Digital holographic reflectometry

Christian Depeursinge, Jonas Kühn, Tristan Colomb, Nicolas Pavillon, Ahmet Ata Akatay

Digital holographic microscopy (DHM) is an interferometric technique that allows real-time imaging of the entire complex optical wavefront (amplitude and phase) reflected by or transmitted through a sample. To our knowledge, only the quantitative phase is ...

Zero-Order-Free Image Reconstruction in Digital Holographic Microscopy

Michaël Unser, Christian Depeursinge, Nicolas Pavillon, Chandra Sekhar Seelamantula

We address the problem of zero-order-free image reconstruction in digital holographic microscopy. We show how the goal can be achieved by confining the object-wave modulation to one quadrant of the frequency domain, and by maintaining a reference-wave inte ...

Extended depth-of-focus by digital holographic microscopy

Christian Depeursinge, Jonas Kühn, Tristan Colomb, Nicolas Pavillon, Etienne Cuche

A recurrent problem in microscopy is the finite depth-of-focus linked to the NA of microscope objectives. Digital holographic microscopy (DHM) has the unique feature of being able to numerically change the focus from a single hologram without the need of m ...

Suppression of the zero-order in off-axis digital holography through nonlinear filtering

Michaël Unser, Christian Depeursinge, Jonas Kühn, Nicolas Pavillon, Chandra Sekhar Seelamantula

We present experimental validation of a new reconstruction method for off-axis digital holographic microscopy (DHM). This method effectively suppresses the object auto-correlation — namely the zero-order term — from holographic data, thereby improving the ...

Iterative method for zero-order suppression in off-axis digital holography

Christian Depeursinge, Nicolas Pavillon

We propose a method to suppress the so-called zero-order term in a hologram, based on an iterative principle. During the hologram acquisition process, the encoded information includes the intensities of the two beams creating the interference pattern, whic ...
