Researchers from the University of Fukui, in collaboration with SEIREN KST Corp., a Japanese silicon manufacturer, are preparing to commercialize an image projector for eyewear displays.
The team succeeded in creating an optical engine by integrating a compact RGB module measuring 8 × 4 × 3 mm with a microelectromechanical system (MEMS) mirror. The direction in which the MEMS mirror reflects light from the laser module can be controlled electronically, making it possible to project high-quality 3D images through laser scanning over the projected area.
