Digital in-line holographic microscopy

Applied Optics, 2006
We first briefly review the state of the art of digital in-line holographic microscopy (DIHM) with numerical reconstruction and then discuss some technical issues, such as lateral and depth resolution, depth of field, twin image, four-dimensional tracking, and reconstruction algorithm.

Holographic point source for digital lensless holographic microscopy

Optics Letters, 2022
A holographic point source (HPS) developed for digital lensless holographic microscopy (HPS-DLHM) is presented. The HPS is an off-axis phase transmission hologram of an experimental micrometer pinhole recorded on a photopolymer holographic film. An amplitude division interferometer, adjusted to operate at maximum diffraction efficiency, has been ...

In-line digital holographic imaging in volume holographic microscopy

Optics Letters, 2015
A dual-plane in-line digital holographic imaging method incorporating volume holographic microscopy (VHM) is presented to reconstruct objects in a single shot while eliminating zero-order and twin-image diffracted waves. The proposed imaging method is configured such that information from different axial planes is acquired simultaneously using ...

Optical Tomography by Digital Holographic Microscopy

Novel Optical Instrumentation for Biomedical Applications IV, 2009
Optical tomography provides three-dimensional data of the measured specimen, while quantitative phase imaging enables measuring the induced phase-shifts. Combining those two technologies makes possible to get three-dimensional refractive index reconstruction.

Compressed sensing for digital holographic microscopy

2010 IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2010
This paper describes an original microscopy imaging framework successfully employing Compressed Sensing for digital holography. Our approach combines a sparsity minimization algorithm to reconstruct the image and digital holography to perform quadrature-resolved random measurements of an optical field in a diffraction plane.

Digital holographic microscopy applied to metrology

SPIE Proceedings, 2004
We report on a method called Digital Holographic Microscopy (DHM) for the numerical reconstruction of digital holograms taken with a microscope. It allows for simultaneous amplitude and quantitative phase contrast imaging. The reconstruction method computes the propagation of the complex optical wavefront diffracted by the object and is used to ...

Recent Advances in Digital Holographic Microscopy

2018 20th International Conference on Transparent Optical Networks (ICTON), 2018
In digital holographic microscopy (DHM) a hologram is captured in the image space provided by a microscope. The transfer of the phase and amplitude structure in the original sample to the hologram is in fact strongly affected by the use of the imaging microscope.
