摘要： A laser radar includes: a laser, an optical transmission system, a 1-dimensional array of photo-detectors, an optical reception system, and an electronic control system. The laser emits a wavelength of light, and the optical transmission system shapes the light into a beam, and scans the beam along a fan of transmission light paths toward a target. The photo-detectors are capable of time-of-arrival measurements and are sensitive to the wavelength of light. The optical reception system collects the laser light reflected from the target along a fan of reception light paths. The electronic control system synchronizes the scan of the beam with a respective time-of-arrival measurement from each of the photo-detectors, and analyzes the time-of-arrival measurements. The system is configured for all of the transmission light paths and all of the reception light paths to lie in one plane, with all of the reception light paths intersecting with at least one of the transmission light paths.

摘要： A system and method include scanning a light detection and ranging (LIDAR) device through a range of orientations corresponding to a scanning zone while emitting light pulses from the LIDAR device. The method also includes receiving returning light pulses corresponding to the light pulses emitted from the LIDAR device and determining initial point cloud data based on time delays between emitting the light pulses and receiving the corresponding returning light pulses and the orientations of the LIDAR device. The initial point cloud data has an initial angular resolution. The method includes identifying, based on the initial point cloud data, a reflective feature in the scanning zone and determining an enhancement region and an enhanced angular resolution for a subsequent scan to provide a higher spatial resolution in at least a portion of subsequent point cloud data from the subsequent scan corresponding to the reflective feature.

摘要： The light source device includes a light emitting unit, a scanning unit, and a controller. In the light emitting unit, a plurality of light emitting elements is arranged along a first direction. The scanning unit scans light emitted from the plurality of light emitting elements along the second direction orthogonal to the first direction. The controller performs control to make the number of times of light emission of the first light emitting element group included in the plurality of light emitting elements larger than the number of times of light emission of the second light emitting element group not included in the first light emitting element group.

摘要： There is provided a time of flight sensor including a light source, a first pixel, a second pixel and a processor. The first pixel generates a first output signal without receiving reflected light from an external object illuminated by the light source. The second pixel generates a second output signal by receiving the reflected light from the external object illuminated by the light source. The processor calculates deviation compensation and deviation correction associated with temperature variation according to the first output signal to accordingly calibrate a distance calculated according to the second output signal.

摘要： A distance image acquisition apparatus includes a light source, an irradiation optical system, an imaging optical system, an imaging element, and a processing unit. The imaging element receives a light pulse output from the light source, reflected by an object, and passed through the imaging optical system on a light receiving surface. Each of a plurality of pixels on the light receiving surface includes a photodiode for generating charges by receiving light, and a charge accumulation portion for accumulating the charges generated in the photodiode. The processing unit commonly applies a control pattern to the plurality of pixels. The control pattern indicates a period in which the charges generated in the photodiode are accumulated in the charge accumulation portion. The processing unit acquires a distance image of the object based on an amount of charges generated in the photodiode and accumulated in the charge accumulation portion.
