Abstract
An apparatus for inspecting sidewall thickness of non-round transparent containers includes a conveyor for holding a container in stationary position and rotating the container around an axis. A light source directs light energy onto a sidewall of the container on the conveyor. An anamorphic lens system having a lens system axis directs onto a light sensor energy reflected from portions of the inside and outside surfaces of the container sidewall that are substantially parallel to the lens system axis. An information processor is responsive to the sensor for determining sidewall thickness at increments of container rotation as a function of separation at the sensor between light energies reflected from the inside and outside surfaces of the container sidewall.
