Abstract:
In a system for inspecting light-transmissive containers, apparatus for generating an image signal in response to a timing signal, said apparatus comprising:a first light generator that emits light within a first predetermined frequency bandwidth in response to a timing signal;a diffusion element that is illuminated by light emitted from said first light generator and that produces diffused light in response to light from said first light generator;a second light generator that emits collimated light within a second predetermined frequency bandwidth in response to a timing signal; anda camera having a lens that is illuminated by diffused light from said diffusion element and that is also illuminated by collimated light from said second light generator, said camera having a first imaging means that generates an image signal in response to the diffused light within said first frequency bandwidth and having a second imaging means that generates an image signal in response to the collimated light within said second frequency bandwidth.
