    摘要： 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 (°).

    摘要： A LIDAR unit includes: an LD driver, a laser diode, and a scanner corresponding to an emission unit; a photo detector, a current/voltage conversion circuit, a A/D converter and an valuable segmenter that correspond to a light receiving unit; a landmark position prediction unit and landmark map acquisition unit that acquire position information indicating the position of a landmark on a map; and a synchronization controller that generates a valuable pulse trigger signal and a segment extraction signal. Based on a predicted current vehicle position value and the position of the landmark on the map, the landmark position prediction unit determines a predicted angular range of the landmark. The synchronization controller generates the valuable pulse trigger signal and the segment extraction signal such that the scan density of the light pulse is higher in the predicted angular range than the scan density of the light pulse in the other range.

    摘要： The information processing device includes a plurality of light transmission/reception units and an information processing unit. Each of the light transmission/reception unit includes an emission unit which emits a light, a scanning unit which scans the light emitted by the emission unit, and a light receiving unit which receives the light reflected by an object. The information processing unit obtains at least one of a distance to the object and an angle of the object based on light receiving results of the light receiving units. Each of the scanning units is arranged at a position where there is a direction in which the light scanned by the scanning unit is blocked by a vehicle itself, and scans the light omnidirectionally in a horizontal direction in a manner shared by the scanning units.
