Abstract

A mosaic imaging system comprises a support structure, a plurality of individual focal plane arrays secured to the support structure and an afocal primary objective optical element secured to the support structure. Each focal plane array has its own objective optical element secured in relation thereto so that the focal plane array and the objective optical element have a constant spatial relationship, with each objective optical element focusing its respective focal plane array to infinity. The primary objective optical element has an exit pupil subsuming the entrance pupils of the objective optical elements of the focal plane arrays, and is arranged relative to the objective optical elements of the focal plane arrays to maintain throughput and image integrity from object space of the primary objective optical element to each focal plane array. Two or more of the plurality of the individual focal plane arrays may occupy different geometric planes.

Claims

1. A mosaic imaging system, comprising:

a support structure;

a plurality of individual focal plane arrays secured to the support structure;

each focal plane array having its own objective optical element secured in relation thereto so that the focal plane array and the objective optical element have a constant spatial relationship to one another, with the objective optical element focusing the focal plane array to infinity;

an afocal primary objective optical element secured to the support structure;

the primary objective optical element having an exit pupil subsuming entrance pupils of each of the objective optical elements of the focal plane arrays;

the primary objective optical element arranged relative to the objective optical elements of the focal plane arrays to maintain throughput and image integrity from object space of the primary objective optical element to each focal plane array.

2. The mosaic imaging device of claim 1, wherein at least two of the individual focal plane arrays occupy different geometric planes.

3. The mosaic imaging system of claim 1, wherein each focal plane array having its own objective optical element secured in relation thereto comprises an individual camera comprising that focal plane array and in which the objective optical element is an integrated objective optic lens of that camera.

4. The mosaic imaging system of claim 1, wherein the integrated objective optic lens of each individual camera is less than 2 millimeters in diameter.
