Latest Patents
One of his latest patents is titled "Leaf-spring optical seismometer using fringe signals for seismic measurements." This invention discloses methods, structures, devices, and systems for implementing optical seismometers that detect seismic information based on optical interferometry. The device includes a first retroreflector attached to a mass of a seismometer and a second retroreflector attached to a member of the frame of the seismometer. The frame is structured to suspend the mass, and optical components are attached to the member of the frame, configured with the retroreflectors to form an interferometer. A change in position of the mass is identified by detecting a change in the optical path of a light beam generated by a light energy source transmitted to the interferometer.
Another notable patent is "Resolving quadrature fringes of interferometer signals in real time." This patent describes techniques and devices for digitally resolving quadrature fringe signals from interferometers, such as optical interferometers and interferometer-based sensing devices. In this implementation, two quadrature fringe signals from an interferometer are sampled to obtain digital data samples. These samples are used to perform linear least square fitting to establish coefficients for an ellipse traced by the two quadrature fringe signals as the phase difference changes. This digital processing allows for real-time processing of the signals.
