Augmented reality system using display with fiber-optic faceplate

A binocular head-mounted augmented reality system (1) comprising:

• two identical display units (8), each with a pixelated display (3) with a width of the emitting area in the range of 30 to 45 mm and a height in the range of 25 to less than 40 mm, and a pixel pitch in the range of 15-50 μm, where each display (3) has a planar emissive surface in direct optical contact with a fiber optic faceplate (5) so that an image emitted by the display (3) passes through the faceplate (5) and is emitted at a curved surface (5B) on the opposite end of the faceplate;
• and
• a curved semi-transparent visor (9) having two reflective sections (9A1, 9A2) arranged to reflect the emitted image from each display unit (8) towards the eyes (12) so that the reflected images are combined into a single viewed image along with external light passing through the visor (9);
• and
• wherein the reflective sections (9A1, 9A2) each have a freeform surface whose surface elevations from a base plane change symmetrically on either side of a center line (AofS) that runs through a center point (CP) in a first direction but changes asymmetrically on either side of a center line (AofA) through the same center point in a second direction which is orthogonal to the first direction.
