Publication number: 20240125906Abstract: Disclosed herein are optical systems (e.g., LiDAR systems) and methods with improved eye safety. In some embodiments, a system includes a first light emitter configured to illuminate a first field of view (FOV) using light emitted at a first wavelength and a second light emitter configured to illuminate a second FOV using light emitted at a second wavelength. The second FOV is wider than the first FOV, and the first FOV extends to a further distance from the system than the second FOV. The system also includes a sensor configured to detect reflections off of targets within the second FOV, and at least one processor configured to execute one or more machine executable instructions.Type: ApplicationFiled: February 22, 2022Publication date: April 18, 2024Applicant: Neural Propulsion Systems, Inc.Inventors: Daryoosh REJALY, Oguzhan TEKE, Daniel M.

Publication number: 20230333206Abstract: Disclosed herein are systems and methods for estimating target ranges, angles of arrival, and speed using optimization procedures. Target ranges are estimated by performing an optimization procedure to obtain a denoised signal, performing a correlation of a transmitted waveform and the denoised signal, and using a result of the correlation to determine an estimate of a distance between the sensor and at least one target. Target angles of arrival are estimated by determining ranges at which targets are located, and, for each range, constructing an array signal from samples of received echo signals, and using the array signal, performing another optimization procedure to estimate a respective angle of arrival for each target of the at least one target. Doppler shifts may also be estimated using another optimization procedure. Certain of the optimization procedures use atomic norm techniques.Type: ApplicationFiled: February 25, 2023Publication date: October 19, 2023Applicant: Neural Propulsion Systems, Inc.Inventors: Babak HASSIBI, Behrooz REZVANI

Publication number: 20230168359Abstract: Disclosed herein are systems, devices, and methods that may be used for autonomous driving and/or in autonomous vehicles. Some embodiments use an integrated wide-aperture multi-band radar subsystem and leverage the unique propagation properties of multiple bands and/or multiple sensor technologies to significantly improve detection and understanding of the scenery and, in particular, to see around corners to identify non-line-of-sight targets. In some embodiments, at least one processor of the system is capable of jointly processing return (reflected) signals in multiple bands to provide high accuracy in a variety of conditions (e.g., weather). The disclosed radar subsystem can be used alone or in conjunction with another sensing technology, such as, for example, LiDAR and/or cameras.Type: ApplicationFiled: January 27, 2023Publication date: June 1, 2023Applicant: Neural Propulsion Systems, Inc.Inventors: Behrooz REZVANI, Babak HASSIBI, Fredrik BRÄNNSTRÖM, Oguzhan TEKE

Publication number: 20210325537Abstract: Disclosed herein are multiple-input, multiple-output (MIMO) LiDAR systems in which the fields of view of multiple illuminators (e.g., lasers) overlap and/or fields of view of multiple detectors (e.g., photodiodes) overlap. Some embodiments provide for illuminators that transmit substantially white pulse sequences that are substantially uncorrelated with each other so that they can be distinguished from one another when detected by a single detector.Type: ApplicationFiled: June 28, 2021Publication date: October 21, 2021Applicant: Neural Propulsion Systems, Inc.Inventors: Babak HASSIBI, Behrooz REZVANI
