Abstract: A panoramic imager comprising a mirror and a multi-scale imaging system is presented. The multi-scale imaging system comprises an objective lens and a plurality of cameras that is arranged in a non-planar arrangement at the image field of the objective lens. The objective lens reduces a first aberration introduced by the mirror, and each camera further reduces any residual first aberration. As a result, panoramic imagers of the present invention can provide improved image quality and higher resolution than panoramic imagers of the prior art.

Abstract: A means of enabling an imaging lens system that overcomes some of the costs and disadvantages of the prior art is disclosed. A lens system in accordance with the present invention reduces or eliminates one or more aberrations of an optical input by separating image collection functionality from image processing functionality. As a result, each function can be performed without compromising the other function. An embodiment of the present invention comprises a collection optic that provides a first optical field, based on light from a scene, to a processing optic that comprises a plurality of lenslets. The processing optic tiles the first optical field into a plurality of second optical fields.

Abstract: The present invention enables snap-shot spectral imaging of a scene at high image generation rates. Light from the scene is processed through an optical system that comprises a coded-aperture. The optical system projects a plurality of images, each characterized by only one of a plurality of spectral components, onto a photodetector array. The plurality of images is interspersed on the photodetector array, but no photodetector receives light characterized by more than one of the plurality of spectral components. As a result, computation of the spatio-spectral datacube that describes the scene is simplified. The present invention, therefore, enables rapid spectral imaging of the scene.
