We show how to propagate some fields, in particular a Bessel field, a superposition of Airy beams, both over the square root of the radial coordinate, and show how to construct a field that reproduces itself periodically in propagation, i.e., a field that renders the Talbot effect. ...

Metrics Abstract Material-selective analysis of spectral X-ray imaging data requires prior knowledge of the energy dependence of the observed signal. Contrary to conventional X-ray imaging, where the material-specific attenuation coefficient is usually precisely known, the linear diffusion coefficient of ...
5(b). As mentioned above, the sample speed of 5 mm/s corresponds to 1 pixel/frame; therefore, the effect of motion blur is not a concern below this speed in the x-direction. Actually, the spatial resolution near the Nyquist limit was attained below 5 mm/s, and clear degradation ...
