Abstract
A container inspection system wherein diffused light and collimated light provide backlighting to image a container (10) by a color camera (18). Light strobed through a ring light (36) and parabolic reflector (39) is diffused at a diffusion laminate (46). Light strobed through a ring light (60) and parabolic reflector (64) is collimated at lens (68) and aligned with the diffused light by reflector laminate (48). Diffused light is filtered by a blue band-pass filter (42) and collimated light is filtered by a red band-pass filter (66) and camera (18) segregates the container image according to blue and red color planes.
