Broadband Digital Holographic Camera for Microscopy

In 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 co ...

Off-axis digital holographic camera for quantitative phase microscopy

Christian Depeursinge, Christophe Moser, Frédéric Montfort, Zahra Monemhaghdoust

We propose and experimentally demonstrate a digital holographic camera which can be attached to the camera port of a conventional microscope for obtaining digital holograms in a self-reference configuration, under short coherence illumination and in a sing ...

Quantitative phase noise in a two-color low coherence Digital Holographic Microscope

Christian Depeursinge, Christophe Moser, Zahra Monemhaghdoust, Frédéric Montfort

In digital holographic microscopy (DHM), the long coherence length of laser light causes parasitic interferences due to multiple reflections in and by optical components in the optical path of the microscope and thus degrades the image quality. The parasit ...

Dual wavelength full field imaging in low coherence digital holographic microscopy

Christian Depeursinge, Christophe Moser, Zahra Monemhaghdoust, Frédéric Montfort

A diffractive optical element (DOE) is presented to simultaneously manipulate the coherence plane tilt of a beam containing a plurality of discrete wavelengths. The DOE is inserted into the reference arm of an off-axis dual wavelength low coherence digital ...
