1. A device for optically recording an underbody of a vehicle, the device comprising: at least one camera disposed to the side of a longitudinal axis of the vehicle so that a line of sight of the camera is perpendicular to the longitudinal axis of the vehicle; and a plurality of mirrors disposed and oriented in such a way that images of several areas of the underbody of the vehicle are able to be recorded simultaneously by the camera when the vehicle is positioned over the device, wherein: all of the mirrors are staggered with respect to each other in the longitudinal direction of the vehicle so that reflective surfaces of all the mirrors face the same direction and so that any axis running perpendicularly to the longitudinal axis of the vehicle intersects only one of the mirrors.
