Two-step distortion-free reconstruction scheme for holographic microscopy [PDF]

open access: yesDigital Holography and Three-Dimensional Imaging, Kohala Coast, Hawaii : France (2013), 2013
We propose a three-dimensional holographic reconstruction procedure applicable with no a priori knowledge about the recording conditions enabling distortion-free three-dimensional object reconstruction.

Automatic Spatial Filtering by Combining Wavelet-Transform Modal Maxima and Mathematical Morphology in Digital Holographic Microscopy

open access: yesPhotonics, 2023
Digital holographic microscopy has significant advantages over traditional 3D measurements. In order to obtain a reconstructed image of superior quality, the zero-order-term spectrum and the −1 term spectrum must be eliminated during the digital ...

An Inexpensive Portable Self-Reference Module for Digital Holographic Microscopy

open access: yesPhotonics, 2021
This paper describes a novel optical system that can be integrated to the image port of an existing brightfield microscope in order to enhance the microscope with the features of digital holographic microscopy. The proposed system is modular and portable.

Characterizing and tracking single colloidal particles with video holographic microscopy [PDF]

open access: yes, 2007
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 ...
