball expansion velocities for explosions. This work represents the first time that simultaneous imaging of temperature and shock velocity has been attempted, building on imaging techniques developed at ARL for single-camera imaging pyrometry. The research aligns with ARL's core competency in Ballistics Sciences, focused on gaining greater understanding and discovery of mechanisms and generating concepts and emerging technologies that support lethality and protection systems. The program is designed to significantly increase the involvement of creative and highly trained scientists and engineers from academia and industry in scientific and technical areas of interest and relevance to the Army.
