Abstract

Electro-optical (EO) sensors on future aerospace systems will require extensive beam delivery control. While both beam shaping and steering have been demonstrated in the past, simultaneous demonstration of these techniques (for a common aperture) has not. We demonstrate the use of phase-retrieval based algorithms which has been previously used for simultaneous beam shaping and steering in the far field. Experimental results using a segmented, phase-only, liquid crystal wavefront control device are presented.
