Wavefront division digital holographic microscopy
Digital holographic microscopy is the state of the art quantitative phase imaging of micro-objects including living cells. It is an ideal tool to image and quantify cell thickness profiles with nanometer thickness resolution. Digital holographic techniques usually are implemented using a two-beam setup that may be bulky and may not be field portable ...

Characterizing and tracking single colloidal particles with video holographic microscopy
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 ...

We propose a single-shot digital holographic microscopy based on computational telecentricity with a single-arm off-axis interferometer (SA-OAI), which is composed of optical recording, computational compensation and retrieving processes.

Automatic cross filtering for off-axis digital holographic microscopy
Off-axis digital holographic microscopy (DHM) is a significant quantitative phase imaging (QPI) modality in a single shot. However, the reconstructed quality of the image in the off-axis DHM is governed by the spatial filtering in the spectral domain of ...

Multicascade-linked synthetic wavelength digital holography using an optical-comb-referenced frequency synthesizer [PDF]
Digital holography (DH) is a promising method for non-contact surface topography because the reconstructed phase image can visualize the nanometer unevenness in a sample.

Imaging in digital holographic microscopy
We present a theoretical formalism for three dimensional (3D) imaging properties of digital holographic microscopy (DHM). Through frequency analysis and visualization of its 3D optical transfer function, an assessment of the imaging behavior of DHM is given. The results are compared with those from other types of interference microscopy.

Opposite-view digital holographic microscopy with autofocusing capability
Digital holographic microscopy (DHM) has its intrinsic ability to refocusing a sample by numerically propagating an object wave from its hologram plane to its image plane.
