Latest Patents

Bibby's latest patents focus on advanced methods of measuring temperature using optical fibers. The first patent describes a method that involves launching input pulses of light at two different wavelengths into a temperature sensing element, which is an elongate optical fiber. This method includes passing Raman scattered light from the element to intensity detectors and processing the output signals to provide accurate temperature measurements. A known position along the optical fiber is maintained at a specific temperature to serve as a reference for deriving measurements at other positions.

The second patent outlines a technique for measuring temperature by launching light pulses into an optical fiber and determining the temperature at various positions based on the intensity of scattered light. This method can utilize either the same or different wavelengths for the input pulses. The scattered light can be Raman or Brillouin scattered, and the temperature is derived from the ratio of intensities at specific wavenumber shifts or from the intensities of Stokes and anti-Stokes shifted Brillouin backscattered light.
