A method for creating an image of a base of a container uses a matrix camera. The matrix camera captures a series of individual captures of regions of the base of the container which overlap in sections, while the base of the container is transilluminated by a light source arranged on the side opposite the matrix camera. A digital image of the base of the container is compiled from the individual captures. The invention is characterized in that the region of the base of the container captured in an individual capture is defined by an illumination structure, that the illumination structure is shifted relative to the base of the container between two individual captures, and that the container and the matrix camera remain rotationally invariant to one another during the capturing of the series of individual captures. The invention also relates to a device for carrying out the method.

Methods and apparatus of inspection tools for inspecting impurities in vials are provided herein. In some embodiments, an inspection tool for inspecting impurities in vials includes: a motor; a plurality of carts configured to move via the motor to selectively place each of the plurality of carts in an inspection position, wherein each of the plurality of carts includes a vial holder configured to hold a plurality of vials, and wherein each vial holder is configured to spin the plurality of vials on their own respective axes; and a camera configured to take an image of at least one of the plurality of vials of a corresponding cart of the plurality of carts when the corresponding cart is disposed in the inspection position.

A device includes a camera, which captures images of moving objects, lighting units, and a controller. The camera captures recordings of the moving objects in series during transportation on the conveyor, so that a first recording of the object in a first position and a second recording of the object in a second position are obtained. The first and second positions of the object differ by the movement of the conveyor by a corresponding offset. The illumination units are composed of a dark-field illumination unit and a bright-field illumination unit, which are controlled synchronously with the camera by the controller such that the first recording generates a first contrast by a first specific control of the dark-field illumination unit and bright-field illumination unit, and in that the second recording generates a second contrast by a second specific activation of the dark-field illumination unit and bright-field illumination unit.

An optical measuring device having a polarization state generator to prepare a measuring light having a defined polarization state propagating along an analysis beam path, a receiving equipment arranged downstream of the polarization state generator to receive at least a first measuring cell and a second measuring cell, a polarization state analyzer arranged downstream of the receiving equipment, a detector for detecting an intensity of the measuring light, a stationary transmitting/receiving system to communicate with at least one of the first measuring cell and the second measuring cell and an evaluation and control unit for evaluating measuring signals from the detector and/or the polarization state analyzer and/or the polarization state generator taking into account information communicated between the stationary transmitting/receiving system and at least one of the two measuring cells.
