Quantitative phase and absorption contrast imaging
Miguel Moscoso, Alexei Novikov, George Papanicolaou +1
We present an algorithm for coherent diffractive imaging with phaseless measurements. It treats the forward model as a combination of coherent and incoherent waves. The algorithm r…
Fast signal recovery from quadratic measurements
Miguel Moscoso, Alexei Novikov, George Papanicolaou +1
We present a novel approach for recovering a sparse signal from cross-correlated data. Cross-correlations naturally arise in many fields of imaging, such as optics, holography and…
The Noise Collector for sparse recovery in high dimensions
Miguel Moscoso, Alexei Novikov, George Papanicolaou +1
The ability to detect sparse signals from noisy high-dimensional data is a top priority in modern science and engineering. A sparse solution of the linear system can be…
Imaging with highly incomplete and corrupted data
Miguel Moscoso, Alexei Novikov, George Papanicolaou +1
We consider the problem of imaging sparse scenes from a few noisy data using an -minimization approach. This problem can be cast as a linear system of the form , whe…
Synthetic aperture imaging with intensity-only data
Miguel Moscoso, Alexei Novikov, George Papanicolaou +1
We consider imaging the reflectivity of scatterers from intensity-only data recorded by a single moving transducer that both emits and receives signals, forming a synthetic apertur…
Robust multifrequency imaging with MUSIC
Miguel Moscoso, Alexei Novikov, George Papanicolaou +1
In this paper, we study the MUltiple SIgnal Classification (MUSIC) algorithm often used to image small targets when multiple measurement vectors are available. We show that this al…

We present a comprehensive study of the resolution and stability properties of sparse promoting optimization theories applied to narrow band array imaging of localized scatterers.…
Coherent imaging without phases
Miguel Moscoso, Alexei Novikov, George Papanicolaou
In this paper we consider narrow band, active array imaging of weak localized scatterers when only the intensities are recorded at an array with N transducers. We consider that the…
Synthetic Aperture Imaging of Direction and Frequency Dependent Reflectivities
Liliana Borcea, Miguel Moscoso, George Papanicolaou +1
We introduce a synthetic aperture imaging framework that takes into consideration directional dependence of the reflectivity that is to be imaged, as well as its frequency dependen…
Illumination strategies for intensity-only imaging
Alexei Novikov, Miguel Moscoso, George Papanicolaou
We propose a new strategy for narrow band, active array imaging of localized scat- terers when only the intensities are recorded and measured at the array. We consider a homogeneou…
A differential equations approach to -minimization with applications to array imaging
Miguel Moscoso, Alexei Novikov, George Papanicolaou +1
We present an ordinary differential equations approach to the analysis of algorithms for constructing minimizing solutions to underdetermined linear systems of full rank. It…
