Method and apparatus for inspecting full containers

A device for inspecting filled containers for foreign objects, the device comprising:

• a planar illumination device, the illumination device being configured to emit radiation which radiates through a container to be inspected,
• a detection device configured to detect the radiation which has been emitted by the illumination device and has radiated through the container, and to create an image of the container on the basis of the detected radiation, and
• an evaluation device configured to evaluate the image created by the detection device,
• wherein the detection device is aimed, such that the radiation emitted by the illumination device is reflected by total internal reflection at the bottom area of the container to be inspected and is imaged by the detection device, at an acute angle relative to the horizontal, at the bottom area of the container to be inspected, and
• wherein a foreign object located at the bottom of the container is recognized as a local disturbance in the recorded image.
