An in-line holographic microscope is an optical microscope outfitted with a coherent light
source, such as a laser. Light scattered by the specimen interferes with the transmitted …

Machine learning is making a major impact in materials research. I review current progress
across a selection of areas of ubiquitous soft matter. When applied to particle tracking …

Holograms of colloidal particles can be analyzed with the Lorenz-Mie theory of light
scattering to measure individual particles' three-dimensional positions with nanometer …

We demonstrate how holographic video microscopy can be used to detect, count, and
characterize individual micrometer-scale protein aggregates as they flow down a …

In-line holographic microscopy provides an unparalleled wealth of information about the
properties of colloidal dispersions. Analyzing one colloidal particle's hologram with the …

Holograms of colloidal dispersions encode comprehensive information about individual
particles' three-dimensional positions, sizes and optical properties. Extracting that …

Holographic particle characterization uses in-line holographic video microscopy to track and
characterize individual colloidal particles dispersed in their native fluid media. Applications …

We describe colloidal Janus particles with metallic and dielectric faces that swim vigorously
when illuminated by defocused optical tweezers without consuming any chemical fuel …

The in-line hologram of a micrometer-scale colloidal sphere can be analyzed with the
Lorenz–Mie theory of light scattering to obtain precise measurements of the sphere's …

We introduce an image transform designed to highlight features with high degree of radial
symmetry for identification and subpixel localization of particles in microscopy images. The …
