Abstract:
A method is described for generating a visible image on a projection surface, in the course of which visible light is emitted from a first laser resonator, the visible light is deflected in the direction of the projection surface with the aid of a deflection element, in particular a micromirror, in order to generate the image, and a light spot of visible light is generated on the deflection element, and invisible light is emitted from a second laser resonator, and a light ring is generated on the deflection element from the invisible light, which enlarges the light spot.
