Projection device for use with a night vision goggle system
Abstract:
A projection device for use with a night vision goggle system includes: a display source; a projector lens assembly positioned to accept light from the display source and provide a projector optical path having a plurality of projector rays; and a folding device comprising at least two folding surfaces positioned to split an exit pupil of the projector optical path into two or more separated segments. Each folding surface captures and redirects a portion of the projector rays to be parallel and coincident with corresponding rays produced by an external scene which pass through an objective lens of the night vision goggle system.
