Abstract: On the basis of traditional velocity interferometer, a fiber velocity interferometer system for any reflector (FVISAR) with wide spectrum laser is illustrated. The important properties of the FVISAR are ideal space interference and convenient delay-time setup. Preliminary tests of FVISAR using Hopkinson Bar system shows that the FVISAR works well for low velocity measurement. -
