Retrofit polarization-maintaining in optical fibers (PM)

The invention of the University of Bonn relates to the development of a method to retrofit polarization- maintaining (PM) optical fibers in a way, that a routinated achievement of polarization to a degree better than 10-5 in extinction ratio takes place.

UHV-glass cell

The invention consists of a glass cell featuring an ultra-low birefringence (around 10–8) with an outstanding optical access due to its compact 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.

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.

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

Tailored to the current practical requirements, the FoBt Sensor has been developed by the Institute of Nanotechnologies and Optical Technologies (iNano) at the Niederrhein University of Applied Science.

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.

Substitute for LIDAR sensors

Optical components like photodiodes have a variety of uses in sensors and telecommunications technology. Even with time-of-flight sensors, the light reflected by objects has to be converted into electrical signals in order to compute the distance or speed of said objects.

Interference filter

Many optical systems, devices and sensors use the principle of interference - an essential factor in the development and optimization of thin-film devices.

Digital Power Factor Correction

By using this new digital power factor correction, the electromagnetic interference in power electronic systems such as battery chargers, plug-in power supplies, computer power supplies or e-bike chargers can be significantly reduced.

Microwave thermograph

The new method for microwave thermography uses a commercially available HD optical camera and an indicator plate to convert the microwaves into a high-resolution, digital field distribution. The developed indicator plate allows microwave thermography between 1 GHz and 300 GHz.

Measure the smallest of currents of CMOS chips

Lab-on a chip applications often need to be able to measure the smallest currents on CMOS chips. Thanks to a new measurement circuit, an offset and 1/f noise compensated current-to-digital conversion can be integrated directly on the chip and thus a current measurement can be realized cost-efficiently over a very large measurement range (fA - µA).

CMOS biosensors

Production process for a highly sensitive biosensor made from a crossed nanowire-structure field-effect transistor. The cost effective CMOS compatible production process allows for e.g. biosignal monitoring of molecules like c-reactive protein (CRP), cardiac troponin (cTnI), electrogenic cells, or peptides such as amyloid-beta.

Lock-In Amplifier

Lock-In amplifiers are firmly anchored in everyday research. They offer excellent noise suppression for repeating signals. The degree of suppression, however, depends critically on the low-pass filter at the end of the signal processing chain.

Window for high temperatures

For the monitoring of highly complex processes in closed reaction vessels, it would often be desirable to be able to observe the process and monitor it by means of optical measuring systems.

GAIPP

Isokinetic aerosol sampling is currently only designed and used in very narrow speed ranges. However, known diffusers are only permanently adjustable and designed for a specific flow velocity.

Synthetic Image Data

Almost all car manufacturers are currently developing camera-based autonomous or semi-autonomous vehicles.

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.
