Phase Coherence Imaging

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2009
A new method for grating and side lobes suppression in ultrasound images is presented. It is based on an analysis of the phase diversity at the aperture data. Two coherence factors, namely the phase coherence factor (PCF) and the sign coherence factor (SCF), are proposed to weight the coherent sum output.

Coherent multistatic ISAR imaging

IET International Conference on Radar Systems (Radar 2012), 2012
This paper presents methods for Coherent Multistatic Radar Imaging for Non Cooperative Target Recognition (NCTR) with a network of radar sensors. Coherent Multistatic Radar Imaging is based on an extension of existing monostatic ISAR algorithms to the multistatic environment.

Fresnel Coherent Diffractive Imaging

Physical Review Letters, 2006
We present an x-ray coherent diffractive imaging experiment utilizing a nonplanar incident wave and demonstrate success by reconstructing a nonperiodic gold sample at 24 nm resolution. Favorable effects of the curved beam illumination are identified.

Coherent array optical imaging

Applied Optics, 1991
This paper describes a technique that allows a severely distorted coherent optical array receiver to produce images comparable to conventional monolithic imaging systems. The technique is based on using a phase synchronizing point source as a reference to eliminate phase errors in the array.
