Abstract
A system and method for an endoscopic optical coherence tomography (OCT) system based on a CMOS-MEMS mirror to facilitate lateral light scanning. The laser scanning scope, adapted to the instrument channel of a commercially-available endoscopic sheath, allows for the real-time cross-sectional imaging of living biological tissue via direct endoscopic visual guidance. A conventional rod lens imaging system may be used for the visual guidance. The MEMS mirror is preferably actuated using either or both of a thermal-mechanical or electrostatic actuation system. More than one MEMS micromirror may be used in a single system for 3D imaging.
