White paper: Blind Corners in Round Glass.

In general glass is transparent over its whole area or volume. But especially in curved glass this is not the case.
In glass with a cylinder or ball shape there are blind areas, so no light travels through that area.
If possible when a light source is placed in that area no light will reach you eye.

Therefor defects in that blind area will not be seen by the eye or a camera.
Quality inspection of glass by an automatic vision inspection system can not inspect the whole area in one image. Blind Corners in Round Glass
This paper shows the blind areas and give some solution to inspect the whole area or volume of curved glass.
