A micromachined earth sensor based on measuring the gravity gradient torque
We present the fabrication and testing of a novel MEMS inertial sensor that directly measures the gravity gradient in low Earth orbit in order to sense the relative orientation of a satellite with respect to the Earth. Instead of the current Earth sensing ...
American Soc Mechanical Engineers, Three Park Avenue, New York, Ny 10016-5990 Usa2009High Resolution Interference Microscopy: 3D measurement of focused light at 405nm applied to optical disc
Hans Peter Herzig, Toralf Scharf, Myun Sik Kim
High capacity data storage on DVD and optical discs is based on focused light beams. The characterization of light fields within the focus point is a very difficult task, which requires a high-resolution method like scanning near field optical microscopy ( ...
2009Quantum Yield Measurement of Fluorescent Zeolite Nanopigments
Libero Zuppiroli, Rolando Ferrini
Organic fluorescent molecules are infiltrated in the channels of zeolite L nanocrystals, thus creating organic-inorganic fluorescent nanoparticles. Combined with dielectric matrices, these fluorescent nanopigments open the way to the realization of novel o ...
Wiley-Blackwell2009Femtosecond Laser Microfabrication of an Integrated Device for Optical Release and Sensing of Bioactive Compounds
Flash photolysis of caged compounds is one of the most powerful approaches to investigate the dynamic response of living cells. Monolithically integrated devices suitable for optical uncaging are in great demand since they greatly simplify the experiments ...
2008A Micro-Electrode Array device coupled to a laser-based system for the local stimulation of neurons by optical release of glutamate
Optical stimulation is a promising approach to investigate the local dynamic responses of cultured neurons. In particular, flash photolysis of caged compounds offers the advantage of allowing the rapid change of concentration of either extracellular or int ...
Elsevier2008Optical apparatus for dual beam heterodyne Fourier domain optical coherence tomography, has detector that synchronizes phase shift such that sample signal or sample interface moving at arbitrary velocity is detected by phase change
Theo Lasser, Rainer Leitgeb, Martin Villiger, Adrian Bachmann, Roland Michaely
NOVELTY - The apparatus has an optical unit for splitting a source field to produce and combine reference and biomedical sample light fields. An optical and electronic unit records a spectral interference pattern between combined light fields. A controlled ...
2008An exploratory search for z greater than or similar to 6 quasars in the ukidss early data release
Frédéric Courbin, Georges Meylan, Alexander Patrick Eigenbrod
We conducted an exploratory search for quasars at z similar to 6-8, using the Early Data Release (EDR) from the United Kingdom Infrared Deep Sky Survey (UKIDSS) cross-matched to panoramic optical imagery. High-redshift quasar candidates are chosen using mu ...
2008Scalable Asynchronous Incoherent Optical CDMA [invited]
We present and review several aspects of incoherent optical code-division multiple access (OCDMA), focusing on the flexible bandwidth allocation and its potential for future optical networks. We briefly present the various OCDMA approaches, coherent and in ...
2007Electroactive nanowells for spectrographic fluidic memory
Current optical storage devices such as DVDs have their read/write capabilities fundamentally restricted by the diffraction limit of light. We present an optofluidic architecture for storing cocktails of colloidal quantum dots in electroactive nanowell str ...
2007Scale-space analysis and active contours for omnidirectional images
Jean-Philippe Thiran, Pierre Vandergheynst, Xavier Bresson, Iva Bogdanova Vandergheynst
A new generation of optical devices that generate images covering a larger part of the field of view than conventional cameras, namely catadioptric cameras, is slowly emerging. These omnidirectional images will most probably deeply impact computer vision i ...
