A laser sensor 2, which is mounted on a mobile body and detects the presence or absence of an incoming body in monitoring areas based on reflected light with respect to measurement light scanned to the monitoring area, includes a signal input unit to receive a signal from speed sensors mounted on the mobile body, a transfer information calculation unit to calculate a speed and acceleration of the mobile body from the signal inputted to the signal input unit, a monitoring area setting unit to variably set the monitoring area based on the speed and the acceleration calculated by the transfer information calculation unit, and a signal output unit to output an incoming body detection signal when the incoming body is detected in the monitoring area. |
