Abstract
A fusion night vision system has a plurality of hinged joints that allow an operator to adjust the distance between the left eye piece and the right eyepiece while allowing a row of pixels from a display to be maintained viewable through the right eye piece parallel with an imaginary line formed by an optical axis of the left eye piece with an optical axis of the right eye piece.
Claims20
A vision system, comprising:
- a first housing having a first optical axis, a display, an image combiner;
- and a first eye piece;
- and
- a second housing having a second optical axis and a second eye piece, the first housing coupled to the second housing through a first coupler, the first coupler having a first hinged joint rotatable about a first axis and a second hinged joint rotatable about a second axis, the first axis spaced a first fixed distance from the second axis, the second housing coupled to the first housing through a second coupler, the second coupler having a third hinged joint rotatable about a third axis, the first housing and the second housing coupled through the first coupler and the second coupler such that a row of pixels in the display when viewed through the first eye piece can be maintained parallel with an imaginary line going through the first optical axis and the second optical axis as the distance between the first optical axis of the first housing and the second optical axis of the second housing is varied.
