To investigate the response of fiber probe on explosion loading and the response character under impacting action, the detonation experiments of the TNTRDX-Al explosive and the composite B explosive were developed. The 0.063 5 mm fiber probe with concentrating collimation convex in the front-end and the 1 mm fiber probe without concentrating collimation convex were adopted separately to determinate the transmission velocity of the chemical propagating reaction. Both of them could determine the detonation velocity of explosives ~7 000 m/s and the uncertainty of measurement 2%. The fiber reaction signals under shock were recorded using the fiber probe without concentrating collimation convex. And the black-body radiation phenomenon was validated under the high temperature and high pressure produced by strong impact.
