A dichroic type narrow-band-pass filter is used as a beamsplitter inside a night vision goggle eyepiece. The filter is combined with appropriately aligned polarizers and liquid crystal type shutter rotators movable between a 'P' orientation and an 'S' orientation to transmit center band and side band wavelengths of the normal view or night scene for recording, transmitting or enhancing. In the enhanced low light level mode, the intensified visible image presented to the user comprises a 40 degree circular image with a 30 degree by 22.5 degree rectangular display insert.

Image enhancement system and method for night goggles

A modular binocular-like vision assembly () has individual interconnecting inner () and outer () optical modules. Each module is separately sealed and self-contained and includes image intensifier means for converting incoming light to an intensified visible image for presentation to the eyes of the observer in low light conditions. Electrical connectors are provided between the modules for permitting free flow of electrical power and information between the modules. Attaching system is provided for removably attaching the outer modules to the inner modules to deliver a panoramic field of vision and removal of any single module from the assembly will not break any pressure seals or degrade the optical performance of the removed module or the remaining modules.

Modular panoramic night vision goggles

An optical path switch and a method of using thereof, for creating two optical pathways for input light. The switch is composed of two polarizers that polarize the input light and two polarization rotators each having two positions. The polarization rotators position translates to one of two the optical pathways. Additionally, the optical path switch has an image enhancement device for producing an enhanced image of the light, and a beam splitter that directs the light to two channels. The optical path switch works by polarizing the light by one of the two polarizers producing an output, following, the output is then directed through the beam splitter where the output is directed towards the two channels. Next, the output is then filtered through the two polarization rotators and to the other of the two channels where the positions of the two polarization rotators switch the optical pathways.
