摘要： A LiDAR system includes a transmitter having a first and second laser emitter generating first and second optical beams and projecting the optical beams along a transmitter optical axis. A receiver includes an array of pixels positioned with respect to the receive optical axis such that light from the first optical beam reflected from an object forms a first image area and light from the second optical beam reflected by the object forms a second image area on the array of pixels such that an overlap region between the first image area and the second image area is formed based on a measurement range and on a relative position of the transmitter optical axis and the receive optical axis. A processor determines what pixels are in the overlap region from electrical signals generated by at least one pixel in the overlap region and generates a return pulse in response.

摘要： Disclosed herein are techniques relating to a light detection and ranging (LiDAR) system that includes a first optical array including a first active area, a second optical array including a second active area, wherein the first active area and the second active area are separated by a distance, and at least one optical component configured to laterally-shift a virtual image corresponding to at least one of the first optical array or the second optical array, thereby reducing a gap in a field of view (FOV) of the LiDAR system. The at least one optical component may be reflective, refractive, diffractive, or a combination of reflective, refractive, and/or diffractive. The at least one optical component may include one or more prisms and/or one or more mirrors. The optical arrays can be emitter arrays (e.g., lasers) or detector arrays (e.g., photodiodes). The techniques described herein can be used to combine more than two optical arrays.

摘要： In an optical emitter device, when point emitters are placed on the focal plane of a lens system, each individual point emitter will point to a specific free space angle depending on the position of the point emitter relative to the longitudinal central axis of the lens system. Point emitters comprising end-fire tapers combined with both a turning mirror and a micro-lens provide improved performance, because, unlike grating couplers, end-fire tapers enable uniform broadband operation with all possible polarization states. A turning mirror may be added to direct the light emission from the end-fire tapers to vertically upwards, which enables both a two-dimensional point emitter array and a more streamlined assembly process.
