Latest Patents

Marie-Noel Charasse holds 1 patent for her invention of an optical fiber sensor. This sensor utilizes the effect of variation in birefringence in a birefringent optical fiber, which changes in response to stress and temperature variations. The design features a linearly polarized, wide-spectrum source coupled to a polarizing-preserving single-mode optical fiber. Devices capable of inducing coupling points are distributed along the fiber, and a polarizer is positioned at a 45-degree angle to the fiber's neutral axes. The output radiation is analyzed using spectroscopy, such as a scanning Michelson interferometer, which aids in identifying devices subjected to stress. This technology can also be employed for simultaneous detection of stress and temperature.
