Abstract
Optical apparatus includes a plurality of emitters arranged in a row and configured to emit respective beams of optical radiation. Projection optics, which are configured to project the beams toward a target, include first cylindrical lenses, which have respective, mutually-parallel first cylinder axes and are aligned respectively with the emitters in the row so as to receive and focus the respective beams in a first dimension, and a second cylindrical lens, which has a second cylinder axis perpendicular to the first cylinder axes and is positioned to receive and focus all of the beams in a second dimension, perpendicular to the first dimension. A scan driver is configured to shift the second cylindrical lens in a direction perpendicular to the second cylinder axis so as to scan the beams across the target.
