Abstract: An electro-optical beamsteerer can be coupled with other optical structures. For example, such optical structures can be used to shape a beam being steered by the beamsteerer or shape a field-of-regard (FOR) addressable from the perspective of the beamsteerer. Optical elements placed at an output of the LCW can be used as a “spot mapper” to increase or decrease the field of view that can be scanned by a beam steered by the LCW, as an illustrative example, Lenses or other optical elements can also be used to correct distortion in the steered beam distribution across the field of view, such as to provide a “smile corrector.” In a similar manner, optical elements can be placed at an input to the beamsteerer, such as to provide a beam expander to change the size of the beam profile inside the beamsteerer device.
