Abstract
An optical element, which is arranged between a light source and a light deflector reflecting and two-dimensionally deflecting incident light, includes: a first region on which light from the light source is caused to be incident and which emits the light to the light deflector; and a second region which is different from the first region, on which light reflected and two-dimensionally deflected by the light deflector is incident, and which emits the light to an outside, and an optical surface having a different optical action is provided on at least one side of an incident side and an emission side of the first region and an incident side and an emission side of the second region.

An optical element being arranged between a light source and a light deflector reflecting and two-dimensionally deflecting incident light, the optical element comprising:
- a first region on which light from the light source is caused to be incident and which emits the light to the light deflector;
- and
- a second region which is different from the first region, on which light reflected and two-dimensionally deflected by the light deflector is incident, and which emits the light to an outside,
- wherein an optical surface having a different optical action is provided on at least one side of an incident side and an emission side of the first region and an incident side and an emission side of the second region.
