Abstract: A method for scanning a sample by means of X-ray optics for irradiating the sample with X-rays, comprises the following steps:
(a) displacing a measuring point, defined by an optical exit point of the X-ray optics, in the sample in a first scanning direction by means of swiveling the X-ray optics about a first swivel axis;
(b) detecting radiation emanating from the sample at, at least, two measuring points along the first scanning direction;
(c) combining measured values correlating with the detected radiation to form an overall scan.-

Abstract: An optical trap for laser cooling and trapping atoms. Three pairs of laser beams are directed to cross in a vacuum chamber at a common intersection volume, wherein each pair is formed by two counterpropagating beams. Rather than having a mutually orthogonal arrangement in which each beam pair forms an angle χ of 45° to a reference axis, z, these angles are instead between 5°≤χ≤40°. Moreover, in each beam pair, the counterpropagating beams are not precisely aligned in a common path, as in a conventional magneto-optical trap, but are slightly misaligned by respective misalignment angles [α, β, κ] of typically 0.1° to 2°. The misalignment angles and beam widths are however selected so that a common intersection volume for all six beams is maintained. This provides an all-optical trap in which laser cooling and trapping of atoms takes place without a magnetic field being present.

Abstract: A method and an X-ray apparatus generate a projective X-ray representation of an examination object. Two projective images obtained from a phase contrast measurement are adapted to each other in respect of their representation format and a result image is generated by combining the adapted images. The result image allows extensive separation of different structures in the examination object that is used.

Abstract: Provided is a radiation phase-contrast imaging device capable of assuredly detecting a self-image and precisely imaging the internal structure of an object. According to the configuration of the present invention, the longitudinal direction of a detection surface of a flat panel detector is inclined with respect to the extending direction of an absorber in a phase grating. This causes variations in the position (phase) of a projected stripe pattern of a self-image at different positions on the detection surface. This is therefore expected to produce the same effects as those obtainable when a plurality of self-images are obtained by performing imaging a plurality of times in such a manner that the position of the projected self-images on the detection surface varies. This alone, however, results in a single self-image phase for a specific region of the object. Therefore, according to the present invention, it is configured such that imaging is performed while changing the relative position of the imaging system and the object.

Abstract: The present invention relates to a method for producing an image of a target using radiation and a diffraction grating and apparatus for x-ray imaging. The method comprises directing a beam of radiation to the target to produce a modified beam through interaction with the target, directing the modified beam to an diffraction grating to produce an interference pattern, detecting the interference pattern using a detector, and forming an image of the target using the interference pattern measured. According to the invention, the diffraction grating is modified n the plane of the grating during the imaging so that at least two interference patterns are detected using the detector different configurations of the diffraction grating. Further, the image of the target using the at least two interference patterns measured. The invention provides a simple configuration, less radiation exposure and/or better image quality then conventional imaging methods.
