The German-based Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology (FEP) has developed a coating, which is required to expand the diameter of a laser beam by more than a factor of one hundred. With this coating, backlighting for holographic displays can be realised in the future. The main aim of the project is to provide an approach for 3D television sets that work without annoying 3D glasses. Holographic displays would be a giant step in this direction. Moreover, medical scientists could inspect spatial images of the inside of the body and observe detailed movements of organs.
