Abstract
A wide FOV binocular imaging system utilizes an imaging structure (14) to produce an intermediate image (16), and a field lens (18) and beam splitting surface (20) located proximate the intermediate image to concentrate, split, and direct the light from the intermediate image into an eye lens (22) at two viewing zones exit pupils (22(a), 22(b)). The present invention produces a wide FOV and comfortable exit pupil while employing a single entrance pupil.
Claims17
A binocular imaging system comprising:
- means for forming an intermediate image of an object;
- a field lens positioned proximate the intermediate image for concentrating the intermediate image;
- a beam splitting means positioned proximate the intermediate image for imparting a positive angular deviation to a portion of the intermediate image and a negative angular deviation to the remaining portion of the intermediate image;
- and
- means for re-imaging the positive angular deviation and negative angular deviation in the intermediate image to form respective left and right eye virtual images.
