Abstract A transient optical-electrical two-color pyrometer combined with optical-fibers was utilized to measure the temperature of shock relaxation in air-dusty explosive media in tiny transparent tubes. The external and internal diameters of the tubes are 3.0 mm and 1.5 mm, respectively. The explosives coated on the inner wall of the tubes are RDX/Al 91/9 with a loading density of 9 kg/m3 initiated by an electric spark. The temperature profiles versus time at various stages during the ignition-to-detonation transition processes of the media are given and discussed in detail. It is shown that there is a special temperature structure of the shock relaxation in multiphase reactive media different from that of a detonation in condensed high explosives.
