Characterizing and tracking single colloidal particles with video holographic microscopy.
نویسندگان
چکیده
We use digital holographic microscopy and Mie scattering theory to simultaneously characterize and track individual colloidal particles. Each holographic snapshot provides enough information to measure a colloidal sphere's radius and refractive index to within 1%, and simultaneously to measure its three-dimensional position with nanometer in-plane precision and 10 nanometer axial resolution.

Holographic characterization of individual colloidal spheres’ porosities
Synthetic colloidal spheres play a central role in applications as diverse as catalysis, medical diagnostics, and photonics. Even as many applications advance toward single-sphere implementations, methods for characterizing colloidal spheres typically offer only sampleaveraged overviews of such properties as spheres’ sizes and porosities. Moreover, such characterization methods as mercury adsor...
متن کاملRobustness of holographic video microscopy against defects in illumination
We numerically investigate how defects in the illumination system of a holographic microscope, in particular divergence and tilt of the illuminating laser beam, affect the measured properties of colloidal spherical particles. We show that under typical experimental conditions divergence and tilt of the laser beam do not affect the measured parameters significantly, confirming the robustness of ...
متن کاملStrategies for three-dimensional particle tracking with holographic video microscopy.
The video stream captured by an in-line holographic microscope can be analyzed on a frame-by-frame basis to track individual colloidal particles' three-dimensional motions with nanometer resolution. In this work, we compare the performance of two complementary analysis techniques, one based on fitting to the exact Lorenz-Mie theory and the other based on phenomenological interpretation of the s...
متن کامل3D Localization of weak scatterers in digital holographic microscopy using Rayleigh-Sommerfeld back-propagation
The Rayleigh-Sommerfeld back-propagation method is a fast and highly flexible volume reconstruction scheme for digital holographic microscopy. We present a new method for 3D localization of weakly scattering objects using this technique. A well-known aspect of classical optics (the Gouy phase shift) can be used to discriminate between objects lying on either side of the holographic image plane....

The video stream captured by an in-line holographic microscope can be analyzed on a frame-by-frame basis to track individual colloidal particles' three-dimensional motions with nanometer resolution, and simultaneously to measure their sizes and refractive indexes. Through a combination of hardware acceleration and software optimization, this analysis can be carried out in near real time with of...
