英文摘要：

Aiming at problem of shock wave parameter detection and system reliability, a shock wave parameter detection system with self-check function is designed. Sensing probe uses self-illumination type probe coating optical fiber, the probe radiate light under high pressure and through high-speed photoelectric conversion and oscilloscope to record shock response signal, and realize shock wave parameter measurement. Coupling the laser pulse with the sensing channel, self-check of the whole system is realized by detecting the reflected pulse signal from the top end of metal film of the fiber probe. Design and implementation of film coating optical fiber probe, high speed photoelectric conversion circuit and semiconductor laser pulsed driving source is introduced in detail. The measurement of arrival time of the shock wave under TNT detonation driving is carried out, and experimental result indicates that the frontier of shock wave response signal of system is less than 5 ns and uncertainty of measurement is less than 3 ns, and the system provides a reliable and effective measurement method for shock wave parameter measurement in detonation physics and shock wave physics experiments.
