Micro-lens panoramic imager

An imaging system for processing incident optical radiation emitted from a source comprising:

• a first lenslet array of micro-lenses each having a first focal length (f.sub.1), a first pitch, and a first lens diameter (d.sub.1), positioned about a portion of a first spherical surface having a first radius of curvature (r.sub.1) at a first longitudinal distance along an axis to intercept said incident optical radiation;
• and
• a second lenslet array of micro-lenses each having a second focal length (f.sub.2), second pitch, and a second lens diameter (d.sub.2) positioned about a portion of a second spherical surface having a second radius of curvature (r.sub.2) adjustably positioned at a second longitudinal distance along said axis to intercept radiation emerging from said first lenslet array,
• said second lenslet array configured to be concentric with said first lenslet array and being separated along said optic axis from said first lenslet array by a predetermined amount such that said incident radiation is focused by the combined action of a plurality of pairs of corresponding lenslets from said first and second lenslet arrays to an erect overlap image in a substantially spherical focal surface transverse to said optic axis located at distance C from said second spherical surface.
