Title: METHOD AND DEVICE FOR PRODUCING A VISIBLE IMAGE ON A PROJECTION SURFACE
Abstract:
The invention relates to a method for producing a visible image on a projection surface, where visible light is emitted from a first laser resonator, and the visible light is deflected in the direction of the projection surface by means of a deflection element (6), particularly a micromirror, in order to produce the image, where a light spot (8) consisting of visible light is produced on the deflection element (6), where invisible light is emitted from a second laser responator, and where a light ring (9) is produced from the invisible light on the deflection element (6), said light ring enlarging the light spot.
