Abstract
An apparatus for detecting blisters in a container wall includes a light source for directing light energy onto a container wall in such a way that portions of the light energy are reflected from surfaces of the container wall, including surfaces of blisters in the container wall. A light sensor is disposed to receive light energy reflected from the container wall, and an information processor is coupled to the sensor to detect a blister in the container wall as a bright image against a darker background. Light energy reflected from the inner and outer surfaces of the container wall preferably establish the darker background, and light energy reflected from surfaces of blisters within the container wall establish the bright image.
