  • Phase-front-modulation sensor
    Patent number: 10495508
    Abstract: A sensor is provided. The sensor includes at least one optical waveguide and an optical reflector. The optical reflector is optically coupled to the at least one optical waveguide and includes a first portion and a second portion. The first portion is configured to reflect a first portion of light back to the at least one optical waveguide. The second portion is configured to reflect a second portion of light back to the at least one optical waveguide. The reflected second portion of the light differs in phase from the reflected first portion of the light by a phase difference that is not substantially equal to an integer multiple of ? when the second portion of the optical reflector is in an equilibrium position in absence of the perturbation.
    Type: Grant
