Abstract
We describe and demonstrate a fiber-optic laser Doppler velocity senso r which is based on interferometric processing of a wavelength encoded signal, The range of the fiberoptic velocimeter is scalable from less than 1 mm/s up to 1000 m/s through changes in the optical path imbala nce in the fiber-optic interferometer. A dynamic velocity resolution o f <80 mu m/s/root Hz is demonstrated.
