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.
