Abstract:
An object detection device includes a first optical transceiver that generates a first beam flux and receives a scattered portion of the first beam flux, a second optical transceiver that generates a second beam flux and receives a scattered portion of the second beam flux, and a mirror unit that rotates around a rotation axis. The first beam flux is reflected by the mirror unit and is scanned based on the rotation of the mirror unit, and the scattered portion of the first beam flux is generated by scattering of the first beam flux by an object. The scattered portion of the first beam flux is reflected by the mirror unit before being received by a light receiving portion of the first optical transceiver, and the second beam flux is reflected by the mirror unit and is scanned based on the rotation of the mirror unit.
