Abstract
Display systems, such as near eye display systems or wearable heads up displays, may include a laser projection system having an optical engine and an optical scanner. Light output by the optical engine may be directed into the optical scanner as two angularly separated laser light beams. The angularly separated laser light beams may overlap at an entrance pupil plane along a first dimension at a first scan mirror of the optical scanner, or at a location between the first scan mirror and an optical relay of the optical scanner. The angularly separated laser light beams may overlap at an exit pupil plane along the first dimension at a second scan mirror of the optical scanner or at an incoupler of the laser projection system.
