The array projector developed by Peter Dannberg, Peter Schreiber (from the left) and Marcel Sieler (not shown) projects an extremely bright image in spite of its minimal size.

An image projected on a slanted or curved surface appears distorted and can appear out of focus in some areas. A high-intensity mini-projector about the size of a Euro cent coin from the Fraunhofer IOF in Jena, Germany can now correct for this effect. The projector‘s secret: Hundreds on tiny lenses inspired by the model of an insect‘s compound eye.
