Abstract
Optical scanning with an optical probe composed of an elongated cylinder of transparent material mounted upon an optical scanner body; one or more sources of scan illumination mounted in the probe distally or proximally with respect to the scanner body and projecting scan illumination longitudinally through the probe; a radially-reflecting optical element mounted in the probe having a conical mirror on a surface of the radially-reflecting optical element, the mirror oriented so as to project scan illumination radially away from a longitudinal axis of the probe with at least some of the scan illumination projected onto a scanned object; a lens mounted in the probe between the radially-reflecting optical element and the scanner body and disposed so as to conduct to an optical sensor scan illumination reflected from the scanned object.
