Abstract
A scanning angle expander that includes a converting optics for receiving an input beam, the input beam being inclined with respect with an optical axis of the converting optics by an input scan angle, and for converting the input beam to multiple output beamlets, each output beamlet being inclined with respect to the optical axis of the converting optics by an output scan angle; and expanding optics, for converting the multiple output beamlets to an output beam that is substantially parallel to the output beamlets, whereas the output beam and the input beam have substantially a same size.
