Title:
SCANNING OPTICAL SYSTEM AND RADAR
Document Type and Number:
WIPO Patent Application WO/2014/168137
Kind Code:
A1
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, the scanning optical system and radar also being able to suppress changes in resolution while maintaining a wide range of view. A light beam emitted from a light source, after being reflected by a first mirror surface of a mirror unit, progresses along a rotational axis, is reflected by a second mirror surface, and is projected on the object while being scanned across the object along a scanning angle direction around a scanning angle center in correspondence with rotation of the mirror unit. The light beam radiated from a projection system is longer in a width scanning angle direction than in the scanning angle direction in the measurement range of the object, and satisfies the following equation. |θ1 - 90| × |α| ≤ 225 (1); θ1: angle (˚) of intersection between first mirror surface and second mirror surface, α: angle of rotation (˚; 1/2 of the scanning angle)
