NIGHT VISION DEVICES AND METHODS

摘要

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°). 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.

主权项

1. Night vision apparatus, comprising:
an optical subsystem with a first Amici reflector located along an optical path; and an image intensifier connected to the optical subsystem and located along the optical path; wherein the optical subsystem rotates an image entering the optical subsystem by an angle other than one hundred eighty degrees (180°) and other than a multiple of one hundred eighty degrees (180°).
