AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
We present a microspectrometer based on a tunable interference filter for infrared or visible light that scans the desired part of the spectrum within milliseconds. A single pixel detector measures serially the intensity at selected wavelengths. This conce ...
This work deals with the concept of active materials with variable acoustic properties, dedicated to room acoustics applications. This concept is based on an acoustic impedance active control principle by hybrid motionnal feedback, applied on an electroaco ...
We present a tunable interference filter for infrared and visible light that scans the desired part of the optical spectrum within milliseconds. A single pixel detector measures serially the intensity at selected wavelengths. This concept: avoids expensive ...
We report state resolved sticking coefficients for highly vibrationally excited CH4 on Ni(100) at well-defined kinetic energies in the range of 12-72 kJ/mol. Incident methane molecules are prepared by pulsed laser radiation in single rovibrational levels o ...

The 90-degrees geometry - with reference and signal beams entering orthogonal crystal faces - is used to angularly multiplex up to 500 holograms at each of 8 spatially multiplexed locations in a LiNbO3 crystal. A segmented mirror array and a 2D mechanical ...
The low energy part of proton induced SBD spectra have higher number of counts than expected from p+Si reactions. This is the case for all proton incident angles but the effect increases when approaching grazing angles. The effect is shown to be mainly due ...
