Abstract: The present disclosure relates to staggered arrays of individually addressable light-emitting elements for sweeping out angular ranges. One example device includes an astigmatic optical element. The device may also include an array of individually addressable light-emitting elements arranged to emit light towards the astigmatic optical element. The astigmatic optical element may be arranged to focus light emitted from each individually addressable light-emitting element to produce a substantially linear illumination pattern at a different corresponding scan angle within an angular range. The example device may further include a control system operable to sequentially activate the individually addressable light-emitting elements such that the substantially linear illumination pattern sweeps out the angular range. The individually addressable light-emitting elements may be staggered with respect to one another in the array such that the substantially linear illumination pattern sweeps out the angular range continuously.

Abstract: The present disclosure relates to curved arrays of individually addressable light-emitting elements for sweeping out angular ranges. One example device includes a curved optical element. The device may also include a curved array of individually addressable light-emitting elements arranged to emit light towards the curved optical element. A curvature of the curved array is substantially concentric to at least a portion of the circumference of the curved optical element. The curved optical element is arranged to focus light emitted from each individually addressable light-emitting element to produce a substantially linear illumination pattern at a different corresponding scan angle within an angular range. The device may further include a control system operable to sequentially activate the individually addressable light-emitting elements such that the substantially linear illumination pattern sweeps out the angular range.
