Abstract: An electronic device includes a first laser source (101a) configured to project a first laser beam (107a), and a second laser source (101b) configured to project a second laser beam (107b) in alignment with the first laser beam in a first direction but at an angle with respect to the first laser beam in a second direction. A mirror apparatus (110) is positioned so as to reflect the first and second laser beams. Control circuitry (130) is configured to control the mirror apparatus to simultaneously reflect the first and second laser beams in a first scan pattern to form an first image, the first image formed from the first scan pattern having a number of scan lines greater than two times a horizontal resonance frequency at which the mirror apparatus oscillates divided by a desired frame rate of the first image.
