Insect-inspired smartphone projector focuses images onto uneven surfaces
If you were using a smartphone projector to shine an image onto an uneven surface, or onto a flat surface but at a diagonal angle, parts of the image would end up out of focus … unless, that is, your phone featured a new prototype LED projector developed by Germany’s Fraunhofer Institute for Applied Optics and Precision Engineering. Inspired by the compound eyes of insects, the device can reportedly display crisp, bright, distortion-free visuals onto irregular surfaces, and at non-perpendicular angles. Additionally, users can manipulate that display by reaching in and touching the projection surface
