Abstract
An object detection device includes: a scanning optical system configured to scan a space by measurement light and guide reflected light from an object; a distance calculation circuit configured to calculate a distance and a direction to the object based on physical relationship between the measurement light and the reflected light; an object determination circuit configured to determine whether the distance and the direction to the object are within a predetermined monitoring region; a signal output circuit configured to output an object detection signal upon determination that the object is within the monitoring region; and a mode switching circuit configured to switch to either a first mode in which it is determined whether the object is within the monitoring region regardless of an intensity of the reflected light and a second mode in which such determination is performed only when the intensity is at or above a predetermined threshold.
