Abstract
Very compact, high numerical aperture, high resolution, ultra-wide field of view concentric optical apparatus. The concentric optical apparatus comprises a concentric lens and a focal surface array disposed along a focal surface of the concentric shell outer lens. The optical apparatus may further comprise an image intensifier tube optically coupled to the concentric lens by way of a curved fiber optic relay having an input surface that is concentrically disposed with respect to the concentric lens. The optical apparatus may also comprise a dewar that houses the focal surface array, and wherein the concentric lens comprises a cold stop for the focal surface array.

Ultra-wide field optical apparatus comprising:
- a concentric sensor comprising:
- a concentric lens that comprises a front shell lens, a central ball lens, and a rear shell lens and air gaps between adjacent surfaces of the front, central and rear lenses;
- and
- a focal surface array con centrically disposed around a portion of the concentric lens.
Ultra-wide field optical apparatus comprising:
- a concentric sensor comprising:
- a concentric lens comprising a front shell lens, a central ball lens, and a rear shell lens;
- and
- a focal surface array concentrically disposed around a portion of the concentric lens, and wherein the pixel density of a central region of the focal surface array is very high for tracking or identification, and an outer low density region of the focal surface array provides for acquisition or search.
Ultra-wide field optical apparatus comprising:
- a concentric sensor comprising:
- a concentric lens comprising a front shell lens, a central ball lens, and a rear shell lens, and wherein the concentric lens comprises a cold stop for the focal surface array;
- a focal surface array concentrically disposed around a portion of the concentric lens;
- and
- a dewar that houses the focal surface array.
Ultra-wide field optical apparatus comprising:
- a concentric sensor comprising:
- a concentric lens comprising a front shell lens, a central ball lens, and a rear shell lens;
