Abstract
A scanning optical system, includes a mirror unit equipped with a first mirror surface and a second mirror surface each of which inclines to a rotation axis; and a light projecting system which includes at least one light source to emit a light flux toward the first mirror surface. A light flux emitted from the light source is reflected on the first mirror surface of the mirror unit, thereafter, reflected on the second mirror surface, and then, projected so as to scan in a main scanning direction onto an object in accordance with rotation of the mirror unit, and in a case where a direction included in a main scanning plane is set to 0 degree, the light flux reflected on the second mirror surface is polarized in a range within an angle of ±30 degrees to the main scanning plane.

A scanning optical system, comprising:
- a mirror unit equipped with a first mirror surface and a second mirror surface each of which inclines to a rotation axis;
- and
- a light projecting system including at least one light source to emit a light flux toward the first mirror surface,
- wherein a light flux emitted from the light source is reflected on the first mirror surface of the mirror unit, thereafter, reflected on the second mirror surface, and then, projected so as to scan within a main scanning plane onto an object in accordance with rotation of the mirror unit, and
- wherein, where the main scanning plane is considered to be at 0 degree, the light flux reflected on the second mirror surface is polarized in a range within an angle of ±30 degrees to the main scanning plane.
