Japanese laser projector beams HD video to retina
Scientists in Japan have developed a miniaturised laser projector system that could display HD colour video via smart glasses or directly on to the retina.
Underpinning the technology is an optical engine that integrates an 8×4×3 mm RGB (Red, Green, Blue) laser module with a microelectromechanical (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 2D images through laser scanning over the projected area.
Developed at the University of Fukui in collaboration with Seiren KST, the work was recently presented at the 27th International Display Workshop and could be commercialised within a year, according to its creators.

"At the University of Fukui, we are trying to stir things up in the wearable display industry by developing smart glasses with optical engine, driver circuit, projector, and battery all integrated in one single device,” said the university’s Asst Prof Akira Nakao, lead author of the study.
