ABSTRACT:
A surface inspection apparatus has a detection unit that irradiates an inner circumferential surface of an inspection object with inspection light from a laser diode through a light projecting fiber, and detects the intensity of the reflected light of that inspection light. The detection unit comprises a first light receiving fiber group, which is disposed at the circumference of the light projecting fiber, a second light receiving fiber group, which is disposed further on the outer side thereof, and photodetectors, which are connected to each of the fiber groups.
