High-Speed Laser Imaging, Emission and Temperature Measurements of Explosions

Abstract

This presentation reports results of laser high brightness imaging, optical temperature, emission and heat flux measurements of explosive combustion products by explosives. High brightness images were recorded by a high-speed camera synchronized to the output of a Cu-vapor laser (510 nm, 12 kHz). Time resolved measurements of temperature and heat flux of fireballs produced by open-air detonation of explosives were made using three-color pyrometry and high-speed heat flux gauges, respectively. The emission measurements (visible region) were performed using a grating-based, modular, spectrograph.
