L. Fabiny et Ad. Kersey, INTERFEROMETRIC FIBEROPTIC DOPPLER-VELOCIMETER WITH HIGH-DYNAMIC RANGE, IEEE photonics technology letters, 9(1), 1997, pp. 79-81
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.
