Abstract: A system and method for providing a dynamic region of interest in a lidar system can include scanning a light beam over a field of view to capture a first lidar image, identifying a first object within the captured first lidar image, selecting a first region of interest within the field of view that contains at least a portion of the identified first object, and capturing a second lidar image, where capturing the second lidar image includes scanning the light beam over the first region of interest at a first spatial sampling resolution, and scanning the light beam over the field of view outside of the first region of interest at a second spatial sampling resolution, wherein the second sampling resolution is different the first spatial sampling resolution.

Abstract: In an optical detection system, received light can be concentrated and presented to a single-pixel photodetector (or an array of relatively few photodetectors). Concentration of received light can be performed by curved concentrator such as a continuously-curved or faceted reflector. A portion or an entirety of the detector might be blinded (e.g., desensitized) by bright interferers such as the sun. An electro-optic shutter such as a liquid crystal (LC) structure can be used to selectively transmit or mask-off portions of the received light. For example, an LC structure can have regions of selectable opacity for a specified polarization of incident light. The LC structure can be controlled to render certain region opaque, such as to suppress interference from unwanted interferers such as the sun, bright lights, or unwanted reflections. An LC structure can also be used to implement a scanned transmit/receive technique.

Abstract: A lidar system can be provided for measuring a clearance of overhead infrastructure, such as a bridge or overpass. The lidar system can alert a vehicle driver or automatically brake the vehicle if the available clearance is smaller than a height of the vehicle. The lidar system can emit rays of light over a range of angles towards a target region where the rays of light can have a vertical span. The lidar system can then receive rays of light reflected or scattered from the target region and can determine a distance traveled by the rays of light by determining a round trip travel time of the rays. A clearance of the overhead infrastructure can then be determined using geometric relationships.

Abstract: Remote keyless entry (RKE) systems and devices are described. The RKE devices include one or more passive radios that respond to an interrogation signal from an interrogating device such as a vehicle. The passive radio sends a responsive signal that can include a decaying portion representing a ringdown signal. The passive radio includes a SAW resonator in some situations.

Abstract: Optical systems can emit train(s) of light pulses onto objects to derive a distance between the light source and the object. Achieving meter or centimeter resolution may require very short light pulses. It is not trivial to design a circuit that can generate narrow current pulses for driving a diode that emits the light pulses. An improved driver circuit has a pre-charge path comprising one or more inductive elements and a fire path comprising the diode. Switches in the driver circuit are controlled with predefined states during different intervals to pre-charge current in the one or more inductive elements prior to flowing current through the fire path to pulse the diode.

Abstract: Techniques are described to for improving a resolution of a light detection and ranging (LIDAR) system. A receiver circuit of a LIDAR system can sample a reflection signal from an object in response to a transmitted light pulse. A controller can determine a curve fit to the received samples and, based on a peak value of the curve fit, determine a precise location of the object.

Abstract: Improved flash light detection and ranging (also referred to herein as “flash LIDAR”) systems and methods for determining the distance to a target object disposed in a field-of-view. A flash LIDAR system can include an array of illuminators, an array of light detectors, and a signal processor/controller, as well as have a field-of-view in which a target object may be disposed. The flash LIDAR system can effectively divide the field-of-view into a plurality of segments, and each illuminator in the illuminator array can be made to correspond to a specific segment of the field-of-view. The flash LIDAR system can also effectively divide the light detector array into a plurality of subsets of light detectors. Like the respective illuminators in the illuminator array, each subset of light detectors in the light detector array can be made to correspond to a specific segment of the field-of-view.
