ABSTRACT:
Optical apparatus for scanning radiation over a surface includes a plurality of angularly spaced rotating arms extending from a central axis. A central reflector is positioned at the axis of the arms and a radially remote reflector is positioned on each arm for folding an optical radiation path toward the object to be scanned. The central reflector rotates with the arms but is sequentially indexed into optical path alignment with each radially remote reflector so that a beam of radiation in the optical path is scanned over the same predetermined arcuate segment by each of the remote reflectors.
