Paper Abstract

A novel retroreflector design using a pseudo-phase-conjugation mirror, viz., a corner cube mirror array (CMA), is proposed for light-collecting systems to increase the apparent brightness of the light source and thus increase the light collection efficiency. Measurement data for a dual paraboloid reflector system using a CMA retroreflector are presented. Design issues for the CMA are discussed. The advantages of the CMA retroreflector are: (1) it is a self-aligning technique, so it works regardless of its shape and position; (2) it is self-compensated for image distortion. Therefore a highly efficient low-cost light collection system with bigger manufacture tolerances is possible.
