A laser projection system including a system controller, a visible light source, and a light disrupting element is provided. The visible light source includes at least one laser and the laser projection system is programmed to scan a scanned optical signal of the visible light source across a plurality of image pixels. The scanned optical signal comprises a low spatial frequency beam and a high spatial frequency beam, and the low spatial frequency beam generates a low spatial frequency image having spatial frequencies below a spatial frequency threshold, the high spatial frequency beam generates a high spatial frequency image having spatial frequencies that are above the spatial frequency threshold, and the scanned laser image is a sum of the high spatial frequency image and the low spatial frequency image. The low spatial frequency beam is altered by an out of focus light disrupting element.
