摘要： Apparatus and methods for coherent diffractive imaging with arbitrary angle of illumination incidence utilize a method of fast remapping of a detected diffraction intensity pattern from a detector pixel array (initial grid) to a uniform spatial frequency grid (final grid) chosen to allow for FFT on the remapped pattern. This is accomplished by remapping the initial grid to an intermediate grid chosen to result in a final grid that is linear in spatial frequency. The initial grid is remapped (generally by interpolation) to the intermediate grid that is calculated to correspond to the final grid. In general, the initial grid (x,y) is uniform in space, the intermediate grid ({tilde over (x)},{tilde over (y)}) is non-uniform in spatial frequency, and the final grid ({tilde over (f)}x,{tilde over (f)}y) is uniform in spatial frequency.

摘要： The invention is a method and apparatus for performing a radiation scan of a structure (10) by arranging a source (18) of penetrating radiation and a radiation detector (20) at opposed ends of a radiation path through the structure, oriented in such a way that the source emits radiation along the path through the structure and the detector is capable of detecting the radiation after it has passed through the structure and monitoring the radiation emitted from the source that is detected by the detector; comprising mounting at least one continuous loop of a cable (16) on the structure between at least two fixed locations (22, 24) on said structure so that the cable is movable along its length relative to the structure, fixing at least one of the source of penetrating radiation and the radiation detector to the cable, arranging the other of the source and detector to emit radiation to or detect radiation from the source or detector that is fixed to the cable, monitoring the radiation received by the detector when the cable is in a first position, moving the cable along its longitudinal axis to move the source or detector fixed to the cable to a second position relative to said structure and monitoring the radiation received by the detector in the second position. Preferably both source and detector are fixed to the cable so that movement of the cable moves the source and detector by the same distance in the same direction.

摘要： An X-ray diffraction system uses a two-dimensional detector to detect diffracted X-ray energy at a plurality of radial positions surrounding a sample location, the results at each position being combined to form a final diffraction image. To minimize smearing in the final image, the detector pixel intensities at each position are reapportioned among the pixel locations prior to being combined with the intensities collected at other positions. A two-dimensional pixel array space of the detector is projected onto a cylinder to form a projected pixel array space, and a virtual cylindrical detection surface representative of an ideal cylindrical detector is determined. An overlap between the pixels of the projected pixel array space and the pixels of the virtual cylindrical detection surface is determined, and pixel intensities are reapportioned accordingly. The reapportionment may include dividing each pixel space into subpixels and redistributing the subpixels among adjacent pixels.

摘要： A process (130) for determining an actual shear angle (θ) between an interior wall (30) and a facesheet (22, 24) of a cellular panel (20) using an imaging system (40) is disclosed. The imaging system includes a radiation source (44) and a detector (46) diametrically opposed to the radiation source. The process includes positioning (132) the cellular panel at a tilt angle (φ) relative to a line (50) extending between the radiation source and the detector, transmitting (134) radiation from the radiation source to the detector through the cellular panel at the tilt angle to obtain an image (62), measuring (136) a projected shear angle (α) in the obtained image, and determining (138) the actual shear angle between the interior wall and the facesheet using the tilt angle and the projected shear angle.
