ABSTRACT:
An endoscope has an optical fiber and at least one photo-detector. The optical fiber has a core that transmits illuminating light and at least one cladding that surrounds the core and transmits reflected light. The cladding has a refraction slope surface that is tapered toward a direction opposite the tip portion of the optical fiber. The photo-detector detects the reflected light that exits from the refraction slope surface by refraction.
