Image-intensifying devices (for example, glasses, goggles, etc.) suitable for certain commercial and entertainment applications by virtue of their light weight, small size, and economical production are disclosed. In one embodiment, input light passes through an Amici reflector, which is used to adjust the orientation of the intensified image to register it with the real world. In another embodiment, input light passes through at least two Amici reflectors, which are used to adjust the orientation of the intensified image to register it with the real world. In alternate embodiments, at least one Amici reflector folds the light at a non-perpendicular angle and/or input light is rotated by an angle other than (180&#xb0;). Other embodiments include a field-flattening lens disposed in front of an image intensifier. The intensified image is then sent through a projective lens assembly to reach the viewer's eye.

Night vision devices and methods

A head up display or HUD system, including methods and apparatus, suitable for use in a flight simulator. According to the present teachings, a flight simulator HUD may be configured to produce a HUD image that appears superimposed on a simulated cockpit field of view image, and which has substantially the same relatively short focal distance from the user as the simulated image. A simulator HUD according to the present teachings does not require any holographic optical elements or an unrealistic cockpit volume, and provides an accurate simulation of conditions in a real aircraft cockpit.

Optical design of a wide field of view pupil forming HUD

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.

Visor heads-up display

Image-intensifying or night vision glasses 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 embodiment, input light passes through two Amici prisms and a field-flattening lens to reach an image intensifier. The intensified image it produces is reflected off a first folding mirror, passes through a lens, reflects off a curved mirror, and passes back through the lens the other way. The intensified image then passes through two additional, non-doublet lenses, between which an intermediate image exists. The intensified image then reflects off the 'lens' or visor of the glasses and proceeds to the pupil of the eye of the wearer. Alternative embodiments use a helmet visor, mirror, or other (at least partially) reflective surface for the final reflection.
