The light source is operable in a first mode to illuminate one end of at least some of the openings, and operable in a second mode to illuminate the opposed end of the at least some of the openings. The camera is operable to capture a first image of the at least some of the openings simultaneously with the light source being operated in the first mode, and a second image of the at least some of the openings simultaneously with the light source being operated in the second mode.
