Abstract
A projection device for generating dynamic projections includes: an arrangement of multiple light sources spaced apart from each other; a collimation optic for generating a parallel beam path from the light sources and a microlens array arrangement within the beam path of the collimation lens. The focal length of the lenses at the illumination side of the microlens array arrangement is larger than the distance of the lenses from a slide plane.
