Outline
Two types of fiber-optic pin have been developed for measuring shock wave physics characters in strong electromagnetic environment and low shock pressure experiments. One is the shock self-luminescene fiber-optic pin, and the other is the flash-gap fiber-optic pin. The physical mechanism of the fiber-optic pins is the quartz and the argon (or air) gap can luminesce under shock compressed. The dynamic time response character of the fiber-optic pins have been tested under shock loading. The response time of self-luminescene fiber-optic pin signals are less than 3 ns, which obtained in experiments that shock pressure was higher than 70 GPa. The response time of flash-gap fiber-optic pin signals are between 2 ns and 7 ns under 10~30 GPa shock pressures.
