ABSTRACT
Recently, Wolf has shown that the phase measurement associated with fields that are not monochromatic, which is relevant for all x-ray structure investigations, must be properly defined via a cross-spectral density function under full spatial coherence conditions; otherwise, the problem is meaningless and has no solution [E. Wolf, Phys. Rev. Lett. 103, 075501 (2009)]. We propose an experimental realization for retrieving the phase across the entire field of an image. The demonstration is performed using broadband optical fields, but can be extended to other electromagnetic radiation, including x-rays.

    Described here is a repetitively pulsed, flash x-ray source capable of emitting 35-mW average power in 6-ns pulses of radiation near 1.5 A. From this device a significant fraction of the output is represented by the K lines of copper, so that in less than 1 min of experimental time a peak...

    We analyze multicolor observations of the blazar ON 231 obtained during coordinated observations in 1994–2002. On average, the spectral energy distribution of the variable component in the optical range remains constant, and can be represented by the power law Fν∼ ν-0.85. Since...

The apparent universality of accretion-related outflow phenomena is a strong indicator that large-scale MHD torques...

    A total reflection x-ray mirror is fabricated with a new method called as “bent-polishing”. Focusing properties of a microbeam are evaluated at undulator beamline BL47XU of SPring-8. The measured focal spot size is 0.16 μm at an x-ray energy of 8 keV. Spot size of smaller than 0.5...

    We demonstrate the feasibility of phase-contrast imaging with an ultrafast laser-based hard x-ray source. Hard x rays are generated during the interaction of a high-intensity femtosecond laser pulse (10 TW, 60 fs, 10 Hz) focused onto solid target in a very small spot (3 μm diam). Such a novel...

    Aberrations of rays reflected in a Cauchois scheme are considered on the basis of geometrical concepts of propagation of X-rays. It is shown that geometrical aberration can exceed the Borman delta width as well as the diffraction width of the focus. To reduce the influence of aberrations, the...

    We present a theoretical analysis of optical properties of parabolic compound refractive lenses (CRL). The parabolic CRL with a large number of elements is considered as a parabolic medium along the x-ray path. The problem of x-ray coherent wave propagation inside such a medium is solved...
