Abstract
A spreading optics system distributes electromagnetic (EM) waves emitted by an emitter having an emission vector. The spreading optics system includes reflective surfaces. The reflective surfaces include concave first reflector having a concave cross section in a plane substantially perpendicular the emission vector. The reflective surfaces further include a convex second reflector arranged further from the emitter than the concave first reflector. The convex second reflector has a convex cross section in a second plane substantially parallel the first plane. The reflective surfaces are configured to divergently redirect the EM waves into a vector fan at a predetermined angle relative to the emission vector.
