A user portable viewing device includes a plurality of non-coaxially aligned sensors for sensing a scene. A processing element combines electronic images into a single electronic image. A display displaying the combined electronic image is adaptable for mounting in an optical axis including an eye of the user and an input end of the first sensor for direct view. In a second embodiment, a system for fusing images comprises sensors for generating sets of image data. An information processor receives and samples the sets of image data to generate sample data for computing a fused image array. A display receives the fused image array and displays a fused colorized image generated from the fused image array.

Digitally enhanced night vision device

A method and system for fusing image data includes an electronic circuit (L) for synchronizing image frames. An adaptive lookup table unit () receives the image frame data sets and applies correction factors to individual pixels. The size of an image is then scaled or otherwise manipulated as desired by data formatting processors (and). Multiple images communicated within parallel circuit branches (Pand P) are aligned and registered together with sub-pixel resolution.

System for multi-sensor image fusion

An image intensification camera system (C) for gathering image data includes an image intensifier () for amplifying received light (). A relay optic assembly () is coupled between the image intensifier () and a digital image sensor (), such as a CMOS or CCD device. Digital logic () is used to process or output an image or related data ().

A sensor unit (F) has at least a first and second sensor () arranged along a sensor axis (). A head adapter () provides support to mount at least one selected device about a user's cranium (). A securing module () is attached to the sensor unit for mounting the sensor unit (F) to the head adapter (). The sensor unit (F) is to be mounted above an ocular axis () formed between a pair of eyes () of the user (U) when the sensor unit (F) is attached to the head adapter element (). When the sensor unit (F) is secured to the user (U) with the head adapter element (), the sensor axis () is essentially perpendicular to the user's ocular axis ().

Centerline mounted sensor fusion device

An InGaAs Image Intensifier ('I2') Camera (C) detects and forms an image () to be viewed. An InGaAs photocathode Image Intensifier () is used to pass an amplified signal () from a screen (). The InGaAs image intensification tube () is optically coupled () to an imaging device () for passing output light. The output light () from the InGaAs tube () is transformed by an electronic circuit () producing a desired signal output (). The signal output () from the electronic circuit () may be further enhanced into an enhanced signal output (). The enhanced signal output may be formatted into a form for viewing or may be saved.

An event synchronizing apparatus E for an image intensification camera system C for gathering image data includes an image intensifierfor amplifying received light. A relay optic assemblyis coupled between the image intensifierand a digital image sensor, such as a CMOS or CCD device. Digital logicis used to process or output an image or related data. An event detectordigitizes an input signalfrom an illumination sourceand generates an electrical output synchronization signalin response to the input optical signal. The image intensifier camera C derives imaging and control information for the synchronization signal.

Event synchronization for detector systems

A system (S) for combining multi-spectral images of a scene includes a channel ( ) for transmitting a scene image ( ) in a first spectral band. A separate, second detector ( ) senses the scene in a second spectral band. The second detector ( ) has an image output that is representative of the scene. A display ( ) displays an image ( ) in the second spectral band. A beam mixer ( ) combines the image output ( ) in the first spectral band with the displayed image ( ), and conveys the combined multi-spectral images to an output ( ) for a user (U).

Enhanced night vision goggle assembly

A system (S) for mounting and aligning a detector (D) about an observation instrument ( ) includes a first detector ( ) movably coupled to the observation instrument ( ) off an axis of observation centerline ( ) for the observation instrument ( ). A retainer ( ) is mounted with the observation instrument ( ) to secure the first detector ( ) to the observation instrument ( ). The retainer ( ) permits rotatable movement of the first detector ( ) about the axis of observation centerline ( ). The retainer ( ) also preferably includes an attachment point ( ) for mounting the first detector ( ) to the retainer ( ). The first detector ( ) should be adjustable at least about an axis ( ) essentially perpendicular to the axis of the observation centerline ( ) for the observation instrument ( ).
