Mobile TV viewers can change the viewing distance and (on some devices) scale the picture to their preferred viewing ratio, trading off size for angular resolution. We investigated optimal trade-offs between size and resolution through a series of studies. ...
Large network monitoring of electrogenic cells by means of micro electrode arrays (MEA) has become a valuable methodology in electrophysiology. In order to understand the mechanisms of learning (plasticity) and memory in fundamental neuroscience it is impe ...
In this thesis new imaging approaches for optical microscopy are proposed and studied. They are based on the use of dynamic structured illumination in combination with a demodulation detection concept employing CMOS image detectors. Two particular implemen ...
This paper present a polarimetric fiber optics current sensor using a 22.5 degree Faraday rotator and a Faraday rotation mirror. The objective of this sensor is to be low-cost, high accuracy and easy to manufacture ...

We propose a microfabrication technology for a flexible temperature sensor with a 100x100 mu m(2) sensing area and a probe length of 7 cm. We use a biocompatible new high temperature-resistant polyimide (U-Vamish-S, Ube, Dosseldorf, Germany) to embed a thi ...

We present the first fully CMOS-integrated 3D Hall probe. The microsystem is developed for precise magnetic field measurements in the range from mT up to tens of tesla in the frequency range from DC to 30 kHz and with a spatial resolution of about 150 μm. ...
In the course of 1998, the Spectromicroscopy beamline at ELETTRA completed commissioning and succeeded in performing its first test experiments. The beamline is designed to perform photoemission experiments with high spatial resolution, which is obtained b ...
We developed a new integrated magnetic sensor based on the Hall effect, suitable for the application in magnetic contactless 360° absolute angle sensors. The device consists of a narrow n-well ring with a chain of 64 contacts equally distributed around the ...
In this paper, we discuss the fundamental limitations of the SBS analysis as a distributed sensing method when the spatial resolution is in the meter range. We also present a novel experimental configuration that reaches the best performances achievable fo ...
Optical low coherence reflectometry (OLCR) was used for the measurement of the local fiber Bragg grating (FBG) birefringence. The birefringence with resolution of 4 x 10(-6) was determined directly from oscillations in the OLCR amplitude with a spatial res ...
