Hybrid polymer microlens arrays with high numerical apertures fabricated using simple ink-jet printing technique

Jürgen Brugger, Edoardo Charbon, Vahid Fakhfouri, Dmitri Boiko, Joo Yeon Kim, Nils Benedict Brauer

Microlens arrays fabricated by a direct ink-jet printing of UV-curable hybrid polymer are reported. A periodic pattern of polymer drops was ink-jet printed on the surface-treated glass substrate and cured in the UV-light. Using this simple technique, we de ...

Controlling spectral response of photodetector for an image sensor

Edoardo Charbon, Cristiano Niclass

A method for controlling the spectral response of light sensitive semiconductor elements in an array (8) using an electric control signal (Vop) applied to said semiconductor elements. The light sensitive semiconductor elements could be a single photon aval ...

Using Digital Cameras as Quasi-Spectral Radiometers to Study Complex Fenestration Systems

Marilyne Andersen

This work discusses the use of digital cameras fitted with absorption filters as quasi-spectral radiometers. By filtering incident light into selected wavelength intervals, accurate estimates of radiances can be made for unknown spectra. This approach is b ...

Inkjet printing and high aspect ratio structuring for polymer-based micro and nano systems

Vahid Fakhfouri

Inkjet printing of functional materials, photolithography and micromolding are 3 different techniques largely used in the field of micro-electromechanical systems (MEMS) with increasing interest for the fabrication of new devices and the development of new ...

Process engineering and failure analysis of MEMS and MOEMS by Digital Holography Microscopy (DHM)

Mihai Adrian Ionescu, Christian Depeursinge, Etienne Cuche, Frédéric Montfort, Nicolas Aspert, Alexander Mehdaoui

Process engineering and failure analysis of MEMS and MOEMS require static and dynamical characterization of both their in-plane and out of plane response to an excitation. A remarkable characteristic of Digital Holography Microscopes (DHM) is the extremely ...

Improvement of the Contrast in Cancer Detection by Autofluorescence Bronchoscopy using a narrow spectral violet Excitation: A preliminary study

Hubert van den Bergh, Georges Wagnières, Tanja Gabrecht, Blaise Lovisa

Autofluorescence (AF) bronchoscopy is a useful tool for early cancer detection. However, the mechanisms involved in this diagnosis procedure are poorly understood. We present a clinical autofluorescence imaging study to assess the depth of the principal co ...

Stability and physical properties of alkylsilane and alkylphosphonate self-assembled monolayer (SAM) films on metal oxide substrates characterized at the micro- and nanoscale

Enamul Hoque

Self-assembled monolayer (SAM) films have attracted immense attention for both fundamental and applied research. A SAM is composed of a large number of molecules with a head group that chemisorbs onto a substrate, a tail group that interacts with the outer ...

Besoin en adhérence des revêtements de chaussées

André-Gilles Dumont

Ce travail porte sur les besoins en adhérence des chaussées. Ce phénomène met en jeu un grand nombre de paramètres liés à la fois à l’infrastructure (micro et macrotexture du revêtement de chaussée notamment), au véhicule et au conducteur. Ce travail se sc ...
