Optical coherent tomographic (OCT) imaging apparatus and method using a fiber bundle
First Claim
1. An improvement in an OCT system for imaging a sample having a sample arm with a scanner, the improvement comprising a fiber optic bundle having a proximal entrance aperture which is optically coupled to the sample arm through the scanner and having a distal exit aperture optically directed to the sample remote from the scanner.

Abstract
A fiber-optic bundle based optical coherence tomography (OCT) probe method is demonstrated in a multimode optical fiber bundle based OCT system. The system can achieve a lateral resolution of 12 μm and an axial resolution of 10 μm using a super-luminescent diode source. This imaging approach eliminates any moving parts in the probe and has a primary advantage for use in extremely compact and safe OCT endoscopes to image internal organs and great potential to be combined with confocal endoscopic microscopy.
