1. A system, comprising:
a polarization birefringence grating (PBG) interposed between an electromagnetic (EM) source and a first volume hologram;
the first volume hologram interposed between the PBG and a second volume hologram;
the second volume hologram interposed between the first volume hologram and a continuous steering element;
wherein the continuous steering element comprises:
a high-side electrode layer comprising:
a first plurality of electrical members alternated with, and electrically coupled to adjacent ones of a second plurality of electrical members;
wherein one of the first plurality of electrical members or the second plurality of electrical members comprises a plurality of discrete electrodes; and
wherein the other one of the first plurality of electrical members or the second plurality of electrical members comprises a plurality of resistors;
a low-side electrode layer; and
an electro-optic (EO) layer comprising an EO active material at least partially interposed between the high-side electrode layer and the low-side electrode layer, thereby forming a plurality of active cells of the EO layer;
wherein the PBG is responsive to a polarization of an incident beam from the EM source to selectively steer the incident beam to one of a first selected angle or a second selected angle;
wherein the first volume hologram is responsive to the first selected angle of the incident beam to increase a steered angle of the incident beam in a direction of the first selected angle; and
wherein the second volume hologram is responsive to the second selected angle of the incident beam to increase the steered angle in a direction of the second selected angle.
