  • Patent number: 8520288
    Abstract: A method and apparatus for resonant gas phase optical phase modulation is disclosed. The method may include passing a laser beam longitudinally through a tube open to air at both ends and setting air inside the tube into resonant acoustic oscillation, thereby temporally modulating the refractive index of the air, which temporally modulates the optical phase of the laser beam.

  • Patent number: 5828626
    Abstract: A standing wave field is generated within a protected space, the standing wave field comprising a plurality of signals traveling along a plurality of propagation paths within the protected space, the propagation paths including reflections of the signals off of objects within the protected space. A change in a predetermined characteristic of the standing wave field is detected upon the changing of a physical characteristic of an object within said protected space, and an alarm signal is generated when said change in the standing wave field is greater than a predetermined threshold value.
