Color reflectance fiber bundle endomicroscopy without back-reflections

Abstract. Coherent fiber imaging bundles can be used as passive probes for reflectance-mode endomicroscopy providing that the back-reflections from the fiber ends are efficiently rejected. We describe an approach specific to widefield endomicroscopy in which light is injected into a leached fiber bundle near the distal end, thereby avoiding reflections from the proximal face. We use this method to demonstrate the color widefield reflectance endomicroscopy of ex vivo animal tissue.
