• the image capture system can generate the at least one image as the diffused light passes through a sidewall of the glass container.
• the at least one image may include a view of the portion of the container reflected by a mirror.
• the glass container inspection system yet further includes a computing system in communication with the image capture system.
• the computing system can be configured to output an indication as to whether the container is defective based upon the data from the image capture system.
• the computing system can be further configured to output the indication responsive to detecting a check in the sidewall of the glass container.
• a method of forming the container inspection system includes arranging a diffuse illuminator to illuminate a portion of a glass container with diffuse light.
• the method further includes arranging a mirror to reflect a portion of the glass container illuminated by the diffuse illuminator.
• a conveyor 102 transports a plurality of glass containers 104-106 through the container inspection system 100.
• the container inspection system 100 comprises an illuminator 108 configured to emit light to illuminate the plurality of glass containers 104-106 as they travel through the container inspection system 100.
• the container inspection system 100 also comprises an image capture system 110 configured to capture one or more images of each of the plurality of glass containers 104-106 as the plurality of glass containers 104-106 are transported through the container inspection system 100 by the conveyor 102.
• the image capture system 110 can be configured to capture the image(s) during illumination of each container by the illuminator 108, as will be described in detail below.
