Abstract
An optical radar device has a vertical deflecting device which deflects an optical beam so as to emit the optical beam horizontally in a first half of reciprocal scanning in a horizontal direction and a part thereof upwards by a predetermined angle in a second half thereof. Thus, the optical radar device can detect both objects each with a reflecting portion installed at a low position such as a car and at a high position such as a truck.
