Method and device for projecting an image with improved safety

Disclosed is a projection device including a MEMS mirror which oscillates about one or more oscillation axes to scan light from one or more lasers, across a display screen, to project pixels which define an image onto a display screen. Also disclosed is a display method including selecting a laser c...

description Disclosed is a projection device including a MEMS mirror which oscillates about one or more oscillation axes to scan light from one or more lasers, across a display screen, to project pixels which define an image onto a display screen. Also disclosed is a display method including selecting a laser class for the projection device; calculating a relationship between maximum accessible emission limit and distance, for the selected laser class; and selecting a desired maximum accessible emission limit for an image which is to be projected by the projection device onto said display screen.
