Characterisation of photonic crystal and nanophotonics devices with Fourier optics

Romuald Houdré, Nicolas Le Thomas, Jana Jágerská

We report on the experimental investigation of the Floquet-Bloch modes propagation inside photonic crystal (PhC) structures as well as their emission from the structures with far-field optics. We demonstrate that far-field optical experiments can be used t ...

Extended focus Fourier domain optical coherence microscopy and fluorescence lifetime imaging

Theo Lasser, Rainer Leitgeb, Martin Villiger, Adrian Bachmann, Cédric Blatter

Fourier domain Optical coherence microscopy (FDOCM) offers excellent sensitivity and high axial resolution to image the structure of biological tissue. The depth information is extracted in parallel and allows very high volume acquisition rates. An illumin ...

Subspace-Based Methods for Image Registration and Super-Resolution

Martin Vetterli, Loïc Arnaud Baboulaz, Patrick Vandewalle, Pier Luigi Dragotti

Super-resolution algorithms combine multiple low resolution images into a single high resolution image. They have received a lot of attention recently in various application domains such as HDTV, satellite imaging, and video surveillance. These techniques ...

Groebner Basis Methods for Multichannel Sampling with Unknown Offsets

Martin Vetterli, Luciano Sbaiz, Patrick Vandewalle

In multichannel sampling, several sets of sub-Nyquist sampled signal values are acquired. The offsets between the sets are unknown, and have to be resolved, just like the parameters of the signal itself. This problem is nonlinear in the offsets, but linear ...

Sound Field Analysis Along a Circle and its Application to HRTF Interpolation

Martin Vetterli, Christof Faller, Luciano Sbaiz, Thibaut Ajdler

The sampling and interpolation of a sound field in two and three dimensions along a circle is discussed. The Fourier domain representation of the sound field is used, and an angular sampling theorem is developed for the sampling of the sound field along a ...

Advantages of digital holographic microscopy for real-time full field absolute phase imaging

Christian Depeursinge, Tristan Colomb, Pierre Marquet, Jonas Kühn, Florian Charrière

Different interferometric techniques were developed last decade to obtain full field, quantitative, and absolute phase imaging, such as phase-shifting, Fourier phase microscopy, Hilbert phase microscopy or digital holographic microscopy (DHM). Although, th ...

Wavelets on Graphs via Spectral Graph Theory

Pierre Vandergheynst, Rémi Gribonval

We propose a novel method for constructing wavelet transforms of functions defined on the vertices of an arbitrary finite graph. We define a notion of scaling using the graph analogue of the Fourier domain, namely the space of eigenfunctions forming the sp ...

Frequency encoded assessment of retinal physiology - art. no. 684401

Theo Lasser, Rainer Leitgeb, Adrian Bachmann, Roland Michaely, Cédric Blatter

We demonstrate in-vivo functional imaging of the human retina with Fourier domain optical coherence tomography employing frequency encoding of an excitation pattern. The principle is based on projecting a modulated rectangular pattern across the foveal reg ...
