Latest Patents

Wielandt holds a patent for a "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. These components are configured with the first and second retroreflectors to form an interferometer. A change in the 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. He has 1 patent to his name.
