Abstract
A device for projecting an image. The device has a laser device, which is developed to emit a laser beam, the laser device having a modulation unit, which is developed to modulate image data onto the laser beam; and a micromirror device, which is developed to deflect the laser beam in a linear manner. The modulation unit is developed to modulate the laser beam in such a way that a predefined optical warning signal is emitted in a region around reversal points of the linear deflection.
