Abstract: Disclosed herein are light detection and ranging (LiDAR) systems and methods of using them. In some embodiments, a LiDAR system comprises an array of optical components and at least one processor coupled to it. The array comprises n1 illuminators configured to illuminate a point in space, and n2 detectors configured to observe the point in space, wherein n1×n2>2 and the illuminators and n2 detectors are situated in a non-collinear arrangement. The at least one processor is configured to determine a first time-of-flight set corresponding to a first location of the LiDAR system at a first time; determine a second time-of-flight set corresponding to a second location of the LiDAR system at a second time; and solve an optimization problem to estimate a position of the target, wherein the optimization problem minimizes a cost function that takes into account the first time-of-flight set and the second time-of-flight set.

Abstract: 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.

Abstract: 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.
