Abstract

The demand for 3D displays for virtual, augmented and mixed reality is increasing rapidly. While there are a number of such displays already available, there is still a need for improvement of the user experience. The best possible solution is the full reconstruction of a natural light field by real holography for perfectly realistic images. For this, a novel type of piston mode micro mirror spatial light modulator (SLM) is required, with pixels of only a few micrometers pitch precisely addressable to one of many deflection states. Fraunhofer IPMS and SeeReal together with consortium partners started developing such an advanced MEMS (micro electro mechanical system) SLM with unique properties.
