ABSTRACT:
The present invention provides a device and a method for performing measurements on packagings, in particular packagings which are at least slightly worn on otherwise to a greater or lesser extent opaque to visible light, which are filled with a liquid product, wherein the packagings are irradiated with radiation in a wavelength range suitable for the packaging with product, and images of at least a part of the content of the packaging are recorded for a predetermined time by image recording means, wherein the obtained image information is analysed for information indicating the presence of undesired particles, and a part of the radiation has a frequency falling within the infrared range.
