Lance Richard Leclair has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Single Aperture Multiple Optical Waveguide Transceiver
    Publication number: 20120227263
    Abstract: A single-aperture, multi-axial transceiver is provided that is particularly useful in a LIDAR system for detecting low velocities at increased ranges. The system is particularly useful in systems that measure very low velocities and very short distances as well as to provide an operating range of hundreds of meters. The transceiver uses closely spaced waveguides placed near the focal point of a single objective to form input and detector apertures.
    Type: Application

  • Single aperture multiple optical waveguide transceiver
    Patent number: 8190030
    Abstract: A single-aperture, multi-axial transceiver is provided that is particularly useful in a LIDAR system for detecting low velocities at increased ranges. The system is particularly useful in systems that are required to measure very low velocities and very short distances as well as to provide an operating range of hundreds of meters. The transceiver uses closely spaced waveguides placed near the focal point of a single objective 8 to form input and detector apertures. Preferably the input and detector apertures are spaced from each other by less than about 80 ?m. In an embodiment using light with a wavelength of 1550 nm, the spacing is preferably about 30 ?m.
