Abstract
A method and a device for inspecting containers and/or preforms. A scattering medium is provided in the interior of the containers or preforms and is irradiated in such manner that the scattering medium forms a bright field behind the container or preform wall area to be imaged. In this way, the wall area can easily be illuminated and imaged from different directions, so that inspection units can be created with a high degree of design freedom and with smaller dimensions.
