Coded aperture imaging with uniformly redundant arrays
First Claim
Patent Images
1. 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.

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.
