Paper Abstract

In this work we employed two-wave optical pyrometer to record characteristics of light emission and brightness temperature in shock and detonation waves. Light is transmitted to photoelectronic multiplier over a fiber light conductor with its end located in the immediate neighborhood of a light source. Error in brightness temperature determination does not exceed value (Delta) T equals +/- 5%. Limit space resolution of the technique is X equals 50 micrometers at brightness temperature T equals 2500 K. Time resolution reaches value (Delta) t equals 1 ns. The paper presents data on character of luminescence and brightness temperature of detonation front in plastic high-explosive, nitromethane, mixture of trinitrotoluol with RDX, and HE basing on TATB. This has been demonstrated that existence of micropores with air in solid HE because of intensive light flashes can exceed integral brightness of detonation front luminescence significantly.
