3rd order aberration analysis of gradient index arrays

Thesis (M.S.)--University of Rochester. College of Engineering and Applied Science. Institute of Optics, 1984. This thesis was digitized by the Institute of Optics in 2014 and was determined to have lapsed into the public domain.

Algorithms have been developed to account for plus unit magnification arrays and arrays with reduced magnification. A unit magnification array with short conjugate distances is designed and analyzed. A video camera lens system consisting of a homogeneous subsystem and unit magnification array is analyzed. A reduction array comprised of tilted gradient index rods with tilted surfaces is analyzed. The results via third order approximation are compared to real raytracing results. It has been found that third order aberration theory yields accurate results and is considerably cheaper than real raytracing
