Optical design of transmitter lens for asymmetric distributed free space optical networks

摘要

Highlights?Design method of aspheric lens for unconventional light shaping is presented.?Aspherical lens has the task to tailor asymmetric optical antenna emission.?Optical power is shaped according to distribution and orientation of receivers.?Proposed algorithm is based on 2D ray mapping, however extended to 3D.?Mathematical implementation is robust and convergent.AbstractWe present a method of transmitter lens design dedicated for light distribution shaping on a curved and asymmetric target. In this context, target is understood as a surface determined by hypothetical optical detectors locations. In the proposed method, ribbon-like surfaces of arbitrary shape are considered. The designed lens has the task to transform collimated and generally non-uniform input beam into desired irradiance distribution on such i
