Analyzing Volleyball Match Data from the 2014 World Championships Using Machine Learning Techniques

Pascal Fua, Horesh Beny Ben Shitrit

This paper proposes a relational learning based approach for discovering strategies in volleyball matches based on optical tracking data. In contrast to most existing methods, our approach permits discovering patterns that account for both spatial (that is ...

Optical microscopy using a glass microsphere for metrology of sub-wavelength nanostructures

Martinus Gijs, Hui Yang

A technique that allows direct optical imaging of nanostructures and determines quantitatively geometric nanofeatures beyond the classical diffraction limit by using high-refractive index glass microspheres is introduced. The glass microsphere is put on a ...

Wide-band slow light in compact photonic crystal coupled-cavity waveguides

Vincenzo Savona, Momchil Minkov

Slow light has a variety of applications, in particular for enhanced nonlinear effects like four-wave mixing and high-harmonic generation. Here, we propose a photonic crystal coupled-cavity waveguide with an ultracompact arrangement of the constituent cavi ...

Intensity and phase fields behind Phase Shifting Masks studied with High Resolution Interference Microscopy

Hans Peter Herzig, Toralf Scharf, Krishnaparvathy Puthankovilakam

The proximity printing industry is in real need of high resolution results and it can be done using Phase Shift Mask (PSM) or by applying Optical Proximity Correction (OPC). In our research we are trying to find out details of how light fields behind the s ...

Optical microscopy for biology and life sciences

Theo Lasser, Marcel Leutenegger

Optical microscopy has become a major non- or minimally invasive tool for investigating living organisms such as cells, tissues or small animals. Being such an essential tool for research and because lacking knowledge and insight in the working principles ...

Polarization-multiplexed encoding at nanometer scales

Carlos Alberto Macias Romero

Optical data storage was developed using binary encoding primarily due to signal to noise ratio considerations. We report on a multiplexing method that allows a seven fold storage increase, per storage layer, per side, and propose one that can yield theore ...

This paper describes the fabrication of functional optical devices by sectioning quantum-dot-in-nanowires systems with predefined lengths and orientations. This fabrication process requires only two steps, embedding the nanowires in epoxy and using an ultr ...

Amer Chemical Soc2014

Holographic optical tweezers (HOTs) extend optical trapping into three dimensions. Volume imaging then becomes a concern as trapped objects are easily moved out of focus of the imaging objective lens. Here we demonstrate a three-dimensional real-time inter ...

Optical Soc Amer2014

Life sciences have a constantly growing need for novel methodological approaches suitable to investigate the intracellular environment with increased temporal and spatial resolutions. Recently, optical near-field probes, such as laser-irradiated pointed me ...
