Standing wave integrated Fourier transform spectrometer for imaging spectrometry in the near infrared

Hans Peter Herzig, Gaël David Osowiecki, Irène Antoinette Philipoussis, Mohammadreza Madi, Toralf Scharf

We show the miniaturization and parallelization of a scanning standing wave spectrometer with a long term goal of creating a compact imaging spectrometer. In our standing wave integrated Fourier transform spectrometer, light is injected with micro-lenses i ...

Determination of sulfonylurea herbicides in surface water using polar organic chemical integrative samplers (POCIS)

Dominique Grandjean, Luiz Felippe De Alencastro, Nicolas Estoppey

Sulfonylurea herbicides represent new pollutants of growing concern, which requires their continuous monitoring in the aquatic environment. Widely used for pre and post emergence control of broadleaf and grassy weeds in different crops, designed to offer a ...

3D, LTCC-type, high-frequency magnetic sensors for the TCV Tokamak

Duccio Testa, Matthieu Toussaint, Gaël André Léon Farine, Thomas Maeder, Caroline Jacq, Adrien Aymeric Thibault Corne

High-frequency, 3D magnetic sensors have been designed and manufactured in-house for installation on the Tokamak a Configuration Variable (TCV). To optimize the in-vessel volume occupation, the sensors are based on combining the Low Temperature Co-fired Ce ...

Approximation Properties Of Sobolev Splines And The Construction Of Compactly Supported Equivalents

Michaël Unser, John Paul Ward

In this paper, we construct compactly supported radial basis functions that satisfy optimal approximation properties. Error estimates are determined by relating these basis functions to the class of Sobolev splines. Furthermore, we derive new rates for app ...

Sampling based on timing: Time encoding machines on shift-invariant subspaces

Martin Vetterli, David Gontier

Sampling information using timing is an approach that has received renewed attention in sampling theory. The question is how to map amplitude information into the timing domain. One such encoder, called time encoding machine, was introduced by Lazar and To ...

Sampling Curves with Finite Rate of Innovation

Thierry Blu, Hanjie Pan, Pier Luigi Dragotti

In this paper, we extend the theory of sampling signals with finite rate of innovation (FRI) to a specific class of two-dimensional curves, which are defined implicitly as the zeros of a mask function. Here the mask function has a parametric representation ...

Compact Low-Power Cortical Recording Architecture for Compressive Multichannel Data Acquisition

Pierre Vandergheynst, Alexandre Schmid, Mahsa Shoaran, Mahdad Hosseini Kamal

This paper introduces an area- and power-efficient approach for compressive recording of cortical signals used in an implantable system prior to transmission. Recent research on compressive sensing has shown promising results for sub-Nyquist sampling of sp ...

Beating Shapes Relying on Moire Level Lines

Roger Hersch, Sylvain Chosson

We consider the problem of obtaining a recognizable shape as superposition moire of two line gratings. The method we propose generates moire lines located between the shape foreground and background centers and the shape boundaries. Upon relative displacem ...
