  • Method and system of compensating for signal artifacts in a fiber-optic sensing system
    Patent number: 5300769
    Abstract: A method and system for controlling the intervals during which light signals are sampled in a fiber-optic sensing system compensates for signal artifacts that are caused by movement of the fiber-optic waveguide during the sampling. The method and system sample the light signals at intervals that are shorter than the intervals during which displacement of the optical waveguide occurs in normal use. The short-sampling intervals result in the individual sampling of different wavelengths of light being exposed to the same changes in transmission characteristics of the optical waveguide which causes signal artifacts. Accordingly, when subsequent processing of the collected signals occurs, the effects of the signal artifacts are compensated for.
