    Author: Stamenov I, Arianpour A, Olivas SJ, Agurok IP, Johnson AR, Stack RA, Morrison RL, Ford JE.
    Journal: Opt Express; 2014 Dec 29; 22(26):31708-21. PubMed ID: 25607140.
    Abstract:
    Monocentric lenses provide high-resolution wide field of view imaging onto a hemispherical image surface, which can be coupled to conventional focal planes using fiber-bundle image transfer. We show the design and characterization of a 2-glass concentric F/1.0 lens, and describe integration of 5 Mpixel 1.75µm pitch back-side illuminated color CMOS sensors with 2.5µm pitch fiber bundles, then show the fiber-coupled lens compares favorably in both resolution and light collection to a 10x larger conventional F/4 wide angle photographic lens. We describe assembly of the monocentric lens and 6 adjacent sensors with focus optomechanics into an extremely compact 30Mpixel panoramic imager with a 126° "letterbox" format field of view.
