Improving holographic particle characterization by modeling spherical aberration
Caroline Martin, Brian Leahy, Vinothan Manoharan
Holographic microscopy combined with forward modeling and inference allows colloidal particles to be characterized and tracked in three dimensions with high precision. However, cur…
Large depth-of-field tracking of colloidal spheres in holographic microscopy by modeling the objective lens
Brian Leahy, Ronald Alexander, Caroline Martin +2
Holographic microscopy has developed into a powerful tool for 3D particle tracking, yielding nanometer-scale precision at high frame rates. However, current particle tracking algor…
Biases in particle localization algorithms
Brian D. Leahy, Matthew Bierbaum, James Sethna +1
Automated particle locating algorithms have revolutionized microscopy image analysis, enabling researchers to rapidly locate many particles to within a few pixels in a microscope i…
How Confinement-Induced Structures Alter the Contribution of Hydrodynamic and Short-Ranged Repulsion Forces to the Viscosity of Colloidal Suspensions
Meera Ramaswamy, Neil Y. C. Lin, Brian D. Leahy +4
Understanding the correlation between structure and rheology in colloidal suspensions is important as these suspensions are crucial in industrial applications. Moreover, colloids e…
Light Microscopy at Maximal Precision
Matthew Bierbaum, Brian D. Leahy, Alexander A. Alemi +2
Microscopy is the workhorse of the physical and life sciences, producing crisp images of everything from atoms to cells well beyond the capabilities of the human eye. However, the…
A multi-axis confocal rheoscope for studying shear flow of structured fluids
Neil Y. C. Lin, Jonathan H. McCoy, Xiang Cheng +3
We present a new design for a confocal rheoscope that enables uniform uniaxial or biaxial shear. The design consists of two precisely-positioned parallel plates with a gap that can…
Visualization, coarsening and flow dynamics of focal conic domains in simulated Smectic-A liquid crystals
Danilo B. Liarte, Matthew Bierbaum, Muxin Zhang +3
Smectic liquid crystals vividly illustrate the subtle interplay of broken translational and orientational symmetries, by exhibiting defect structures forming geometrically perfect…
