Beschreibung
Zusammenfassung:	A laser radar device includes: a projector projecting measuring light to a forward direction of a vehicle multiple times during a predetermined detection period; light receiving elements receiving reflected light of the measuring light from detection areas having different directions in a horizontal direction; a measurement section selecting at least one of light reception signals from the light receiving elements and measuring a light reception value by sampling the selected light reception signal; an integrator integrating the light reception values of the light reception signals from the identical light receiving element at an identical sampling clock time; a detector detecting an obstacle in each detection period based on the integrated light reception value; and a sensitivity controller increasing the number of times of integrating the light reception values of at least a part of the light receiving elements, under predetermined conditions.
