Latest Patents

One of his latest patents is titled "Brillouin distributed temperature sensing calibrated in-situ with Raman distributed temperature sensing." This invention involves methods and apparatus for distributed temperature sensing (DTS) along a single mode or multimode optical waveguide or fiber. It includes a calibration of initial Brillouin-based DTS measurements using Raman-based DTS measurements to enable accurate subsequent Brillouin-based DTS measurements. Such calibration may occur while the fiber is deployed in the environment where temperature is to be sensed, correcting influences on Brillouin scattered light from stress or strain along the fiber. Additionally, calibration may utilize one or more discrete temperature sensors to correct errors in both the Brillouin-based and Raman-based DTS measurements.

Another significant patent is for "Optical fiber cable for use in harsh environments." This invention describes a fiber optic cable that includes a core and a surrounding protective layer. The core consists of an inner tube containing one or more optical fibers, while the protective layer includes an outer tube over the inner tube and a layer of buffer material positioned between them. The buffer material maintains the inner tube centrally located within the outer tube and provides a mechanical link to prevent relative movement. The inner tube may be coated with a low hydrogen permeability material to minimize hydrogen entrance, and the filling material may be impregnated with a hydrogen absorbing/scavenging material.
