Publication number: 20190324461Abstract: A vehicular collision avoidance system comprising a system controller, pulsed laser transmitter, a number of independent ladar sensor units, a cabling infrastructure, internal memory, a scene processor, and a data communications port is presented herein. The described invention is capable of developing a 3-D scene, and object data for targets within the scene, from multiple ladar sensor units coupled to centralized LADAR-based Collision Avoidance System (CAS). Key LADAR elements are embedded within standard headlamp and taillight assemblies. Articulating LADAR sensors cover terrain coming into view around a curve, at the crest of a hill, or at the bottom of a dip. A central laser transmitter may be split into multiple optical outputs and guided through fibers to illuminate portions of the 360° field of view surrounding the vehicle. These fibers may also serve as amplifiers to increase the optical intensity provided by a single master laser.Type: ApplicationFiled: June 26, 2019Publication date: October 24, 2019Applicant: Continental Advanced Lidar Solutions US, LLC.Inventors: Patrick Gilliland, Roger Stettner, Laurent Heuhebaert, Bart M.

Patent number: 10401147Abstract: A dimensioning system that determines the dimensions and volume of an object by using a three-dimensional camera that measures the distance to every reflective point in its field of view with a single pulse of light. The distance is computed by the time of flight of the pulse to each camera pixel. The accuracy of the measurement is augmented by capture of the laser pulse shape in each camera pixel. The camera can be used on an assembly line to develop quality control data for manufactured objects or on a moving or stationary system that weighs as well as dimensions the objects. The device can also ascertain the minimum size of a box required to enclose an object.Type: GrantFiled: February 2, 2016Date of Patent: September 3, 2019Assignee: CONTINENTAL ADVANCED LIDAR SOLUTIONS US, LLCInventor: Roger Stettner

Patent number: 10126411Abstract: A beam steering capability is proposed for a ladar sensor operating with limited laser transmit power, as may be typical of an airborne or automotive application. The ladar system also makes use of optical gain elements in the receiver which act to increase the signal to noise ratio at the receiver when the laser transmit power available is restricted by power, size, and/or cost limitations. In one embodiment, the calibration of each pixel in the ladar sensor is provided for by an electrical amplifier array with a number of pixel amplifiers. Each pixel amplifier may be individually calibrated to a mating detector element so as to eliminate the variations in dark current and gain between all pixels in the detector array. A number of new detector array designs are described which may lower cost and improve performance, and new low cost and high performance packaging for the detector array, amplifier array, and readout integrated circuit is introduced.Type: GrantFiled: March 13, 2015Date of Patent: November 13, 2018Assignee: CONTINENTAL ADVANCED LIDAR SOLUTIONS US, LLC.Inventors: Patrick Gilliland, Roger Stettner
