US Patent:

42284201, Oct 14, 1980

Filed:

Sep 14, 1978

Appl. No.:

5/942228

Inventors:

Edward E. Fenimore - Los Alamos NM
Thomas M. Cannon - Los Alamos NM

Assignee:

Department of Energy - Washington DC

International Classification:

G02B 500
G03B 517

US Classification:

3401463F

Abstract:

The present invention pertains to a mosaic of coded aperture arrays which is capable of imaging off-axis sources with minimum detector size. Mosaics of the basic array pattern create a circular on periodic correlation of the object on a section of the picture plane. This section consists of elements of the central basic pattern as well as elements from neighboring patterns and is a cyclic version of the basic pattern. Since all object points contribute a complete cyclic version of the basic pattern, a section of the picture, which is the size of the basic aperture pattern, contains all the information necessary to image the object with no artifacts.

International Classification:

G01T 100

US Classification:

3401463F

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.
