Combining Generalized Phase Contrast with matched filtering into a versatile beam shaping approach

Abstract

We adapt concepts from matched filtering to propose a method for generating reconfigurable multiple beams. Combined with the Generalized Phase Contrast (GPC) technique, the proposed method coined mGPC can yield dynamically reconfigurable optical beam arrays with high light efficiency for optical manipulation, high-speed sorting and other parallel spatial light applications [1]. © 2010 IOP Publishing Ltd.
