Compact and High-Brightness Helmet-Mounted Head-Up Display System by Retinal Laser Projection

A compact binocular heads-up display integrated in a motorcycle helmet is presented and characterized. The use of a laser micro-projector using a 2D MEMS-mirror enables the formation of a bright image, superimposed on the user vision. A fully-functional and adjustable 3D-printed prototype, thereby fitting the morphology of most users, is presented.
