Imaging complex objects using learning tomography

Michaël Unser, Alexandre Goy, Demetri Psaltis, Morteza Hasani Shoreh, Joowon Lim

Optical diffraction tomography (ODT) can be described using the scattering process through an inhomogeneous media. An inherent nonlinearity exists relating the scattering medium and the scattered field due to multiple scattering. Multiple scattering is oft ...

Phaseless Diffraction Tomography With Regularized Beam Propagation

Michaël Unser, Alexandre Goy, Demetri Psaltis, Thanh-An Michel Pham, Ferréol Arnaud Marie Soulez, Joowon Lim, Emmanuel Emilien Louis Soubies

In recent years, researchers have obtained impressive reconstructions of the refractive index (RI) of biological objects through the combined use of advanced physics (nonlinear forward model) and regularization. Here, we propose an adaptation of these tech ...

Optical Tomography Based On A Nonlinear Model That Handles Multiple Scattering

Michaël Unser, Alexandre Goy, Ulugbek Kamilov, Demetri Psaltis, Joowon Lim

Learning Tomography (LT) is a nonlinear optimization algorithm for computationally imaging three-dimensional (3D) distribution of the refractive index in semi-transparent samples. Since the energy function in LT is generally non-convex, the solution it obt ...
