X-ray sources are developing rapidly and their coherent output is growing correspondingly.
The increased coherent flux from modern X-ray sources is being matched with an …

The iterative Fourier-transform algorithm has been demonstrated to be a practical method for
reconstructing an object from the modulus of its Fourier transform (ie, solving the problem of …

In the generation of computer-generated holograms the phase is in many applications a free
parameter that can be manipulated to achieve a high diffraction efficiency, a small space …

A novel boundary detection scheme based on" edge flow" is proposed in this paper. This
scheme utilizes a predictive coding model to identify the direction of change in color and …

The purpose of this paper is to clarify the relationship between the isolated zero points in
modulus distribution and the least-squares phase estimation from the phase difference. The …

Most atmospheric-turbulence-compensation experiments have been performed under weak-
scintillation conditions; conventional phase-conjugate adaptive-optics systems usually …

Abstract SAR (Synthetic Aperture Radar) data focusing is analyzed from a theoretical point
of view. Two applications of a SAR data processing algorithm are presented, where the …

In Fourier and Fresnel holography diffuse illumination is used to smooth the power spectrum
of the object wave. A speckle pattern will then disturb the diffraction pattern. We present …

The design of diffractive phase elements (DPEs) for solving the general beam shaping
problem where the signal wave is specified by an intensity distribution on a continuous …

We discuss how we can obtain noniteratively an exact solution for the modified normal
equation in least-squares phase estimation from the measured phase difference. To achieve …
