【 摘 要 】

In extensive research, damage to concrete panels by explosion is investigated. For detailed monitoring of particular phases of explosion, exploitation of a high-speed camera is intended. The paper presents testing of possibilities of lighting of the scene at detonation with explosive agents. Four alternatives of agents were tested - three varying amounts of aluminium powder and argon. Paper presents results of the tests - intensity of lighting for tested variants, delay between ignition of lighting agent and the main detonation, and evaluates convenience of tested explosive agents for illuminating of the scene captured by high-speed camera.
