Abstract
An optical system and method comprising acquiring radiation in a plurality of spectral bands, each acquired by a discrete collector, receiving the acquired radiation in one or more of the spectral bands with one or more afocal zoom optics, each receiving radiation from a different collector, and aligning each point of fields of view of the collectors to a fraction of a pixel.
Claims20
An optical system comprising:
- a plurality radiation collectors, each operating in a different spectral band;
- one or more afocal zoom optics, each receiving radiation from one of said collectors;
- and
- means for combining the radiation from said plurality of collectors after passing through said zoom optics;
- and
- wherein each point of fields of view of the collectors align to a fraction of a pixel.

An optical method comprising the steps of:
- acquiring radiation in a plurality of spectral bands, each acquired by a discrete collector;
- receiving the acquired radiation in one or more of the spectral bands with one or more afocal zoom optics, each receiving radiation from a different collector;
- combining the radiation from the plurality of collectors after passing through the zoom optics;
- and
- aligning each point of fields of view of the collectors to a fraction of a pixel.
