Abstract: Scanning optical system, comprising a rotatable mirror unit including first and second mirror surfaces each inclining relative to a rotation axis, and a light projecting system including a light source which emits light flux toward an object through the mirror unit. The light flux is reflected on the first mirror surface, then to the second mirror surface, and projected so as to scan on the object correspondingly to rotation of the mirror unit. The mirror unit includes multiples pairs of the first and second mirror surfaces, and the respective intersection angles of the multiples pairs are different from each other. In one rotation of the mirror unit, light flux emitted from the light source is reflected on the second mirror surfaces, and is projected sequentially, thereby to scan a measurement range in which the object is measured. Length in a sub scanning direction of the light flux and intersection angles of the multiples pairs correspond to length in a sub scanning direction of the measurement range.

Abstract: The present invention provides a scanning optical system and radar that can suppress longitudinal distortion and spot rotation of a spot light radiated on an object. A light flux emitted from a light source is reflected on a first mirror surface of a mirror unit, then, proceeds to a second mirror surface, further is reflected on the second mirror surface, and is projected so as to scan on an object correspondingly to rotation of the mirror unit. The light flux emitted from the light projecting system is made longer in a sub scanning angle direction than in a scanning angle direction in a measurement range of the object and satisfies the following conditional expression, |·1−90|×|·|·255 . . . (1); in the expression, ˜1 is an intersection angle (°) between the first mirror surface and the second mirror surface, and · is a rotation angle (°).
