ABSTRACT:
A disclosed optical scanning device scans an object scanning surface with a light beam projected from a light source and traveling through an optical system. The optical scanning device includes a liquid crystal element configured to modulate a phase. The liquid crystal element is driven by electric signals and provided on a light path between the light source and the object scanning surface. The liquid crystal element generates different power components in a main scanning direction and a sub scanning direction under temperature variations.
