Abstract: A method and a device for projecting an image made up of pixels onto a projection surface, including a variable-intensity light source emitting a light beam and a decoupling device, and a deflection device directing the light beam onto a projection surface. In The light beam(s) are deflected such that the beams strike mirror facets of the polygonal mirror twice in a row. The diameter at which the beam strikes the first mirror facet of the polygonal mirror is adjusted such that it is dimensioned to practically not be cut by the facet edges. At the second strike, the light beam always intersects the mirror facet at the same location.
