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.
