Abstract
An example system includes a first steering lens positioned between an EM source and a second steering lens, and the second steering lens positioned between the first steering lens and an emission lens. The example system includes the first and second steering lenses having a combined first effective focal length, and where the emission lens is a positive lens have a second focal length. The example system includes the first effective focal length being shorter than the second focal length. The example system includes a first steering actuator that move the first steering lens along a first movement course, and a second steering actuator that moves the second steering lens along a second movement course.

A system, comprising:
- an initiating optics layer interposed between an electromagnetic (EM) source and a lenslet steering layer;
- the lenslet steering layer comprising a first positive lens element and a second negative lens element, the lenslet steering layer interposed between the initiating optics layer and a concluding optics layer;
- 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;
- and
- a rotating actuator responsive to rotation commands from the steering controller, wherein each of the first positive lens element and the second negative lens element is independently rotatable around an optical axis.
A system, comprising:
- an initiating optics layer interposed between an electromagnetic (EM) source and a lenslet steering layer;
- the lenslet steering layer comprising a first positive lens element and a second negative lens element, the lenslet steering layer interposed between the initiating optics layer and a concluding optics layer,
- wherein at least one of the first positive lens element or the second negative lens element comprises an offset portion of a reference lens;
- a steering controller configured to steer an EM beam from the EM source by controlling rotation of the first positive lens element and the second negative lens element;
- and
- a rotating actuator responsive to rotation commands from the steering controller.
