This invention discloses a highly scalable and modular automated optical cross connect switch comprised of large numbers of densely packed fiber strands suspended within a common volume. In particular, apparatus and methods enabling programmable interconnection of large numbers of optical fibers (100's-1000's) having structured and coherent braid representations are provided.

Braided fiber optic cross-connect switches

Modified MZ (Mach-Zender) interferometers are utilized to analyze the transmitted, aspherical wavefront of an ophthalmic lens by mounting the lens in a cuvette having a rotatable carousel that can hold multiple lenses. Fresh, temperature controlled, saline solution is circulated about the lenses, and the cuvette is positioned in a vertical test arm of the interferometer configuration. Reverse raytracing is utilized to remove aberrations induced into the wavefront as it is imaged from immediately behind the lens to the detector of the interferometer.
