A sample inspection system contains a source of electromagnetic radiation and an apparatus that includes a beam former, a collimator and an energy resolving detector. The beam former is adapted to receive electromagnetic radiation from the source to provide a polygonal shell beam formed of at least three walls of electromagnetic radiation. The collimator has a plurality of channels adapted to receive diffracted or scattered radiation at an angle. The energy resolving detector is arranged to detect radiation diffracted or scattered by a sample upon incidence of the polygonal shell beam onto the sample and transmitted by the collimator.

A method of manufacturing a film (F1) including cavities and formed from a polymer in which a cavitating agent is dispersed, said method including a step of extruding the polymer through an extrusion die equipped with adjustment actuators for adjusting thickness of the extruded film, and a step of stretching (Str1) the film, as well as establishing a mapping function of the film on the basis of mass-per-unit-area profiles of the film before and after the stretching step, establishing a stretch profile of the film as stretched on the basis of said mapping function and of said transverse mass-per-unit-area profiles, and establishing a characteristic transverse profile that is characteristic of the film on the basis of said stretch profile and of a transverse profile of the concentration by mass of cavitating agent in the film as stretched that makes it possible to take into account the distribution of the cavities in the film; in which method said adjustment actuators are controlled as a function of said characteristic transverse profile.

A method of detecting a defect in a wind turbine blade uses a system that includes an X-ray generator, moved by a first transporting means, that generates X-ray to be irradiated to the wind turbine blade; an X-ray detector, moved by a second transporting means, that detects the X-ray generated by the X-ray generator and transmitted through the wind turbine blade; and a control unit. To detect a defect, the control unit divides virtually the wind turbine blade into a plurality of lengthwise sections based on a thickness profile thereof, receives a location of the X-ray generator, and controls output of the X-ray generator based on the location of the X-ray generator relative to the plurality of lengthwise sections. In particular, the output of the X-ray generator is decreased for a section among the plurality of lengthwise sections that is farther from a hub of the wind turbine blade.

6Examples described herein provide a method that includes obtaining, by a processing device, three-dimensional (3D) voxel data. The method further includes performing, by the processing device, gray value thresholding based at least in part on the 3D voxel data and assigning a classification value to at least one voxel of the 3D voxel data. The method further includes defining, by the processing device, segments based on the classification value. The method further includes filtering, by the processing device, the segments based on the classification value. The method further includes evaluating, by the processing device, the segments to identify a surface voxel per segment. The method further includes determining, by the processing device, a position of a surface point within the surface voxel.

A method for the X-ray inspection of products of a predefined product type including at least one first component and one second component having different absorption coefficients for X-radiation. X-radiation with a spectral range is transmitted through a product to be examined. The X-radiation that has passed through the product is detected by means of a spectrally resolving X-ray detector. The spectrally resolving X-ray detector assigns the X-ray quanta to a number of energy channels and generates image data which for each pixel include spectral values for selected or all energy channels and/or total spectral values for one or more groups of adjacent energy channels. At least one mapping rule is used to process the image data to form a total image, where each mapping rule is designed such that spectral values or total spectral values are mapped onto a total image value of an image point.

A system and method for the accurate determination of a time to fire high energy radiation for security inspection of a cargo vehicle in a drive-through inspection portal. The system includes at least two sensors, one of which is positioned at an entry to the portal, and the other is positioned just after beamline center (BCL). As a driver of the vehicle activates a button at the entry to the portal, the system takes a measurement using one sensor to determine a distance from the driver to a front of the vehicle. As the vehicle reaches the BCL, a measurement is taken by the other sensor in real time and compared with the measurement taken at the entry. A user defined offset is then applied to determine how far behind the driver should the high energy radiation be fired.

In one embodiment, an X-ray inspection system may access a first set of X-ray images of one or more first samples that are labeled as being non-conforming. The system may adjust a classification algorithm based on the first set of X-ray images. The classification algorithm may classify samples into conforming or non-conforming categories based on an analysis of corresponding X-ray images. The system may analyze a second set of X-ray images of a number of second samples using the adjusted classification algorithm. The second samples may be previously inspected samples that have been classified as conforming by the classification algorithm during a previous analysis before the classification algorithm is adjusted. The system may identify one or more of the second samples from the second set of X-ray images. Each identified second sample may be classified as non-conforming by the adjusted classification algorithm.
