1. 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 (f1), a first pitch, and a first lens diameter (d1), positioned about a portion of a first spherical surface having a first radius of curvature (r1) 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 (f2), second pitch, and a second lens diameter (d2) positioned about a portion of a second spherical surface having a second radius of curvature (r2) 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.
