ABSTRACT:
A projection apparatus is provided which produces a heads-up display in a helmet of the type commonly worn by a pilot. The projection apparatus includes a thin-film electroluminescent source having an edge emitter device provided therein. The edge emitter produces a linear signal which is transversely deflected by a scanner to produce an image on a display area. Preferably, the display area is provided on the face plate of a helmet worn by the pilot.
