Abstract
A projection device may include at least one first laser device and one second laser device, which is arranged opposite the first laser device. A prism is arranged between the two laser devices, wherein a polarization-dependent mirror device is arranged in the prism in such a manner that the beam of the first laser device is reflected in a direction that extends opposite the direction in which the beam of the second laser device is reflected. The polarization of the beam of the second laser device is then rotated, and the beam is deflected back to the polarization-dependent mirror device. The beam of the second laser device now passes through the mirror device without reflection due to the change in the polarization of the beam of the second laser device, such that two superposed laser beams of different polarization are available at the output of the projection device.
