Simulation of Decoherence in Fluctuation Electron Microscopy

Fluctuation Electron Microscopy (FEM) examines the scattering statistics from small volumes of thin amorphous materials to detect the presence of medium-range order (MRO) [1]. By now it has been thoroughly demonstrated, by both modeling and simulations, that FEM is extraordinarily sensitive to MRO, much more than high-resolution diffraction and high-resolution imaging. Experiments have confirme...

Singularities in Speckled Speckle: Statistics

Random optical fields with two widely different correlation lengths generate far field speckle spots that are themselves highly speckled. We call such patterns speckled speckle, and study their critical points (singularities and stationary points) using analytical theory and computer simulations. We find anomalous spatial arrangements of the critical points and orders of magnitude anomalies in ...

Scanning quantum decoherence microscopy.

The use of qubits as sensitive nanoscale magnetometers has been studied theoretically and recently demonstrated experimentally. In this paper we propose a new concept, in which a scanning two-state quantum system is used to probe a sample through the subtle effects of decoherence. Mapping both the Hamiltonian and decoherence properties of a qubit simultaneously provides a unique image of the ma...

Intravascular Ultrasound Speckle Statistics

A ridge based speckles segmentation algorithm is proposed for segmenting speckle images and its application in IVUS (intrascular ultrasound) images is studied. An IVUS image may be treated as a height map and its ridges correspond to the center of the speckles. Author proposed a ridge detection algorithm based on the calculation of the maximum ascent direction. The algorithm’s running time is l...
