Text: Berkovic is an article published in 2012, entitled “Optical Methods for Distance and Displacement Case: 20-2070 Document: 51 Page: 6 Filed: 02/04/2022 6 QUANERGY SYSTEMS, INC. v. VELODYNE LIDAR USA, INC. Measurements.” J.A. 6985–7007. It reviews various techniques for measuring distance to objects, including triangulation and time-of-flight sensing. See J.A. 6985. According to Berkovic, triangulation is “a procedure in which a distance or position is determined from considerations based on the geometries of similar triangles.” J.A. 6990. Berkovic reports that commercially available triangulation sensors “are generally applicable for distance measurements in ranges of approximately 10 mm to 1 m.” J.A. 6991–92. Meanwhile, problems arise when using laser time-of-flight sensors to obtain accurate measurements at distances shorter than tens of meters. 1 J.A. 6993.
