Abstract
Abstract A system utilizing uniformly redundant arrays to image non-focusable radiation. The uniformly redundant array is used in conjunction with a balanced correlation technique to provide a system with no artifacts such that virtually limitless signal-to-noise ratio is obtained with high transmission characteristics. Additionally, the array is mosaicked to reduce required detector size over conventional array detectors.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
52 words
A device for imaging a source of radiation comprising: a uniformly redundant array aligned to aperture image said source of radiation; means for detecting said radiation imaged by said uniformly redundant array; means for balance correlating information from said means for detecting to generate a decoded image of said source of radiation.
Claim 2
Independent Claim
52 words
A device for imaging a source of radiation comprising: a uniformly redundant array aligned to aperture image said source of radiation; means for detecting said radiation imaged by said uniformly redundant array; means for balance correlating information from said means for detecting to generate a decoded image of said source of radiation.
Claim 3
Independent Claim
46 words
A device for imaging a source of radiation comprising: a uniformly redundant array aperture aligned to project an encoded image of said source of radiation; means for detecting said encoded image; means for balance correlating said encoded image to generate a decoded image of said source.
Claim 4
Independent Claim
