Imaging small polarizable scatterers with polarization data
Patrick Bardsley, Maxence Cassier, Fernando Guevara Vasquez
We present a method for imaging small scatterers in a homogeneous medium from polarization measurements of the electric field at an array. The electric field comes from illuminatin…
Quantitative Photoacoustic Imaging of Two-photon Absorption
Patrick Bardsley, Kui Ren, Rongting Zhang
Two-photon absorption photoacoustic tomography (TP-PAT) is a recent hybrid imaging modality that aims at reconstructing two-photon absorption properties of heterogeneous media from…
Criteria for guaranteed breakdown in two-phase inhomogeneous bodies
Patrick Bardsley, Michael S. Primrose, Michael Zhao +4
Lower bounds are obtained on the maximum field strength in one or both phases in a body containing two-phases. These bounds only incorporate boundary data that can be obtained from…
Kirchhoff migration without phases
Patrick Bardsley, Fernando Guevara Vasquez
We present a simple, frequency domain, preprocessing step to Kirchhoff migration that allows the method to image scatterers when the wave field phase information is lost at the rec…
Imaging with power controlled source pairs
Patrick Bardsley, Fernando Guevara Vasquez
Scatterers in a homogeneous medium are imaged by probing the medium with two point sources of waves modulated by correlated signals and by measuring only intensities at one single…
