Abstract
A system includes an initiating optics layer interposed between an electromagnetic (EM) source and a lenslet steering layer, where the lenslet steering layer includes a first positive lens element and a second negative lens element. The lenslet steering layer is interposed between the initiating optics layer and a concluding optics layer. The system includes a steering controller configured to steer an EM beam from the EM source by controlling a first relative rotation between the first positive lens element and the second negative lens element, and further by controlling a second absolute rotation of the lenslet steering layer. The system includes a rotating actuator responsive to rotation commands from the steering controller, where the rotating actuator selectively rotates the first positive lens element and/or the second negative lens element.
