Abstract
We present a three-dimensional (3D) endoscopic optical coherence tomography (OCT) system based on a dual-axis scanning microelectromechanical system (MEMS) mirror. The diameter of the MEMS mirror was 1.2mm and both axes were capable of scanning greater than 20° with linearity. The endoscopic MEMS probe was integrated with an OCT system and volume images were obtained at a rate of 3frames∕s by means of two-axis lateral scanning combined with an axial scan. In the initial investigations, 3D OCT images of healthy rabbit trachea as well as images of normal and cancerous regions of hamster cheek pouch tissue were obtained.

Optical coherence tomographyOCTis an emerging technology that is capable of high resolution, minimally invasive, nondestructive, and real time imaging
OCT is based on optical coherence reflectometry which is analogous to ultrasound imaging but utilizes a broadband light source instead of sound waves to measure the intensity of back reflection as function of depth in the sample
