ALEXANDRIA, Va., Jan. 28 -- United States Patent no. 12,535,583, issued on Jan. 27, was assigned to DUKE UNIVERSITY (Durham, N.C.).
"3D sensing depth camera" was invented by Joseph Izatt (Durham, N.C.), Ruobing Qian (Durham, N.C.) and Kevin Zhou (Durham, N.C.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A 3D sensing depth camera involves a time-frequency multiplexed frequency-modulated continuous wave (FMCW) LiDAR technique. A sample arm of such a system for 3D depth sensing includes a scanner for beam scanning in a first axis and a diffractive optical element for spectrally encoded scanning along a second axis. The sample arm can further include beam shaping optics such as a collimator and a lens. Process...
