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.

An insulated electrical component (10) of an insulated electrical machine includes a conducting element (12), a first radiographically-visible conductor sensor node (16) coupled to the conducting element (12), at least one second radiographically-visible conductor sensor node (16) coupled to the conducting element (12) a first distance in a predetermined direction from the first radiographically-visible conductor sensor node (16), and an insulating material (14) bonded to the conducting element (12). In some embodiments, the insulated electrical component (10) further includes a first radiographically-visible insulator sensor node (40) coupled to the insulating material (14) and not coupled to the conducting element (12) and at least one second radiographically-visible insulator sensor node (40) coupled to the insulating material (14) and not coupled to the conducting element (12) a second distance from the first radiographically-visible insulator sensor node (40). The radiographically-visible sensor nodes (16, 40) are distinguishable from the conducting element (12) and the insulating material (14) in a radiographic image. Methods of manufacturing and non-destructive testing of insulated electrical components (10) are also disclosed.

A radiation image acquisition device includes: a radiation source which emits radiation; a wavelength conversion member of a flat plate shape which generates scintillation light according to incidence of the radiation emitted from the radiation source and transmitted by an object; first imaging means which condenses and images the scintillation light emitted from an entrance surface for the radiation in the wavelength conversion member in a direction of a normal to the entrance surface; and second imaging means which condenses and images the scintillation light emitted from a surface opposite to the entrance surface in the wavelength conversion member in a direction of a normal to the opposite surface.

The invention describes a method for inspecting samples in an electron microscope. A sample carrier 500 shows electrodes504, 507 connecting pads 505, 508 with areas A on which the sample is to be placed. After placing the sample on the sample carrier, a conductive pattern is deposited on the sample, so that voltages and currents can be applied to localized parts of the sample. Applying the pattern on the sample may be done with, for example, Beam Induced Deposition or ink-jet printing. The invention also teaches building electronic components, such as resistors, capacitors, inductors and active elements such as FET's in the sample.
