Fermi pencil beams and off-axis laser detection
Guillaume Bal, Benjamin Palacios
This paper concerns the reconstruction of properties of narrow laser beams propagating in turbulent atmospheres. We consider the setting of off-axis measurements, based on light de…
Photoacoustic tomography in attenuating media with partial data
Benjamin Palacios
The attenuation of ultrasound waves in photoacoustic and thermoacoustic imaging presents an important drawback in the applicability of these modalities. This issue has been address…
Pencil-beam approximation of fractional Fokker-Planck
Guillaume Bal, Benjamin Palacios
We consider the modeling of light beams propagating in highly forward-peaked turbulent media by fractional Fokker-Planck equations and their approximations by fractional Fermi penc…
Pencil-beam approximation of stationary Fokker-Planck
Guillaume Bal, Benjamin Palacios
Solutions of stationary Fokker-Planck equations in the narrow beam regime are commonly approximated by either ballistic linear transport or by a Fermi pencil-beam equation. We pres…
Mathematical Modeling for 2D Light-Sheet Fluorescence Microscopy image reconstruction
Evelyn Cueva, Matias Courdurier, Axel Osses +3
We study an inverse problem for Light Sheet Fluorescence Microscopy (LSFM), where the density of fluorescent molecules needs to be reconstructed. Our first step is to present a mat…
Quantitative analysis of metal artifacts in X-ray tomography
Benjamin Palacios, Gunther Uhlmann, Yiran Wang
In X-ray CT scan with metallic objects, it is known that direct application of the filtered back-projection (FBP) formula leads to streaking artifacts in the reconstruction. These…
