  • Method and system for optical fiber sensing
    Patent number: 11920963
    Abstract: A method of optical sensing comprises coupling an excitation optical signal into a first optical fiber to induce Rayleigh backscattering, thereby providing a backscattered signal. The backscattered signal is optically amplified in the first optical fiber, thereby providing an amplified backscattered signal. The amplified backscattered signal is coupled into a second optical fiber and is optically re-amplifying in the second optical fiber.
    Type: Grant
    Filed: December 12, 2019
    Date of Patent: March 5, 2024
    Assignee: Ariel Scientific Innovations Ltd.
    Inventors: Shmuel Sternklar, Egor Liokumovitch
  • Method and system for interferometry
    Patent number: 11333484
    Abstract: An interferometer system comprises a sample interferometer arm for guiding a first wave to a sample, and receiving a reflected wave from the sample and a phase amplifier for amplifying a phase shift of the reflected wave, to provide phase-shift-amplified intermediate wave. The interferometer system can also comprise an additional interferometer arm for guiding an additional wave to combine with the intermediate wave, to provide an output wave, and a detector for detecting the output wave.
