Claim:
A system for imaging an interior surface of at least one substantially cylindrical object, said system comprising: a substantially cylindrical illuminator, positioned substantially to one side of an opening of a substantially cylindrical object to be imaged, to illuminate at least a portion of said interior surface of said substantially cylindrical object, wherein said substantially cylindrical illuminator includes a plurality of light emitting diodes (LEDs) arranged in rows, and wherein axes of illumination of said LEDs are pointed downward at predefined elevation angles with respect to horizontal such that each of said rows corresponds to a different predefined elevation angle; a truncated conical mirror positioned substantially within an open interior region of said substantially cylindrical illuminator to reflect an image of at least a portion of said interior surface of said substantially cylindrical object; and a single camera positioned substantially to one side of said substantially cylindrical illuminator and said truncated conical mirror to capture a single image of at least said interior surface of said substantially cylindrical object via light reflected at least directly from at least a portion of said interior surface of said substantially cylindrical object to said camera and from said truncated conical mirror to said camera.
