WANG Rong bo, WU Ting lie, WANG Gui chao, TIAN Jian hua, HE Li hua (Institute of Fluid Physics, China Academy of Engineering Physics, Mianyang 621900, Sichuan, China)  
A fast rise time fiber optical pin has been developed for measuring shock wave velocity, flyer velocity etc in special environment. The pin consists of a graded index optical fiber(one end coated with metal) and a metal capillary. The intrinsic rise time of signals obtained from detonation experiments, flyer experiments and shock wave experiments is less than one nanosecond, indicating such a pin is reliable and high time resolved for measurement.
