A method of observing and analyzing optical singularities includes illuminating an outside of a container by using a light-emitting surface of axial symmetry around a vertical axis (Z) parallel to the axes of symmetry of the containers, with a property of the emission that is detectable by the acquisition system(s) varying along a generator line of the light-emitting surface. For containers of low transmittance, taking the view image of the container portion by the image acquisition device receiving light beams comes from a portion of the light-emitting surface situated on the same side of the container. For containers of high transmittance, taking the view of the container portion by the image acquisition device receiving light beams comes from a portion of the light-emitting surface that is diametrically opposite relative to the container.

The disclosure relates to a method for optically inspecting containers, wherein the containers are transported to an inspection unit with an illumination unit and with a camera, wherein the illumination unit emits light from a flat light-emitting surface, wherein the light is transmitted or reflected via the containers, wherein the camera captures a respective at least one of the containers and the light transmitted or reflected via same in at least one camera image, and wherein the at least one camera image is analysed by an image processing unit for intensity information in order to identify foreign bodies and/or defects in the container.

A system for inspecting a glass container and methods of inspecting glass containers are provided. The system includes a panel including a plurality of light sources configured to illuminate the glass container. The system includes a camera configured to image the illuminated glass container. The system includes a controller configured to adjust the amount of power applied to each of the light sources individually.

To provide a means that is less likely to misidentify a crack as a foreign substance during an image checking in which a vibration is applied to a powder contained in a bag-like container. A foreign substance checking system includes a vibration device configured to apply a vibration to a container, a photography device configured to optically photograph the inside of the container through a transparent region from the outside, and a determination device configured to determine whether a foreign substance is present inside the container based on an image of the container photographed by the photography device. The vibration device includes a rotating shaft and a hammer rotating in conjunction with the rotating shaft and colliding with the container. A portion of an outer surface of the hammer to abut on the container has a flat surface.

An apparatus for inspecting containers includes a rotation device which is adapted to rotate the container about the axis of symmetry; a camera sensitive to said predetermined electromagnetic radiation and with the container located in the field of view thereof; a processing unit to control the rotation device to move the container at a first angular speed constant for a first time period; acquiring at least a first and a second series of images of a portion of the container in a rotation thereof through 360°; to identify defective areas having at least one characteristic different from the characteristics of adjacent areas, generating first and second maps of the defective areas; to compare the position of the defective areas of the maps; to establish that first impurities are present in the container or in the liquid contained in the container.

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.

An inspection system having a light source, a mirror sensor, and an image sensor. The mirror assembly is aligned with the camera; the light is reflected from the container to the camera, and the camera creates multiple images of the container at a viewing angle. The multiple images are analyzed to detect defects.

The invention relates to a method for optically testing containers, in which a container (10) is conveyed by means of a transport device (30), whereby an image of a side wall surface of the container (10) is generated by means of an inspection unit (40) comprising a camera unit (20) and an illumination unit (34). An inspection volume (24) is spanned by several correspondingly arranged inspection units (40), in which an image of the entire side wall surface (26) of the container (10) is generated in a transmitted light method, an incident light method and/or a dark-field method.

An umbilicus-driven centrifuge includes a yoke configured to orbit a midsection of the umbilicus around a rotational axis at a first speed so as to cause a separation chamber associated with the umbilicus to rotate about the rotational axis at a second speed that is approximately double the first speed. An optical monitoring system directly monitors the separation chamber, with a light source oriented to emit light toward the separation chamber and a light detector oriented to receive at least a portion of the light after the light has passed through the separation chamber. A controller receives a plurality of signals from the light detector, then compares the period or frequency of the signals to an expected period or frequency. The controller determines that the umbilicus is experiencing an irregularity when the period or frequency is different from the expected period or frequency.

An inspection system having a light source able to illuminate a transparent cylinder, a mask able to block at least part of the light from the light source, the light source and the mask arranged such that, when the transparent cylinder is positioned in the system for inspection, the light source, the mask and the transparent cylinder are substantially aligned along an inspection axis perpendicular to the longitudinal axis of said transparent cylinder and the mask is interposed between the light source and the transparent cylinder to prevent illumination of a first portion of the transparent cylinder having a width smaller than the diameter of the transparent cylinder while allowing illumination of a second portion of the transparent cylinder, the mask configured to provide a contrast with a particle present in the first portion of the cylinder and illuminated by light refracted by the second portion of the cylinder.
