Abstract: A wearable system is shown that presents one or more heads-up displays to the wearer. A data source provides information to an image generator that is sufficient to generate one or more display images, which are still or moving, characters or graphical displays. The output image from the image generator passes through a lens, reflects off a curved mirror, and passes back through the lens the other way. The image then passes through two lenses, between which an intermediate image exists. The image reflects off the “lens,” or visor, of the glasses and proceeds to the pupil of the wearer's eye. Alternative embodiments use a helmet visor, mirror, or other (at least partially) reflective surface for the final reflection.

Abstract: Image-intensifying glasses 100 are disclosed that are suitable for certain commercial and entertainment applications by virtue of their light weight, small size, and economical production, compared to certain other night vision products. In one disclosed embodiment, input light passes through two Amici prisms 144 and 148 and a field-flattening lens 150 to reach an image intensifier 152. The intensified image it produces is reflected off a first folding mirror 162, passes through a lens 154, reflects off a curved mirror 156, and passes back through the lens 154 the other way. The intensified image then passes through two additional, non-doublet lenses 158 and 160, between which an intermediate image exists. The intensified image then reflects off the “lens,” or visor 130, of the glasses and proceeds to the pupil of eye 131 of the wearer. Alternative embodiments use a helmet visor, mirror, or other (at least partially) reflective surface for the final reflection.
