Abstract

A laser projection device is described for projecting laser beams onto a projection plane, including a controllable multibeam laser diode unit; including a controllable optical deflection unit, which is designed in such a way that laser beams generated by the multibeam laser diode unit are deflected with the aid of the deflection unit; and including a control unit, which is designed in such a way that it controls the deflection unit to move laser beams deflected by the deflection unit onto a projection plane along a scanning line in such a way that different deflected laser beams run in the projection plane on the same scanning line.
