Patent number: 11933901Abstract: A light detection and ranging (lidar) system for a vehicle may include a receiver layer, a transmitter layer coupled to the receiver layer through an adhesive layer in a first direction, and one or more optics. The transmitter layer may receive, at a first side of the transmitter layer, a transmit signal from a laser source, and transmit the transmit signal through the one or more optics. The receiver layer may receive, through the one or more optics, a return signal reflected by an object in an environment of the vehicle, and output the return signal at a first side of the receiver layer. The first side of the transmitter layer and the first side of the receiver layer may be apart from and parallel to each other in a second direction crossing the first direction.Type: GrantFiled: September 14, 2022Date of Patent: March 19, 2024Assignee: AURORA OPERATIONS, INC.Inventors: Zeb Barber, Stefan Heinemann, Randy Reibel

Publication number: 20070171407Abstract: Techniques for detecting optical spectral properties of a target are described. The technique includes providing an optical carrier which has an optical frequency bandwidth which is narrow compared to the width of the narrowest spectral feature of the target to be determined. This optical carrier is then electro-optically modulated with an RF frequency chirp, creating an optical chirp probe beam with a frequency chirped optical spectrum having upper and lower frequency chirped sidebands that have amplitudes sufficient to be detected at a detector. The sidebands are frequency bands arranged symmetrically around the optical carrier frequency. The attributes of a sideband include a start frequency, bandwidth and chirp rate. A probe beam is generated with the sidebands and directed onto a target having a physical property with optical frequency dependence. An optical response signal resulting from an interaction between the probe beam and the target is detected.Type: ApplicationFiled: April 14, 2006Publication date: July 26, 2007Inventors: Zachary Cole, Randy Reibel, Krishna Rupavatharam, William Babbitt, Kristian Merkel, Tiejun Chang
