Some important effects of viewing a laser scanned display (LSD) on visual perception was investigated. LSDs could provide a highly bright

monochromatic image which could have particular effects on the visual system. Participants accommodation was measured while they viewed an image on either a laser-scanned or video-projected display. Furthermore

monochromatic displays may affect perception as a result of chromatic adaptation. Color vision of participants was also assessed before and after using the displays. Increased variability of the level of accommodation was found when using the laser-scanned display

but the magnitude of the effect was mediated by how fast elements of the display were moving. The biggest difference in accommodative variance was between a video display with slow-speed scanning and an equivalent laser-scanned display. Viewing of the laser-scanned display also led to measurable changes in color perception in some participants. The experimental results showed that viewing a laser-scanned display affect the accommodation response and color perception.
