ALEXANDRIA, Va., Aug. 12 -- United States Patent no. 12,386,045, issued on Aug. 12, was assigned to Apple Inc. (Cupertino, Calif.).
"Enhanced LiDAR measurements using chirp nonlinearities" was invented by Nurul Taimur Islam (Cupertino, Calif.), Helen H. Liang (Los Gatos, Calif.), Jack E. Graves (Sunnyvale, Calif.) and Malcolm J. Northcott (Santa Cruz, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A range sensing apparatus includes a modulator that applies a frequency chirp to a light source, causing a nonlinear variation in a frequency of an outgoing beam towards a target. A detector receives both a portion of the outgoing beam and a reflection of the outgoing beam from the target. A processor, which...
