Maintaining polarization in optical fibers (PoF)

Apparatus and method for precisely maintaining the linear polarization of light at the output of an optical fiber

UHV-glass cell

The invention consists of a glass cell characterized by an outstanding value of birefringence (around 10–8) with an extensive optical access due to its dodecagonal shape.

odemS

Scientists of the Rheinische Friedrich Wilhelms University of Bonn and the Max Planck Gesellschaft developed a modular sensor system for online detection of Triacetontriperoxide (TATP) in gas phase. The detection took place in open air flow.

Adaptive Controller

Dynamic systems often use a two-position controller and a simple sensor that only indicates whether a threshold is exceeded or not.

Antireflective integrated optical waveguide

In transitions between dielectric optical waveguides of different thickness, it comes through modal mismatch usually to radiation losses and optical backscatter.

Plasmasensor

Plasmas are used in many technical fields. For instance, plasma assisted technologies are used to modify, clean or coat surfaces.

ComNoEL

Due to the steadily increasing number of electrical and electronic devices in motor vehicles, there is an ever-increasing disturbance on the supply lines. In particular the power electronics generate unwanted interference signals.

On-Board PSS Monitoring

The vehicle electrical system has become more and more complex over the years. Thus, the error probability increases, but an accurate fault identification and isolation becomes more and more difficult.

IConEVe

IConEVe is a decentralized control system for electrically operated vehicles.

VNA-Wheel Sensor

In today's passenger cars, a large number of sensors are installed which monitor the vehicle condition. For example, since 01.11.2014, all new cars have to be fitted with tire pressure sensors according to the EU regulation.

Open FET Sensor

The Open FET sensor is a field-effect-based sensor in which the gate electrode is connected only to the signal to be measured and not as usual to other electronic components.

WiMDaD Wire Mesh Damage Detection

Composite materials are nowadays used in many technical fields. Blades of wind power plants or aircraft parts, for example, are made out of these materials.

FoBT Sensor

Zugeschnitten auf die Anforderungen aus der Praxis wurde am Institut für angewandte Nano- und optische Technologien der Hochschule Niederrhein (iNano), Krefeld, der FoBt Sensor weiter entwickelt.

Vibration sensor

The vibration sensor works with two optical fiber sensors with Bragg gratings, in combination with a bending beam and a broadband light source.

Bose-Einstein-Light (BEL)

Lasers as sources for coherent and intense light are used in many high-tech applications and medical devices. Generally, the generation of Laser-light is characterized by a significant level of optical and electrical energy input and low efficiency.

On the trail of plasma

Plasmas are used in a wide range of technical applications, including semiconductor technology. Plasma etching and plasma-induced material deposition are used to remove functional layers in a structured manner or to selectively generate surface hardening, cleaning and activation on the target surface.

GridMaximizer

The electrical power grid is undergoing a major transformation. Increasing numbers of decentralized feeders have been added in recent years and, in the future, there will be a large number of charging stations for electric vehicles that temporarily draw a large amount of electrical power from the power grid.

Charge-Sensitive Amplifier

The charge-sensitive amplifier is an electronic circuit for amplifying the lowest voltages. It is suitable for the usual applications of an electrometer.
