Abstract

Imaging fibre bundles and a conical mirror have been used to construct a passive, endoscopic OCT probe with no scanning components at the probe tip. Circular scanning of the beam projected onto the proximal face of the imaging bundle results in a corresponding circular scan at the distal end of the probe. A 45° base-angle conical mirror turns the output light to produce a radially-directed beam that permits circumferential OCT scanning in quasi-cylindrical ducts.
