Latest Patents
Bettini holds a patent for a multiple-point temperature sensor using optic fibers. This sensor operates on the principle of birefringence variation in a birefringent optic fiber as a function of temperature. The design incorporates a plane polarized, wide spectrum source coupled to a monomode optic fiber, ensuring the preservation of polarization along one of the neutral axes. Weak coupling points are distributed along the fiber, and a polarizer is positioned at 45 degrees to the neutral axes at the output. The output radiation is analyzed using spectroscopy, such as in a Michelson interferometer, which is capable of being swept and associated with a detector. The shifts in the interferometer are used to measure temperature deviations.
