Abstract

A 3-dimensional, endoscopic optical coherence tomography (OCT) system based on a high-speed micromachined scanning mirror is presented. Cross sectional images of in-vitro and in-vivo samples are obtained and continuously displayed to the user. The optical resolution of the system is approximately 20 mumtimes20 mumtimes10 mum. The endoscopic OCT probe has been utilized to identify cancerous regions of hamster cheek pouch tissue in real-time
