摘要： A lidar system includes one or more light sources configured to generate a first beam of light and a second beam of light, a scanner configured to scan the first and second beams of light across a field of regard of the lidar system, and a receiver configured to detect the first beam of light and the second beam of light scattered by one or more remote targets. The scanner includes a rotatable polygon mirror that includes multiple reflective surfaces angularly offset from one another along a periphery of the polygon mirror, the reflective surfaces configured to reflect the first and second beams of light to produce a series of scan lines as the polygon mirror rotates. The scanner also includes a pivotable scan mirror configured to (i) reflect the first and second beams of light and (ii) pivot to distribute the scan lines across the field of regard.

摘要： A display system may display image frames. The system may include a scanning mirror and an array of staggered light emitting elements. The light emitting elements may emit image light and collimating optics may direct the light at the scanning mirror, which reflects the image light while rotating about an axis. Control circuitry may selectively activate the light emitting elements across tangential and sagittal axes of the image frame while controlling the scanning mirror to scan across the sagittal axis.

摘要： A light scanning device includes: a first semiconductor laser 44a that emits a light beam L1; a polygonal mirror 42 that deflects the light beam L1; a reflective mirror 64a that reflects the light beam L1 deflected by the polygonal mirror 42 and causes the light beam L1 to enter a photosensitive drum 13; and a BD sensor 72 that detects the light beam L1 deflected by the polygonal mirror 42. The light scanning device scans the photosensitive drum 13 with the light beam L1 and set scanning timing of the photosensitive drum 13 using the light beam L1 based on detection timing of the light beam L1 using the BD sensor 72. The BD sensor 72 is arranged in the position farther from the polygonal mirror 42 than the last reflective mirror 64a that reflects the light beam L1 immediately before entering the photosensitive drum 13 and arranged inside a scanning angle range α of the light beam L1 corresponding to an effective scan area of the photosensitive drum 13.

摘要： An optical scanning apparatus includes: an array of optical emitters to provide a plurality of optical beams; a plurality of corresponding microlenses to receive the optical beams; and a variable collimator to receive the plurality of optical beams from the microlenses. The microlenses and variable collimator are arranged to decouple the illumination spot size of the optical beams from the illumination spot separation of the optical beams such that the illumination spot size and the illumination spot separation at a scanning surface are independently controllable.
