Abstract

Fashionable Augmented Reality Smartglasses require ultra-compact high performance display solutions of high brightness and extremely low power consumption. Laser Beam Scanning (LBS) offers some advantages over other microdisplay technologies particularly with respect to brightness, contrast, size, weight and power consumption. A biaxial piezoelectric MEMS scanning mirror that is operated in resonance in a miniature vacuum environment consequently minimizes power consumption and also allows reducing projector size to a minimum. MEMS mirror based laser scanning is not only the key to stylish AR smartglasses it also enables building extremely compact depth sensing cameras that are the basis for enabling interactivity – not only in the Metaverse
