Abstract: Based Doppler shifted effect and self-mixing effect, an all-fiber photonic Doppler velocimetry was developed to solve the problem when VISAR was used to measure high-acceleration flyers, the Doppler-shifted signals often lost. Used this system to measure the laser-driven flyer's velocity at different energies. The results showed that the PDV system have a high measuring success rate, high react speed, and the calculated results is good. Compared with VISAR and F-P interference velocimetries, the PDV have many advantages such as operation more simple, high measuring success rate, easy for carrying. This system was suitable to measure the velocities of small flyers and small scale detonation which had speeds between hundreds and thousands meters per second, also the usual detonation speed measurement.
