Abstract

An optical fiber sensor is composed of an outer portion generally in the form of a tube which constitutes an illumination light transmission path. Inside the tube is formed or inserted an image path for directing image light back to an observation point. A longitudinal hole may be formed beside or surrounding the image path for conducting a fluid to the observed location. The sensor is especially suitable for medical image catheter or endoscopic usage.
