Abstract: An optical displacement sensor is disclosed that provides a high signal-to-noise ratio output signal without some of the disadvantages for doing so in the prior art. An embodiment of the present invention directs a light beam toward a Fabry-Perot interferometer and detects both the reflected and transmitted optical beams that result from interaction with the Fabry-Perot interferometer. Signal processing techniques are applied to signals based on both the reflected and transmitted beams, resulting in higher signal strength and/or reduced noise in the resulting output signal.

Abstract: An apparatus and method for discriminating a directional component of a propagating pressure wave using an array of operatively-coupled displacement sensors are disclosed. In accordance with the illustrative embodiment, each displacement sensor in the array comprises two parallel layers, at least one of which is movable. The output signal of each displacement sensor is based on the separation of the layers. The displacement sensors are operatively-coupled through a compressible fluid such that the response of one of the sensors to an input can cause an output signal in at least one of the other sensors. The operative-coupling of the displacement sensors amplifies relative phase information between their respective output signals, which results in improved directionality. Some embodiments of the present invention are particularly well-suited for use in microphones.

Abstract: A gravimeter for detecting a gravity difference between two points is disclosed. The gravimeter comprises an interferometric arrangement wherein the length of a reference arm is dependent upon the gravity local to a first accelerometer and the length of a sample arm is dependent upon the gravity local to a second accelerometer. A pair of photodetectors that operate in complimentary fashion provide electrical signals based on a first signal conveyed by the reference arm and a second signal conveyed by the sample arm. A change in the differential gravity between the two points induces equal and opposite changes to the magnitudes of the two electrical signals.

Abstract: An optical displacement sensor is disclosed comprising a beam splitter having two optically coupled and mechanically coupled optically resonant cavities. The respective cavity lengths of the optically resonant cavities are functions of an environmental stimulus. By virtue of the optically coupled optically resonant cavities, the output of the beam splitter is less sensitive to input wavelength variation yet retains high sensitivity to the environmental stimulus.
