摘要：

A new velocity interferometric system called all-fiber white-light velocity interferometric system of any reflector (FVISAR) was demonstrated. The important development of the FVISAR were discussed, such as the perfect space-interference property and the potential to work with very short coherence length light source even if white-light, in comparison with the conventional velocity interferometric system of any reflector (VISAR) which consists of complicated discrete optical elements. The key points in designing a FVISAR were described, and an experimental FVISAR system with very low source power was reported. Preliminary tests to the FVISAR were conducted using the Hopkinson Bar system. The results show that the observed free-surface velocities of LY12 aluminum samples are in good agreement with theoretical values by impedance match.
