Digital Holographic Microscopy for the Life Sciences
Biomedical Optics and 3-D Imaging, 2012In the life sciences digital holographic microscopy provides high resolving, on-line, label-free, quantitative, multi-focus phase contrast imaging for the analysis of morphology dynamics and migration tracking in living cells.

Digital holographic microscopy applied to neurociences
2012 11th Euro-American Workshop on Information Optics, 2012Quantitative phase imaging techniques including digital holographic microscopy (DHM) have emerged recently in life sciences and can be aimed at monitoring and quantifying, in a non-invasive way, cellular processes. Due to its interferometric nature, the DHM phase signal or optical path difference (OPD), which depends on both cell thickness and integral

Digital Holographic Microscopy in the Presence of Refraction
Imaging and Applied Optics 2016, 2016Refraction poses a problem in digital holographic microscopy for samples with a high numerical aperture (NA). We present raytracing and acquisition close to the image plane to enable refraction corrected phase imaging of such samples.

Multiple-wavelength digital holographic microscopy
2009In this thesis work, we extend digital holographic microscopy (DHM) capabilities and applications range by using from two to twenty different wavelength laser sources, either simultaneously or sequentially. As an overview, we present methods to increase the measurement range to more than three decades, from demonstrated sub-nanometer precision to ...

Autofocus method in digital holographic microscopy
SPIE Proceedings, 2009The determination of focused image plane is the key of numerical reconstruction of wavefront. In this paper, three autofocus algorithms for digital holographic microscopy, including statistical algorithm, histogram-based algorithms and Fourier spectrum algorithm, are studied based on experimental investigation.

Multi-dimensional digital holographic microscopy
Optical Design and Testing VIII, 2018In this paper, we present a multi-dimensional digital holographic microscopy for biological applications. First, we present our concept of an optical microscopy that can produce both phase and fluorescence images. Then, a technique is demonstrated to obtain the three-dimensional distribution of fluorescence beads by a common-path off-axis incoherent ...

Broadband Digital Holographic Camera for Microscopy
2015In this thesis, we explore a combination of analog and digital holographic techniques to demonstrate high speed quantitative phase imaging (QPI) using low coherence (broad bandwidth) light sources. Off-axis digital holographic microscopy is inherently a coherent method of phase quantification and thus suffers from coherent noise.

An Introduction to Lensless Digital Holographic Microscopy
2018Digital Holographic Microscopy (DHM) is a technique that uses optical interference patterns to record a three-dimensional optical field for imaging, sensing, and microscopy applications. “Lensless” in-line DHM is the simplest arrangement, requiring no lenses, no mirrors, and typically only a light source, sample, and a digital imager chip such as a CCD
