12 March 2014 Amplitude, phase, and polarization control with a single spatial light modulator
Author Affiliations +
Point spread function engineering is usually accomplished by controlling the amplitude, phase and/or polarization of the pupil fields. We analyze and test an optical design for full amplitude, phase, and polarization control of the pupil fields using a single spatial light modulator. In our scheme, the beam is spatially split into four components whose relative phases provide the four degrees of freedom necessary for amplitude, phase, and polarization control.
