Simple wave-optical superpositions as prime number sieves
T. C. Petersen, M. Ceko, I. D. Svalbe +3
We encode the sequence of prime numbers into simple superpositions of identical waves, mimicking the archetypal prime number sieve of Eratosthenes. The primes are identified as zer…
A simple, pixel-wise response correction for ring artifact removal in both absorption and phase contrast X-ray computed tomography
Linda C. P. Croton, Gary Ruben, Kaye S. Morgan +2
We present a pixel-specific, measurement-driven correction that effectively minimizes errors in detector response that give rise to the ring artifacts commonly seen in X-ray comput…
Noise-resolution uncertainty principle in classical and quantum systems
Timur E. Gureyev, Alexander Kozlov, Yakov I. Nesterets +2
It is proved that the width of a function and the width of the distribution of its values cannot be made arbitrarily small simultaneously. In the case of ergodic stochastic process…
Aberrated dark-field imaging systems
Mario A. Beltran, David M. Paganin
We study generalized dark-field imaging systems. These are a subset of linear shift-invariant optical imaging systems, that exhibit arbitrary aberrations, and for which normally-in…
Single-Image Geometric-Flow X-Ray Speckle Tracking
David M. Paganin, Helene Labriet, Emmanuel Brun +1
We develop a speckle-tracking method for x-ray phase-contrast imaging, based on the concept of geometric flow. This flow is a conserved current associated with deformation of illum…
Determinantal polynomial wave functions induced by random matrices
Anthony Mays, Anita K. Ponsaing, David M. Paganin
Random-matrix eigenvalues have a well-known interpretation as a gas of like-charge particles. We make use of this to introduce a model of vortex dynamics by defining a time-depende…
