When topological derivatives met regularized Gauss-Newton iterations in holographic 3D imaging
A. Carpio, T. G. Dimiduk, F. Le Louer +1
We propose an automatic algorithm for 3D inverse electromagnetic scattering based on the combination of topological derivatives and regularized Gauss-Newton iterations. The algorit…
Active colloidal particles in emulsion droplets: A model system for the cytoplasm
Viva R. Horowitz, Zachary C. Chambers, İrep Gözen +2
In living cells, molecular motors create activity that enhances the diffusion of particles throughout the cytoplasm, and not just ones attached to the motors. We demonstrate initia…
Holographic Microscopy with Python and HoloPy
Solomon Barkley, Thomas G. Dimiduk, Jerome Fung +5
A holographic microscope captures interference patterns, or holograms, that encode three-dimensional (3D) information about the object being viewed. Computation is essential to ext…
Optimization methods for in-line holography
A. Carpio, T. G. Dimiduk, V. Selgas +1
We present a procedure to reconstruct objects from holograms recorded in in-line holography settings. Working with one beam of polarized light, the topological derivatives and ener…
Noninvasive imaging of three dimensional micro and nanostructures by topological methods
A. Carpio, T. G. Dimiduk, M. L. Rapun +1
We present topological derivative and energy based procedures for the imaging of micro and nanostructures using one beam of visible light of a single wavelength. Objects with diame…
Using the Discrete Dipole Approximation and Holographic Microscopy to Measure Rotational Dynamics of Non-spherical Colloidal Particles
Anna Wang, Thomas G. Dimiduk, Jerome Fung +4
We present a new, high-speed technique to track the three-dimensional translation and rotation of non-spherical colloidal particles. We capture digital holograms of micrometer-scal…
Imaging Multiple Colloidal Particles by Fitting Electromagnetic Scattering Solutions to Digital Holograms
Jerome Fung, Rebecca W. Perry, Thomas G. Dimiduk +1
Digital holographic microscopy is a fast three-dimensional (3D) imaging tool with many applications in soft matter physics. Recent studies have shown that electromagnetic scatterin…
