LumiCS -
Terahertz illumination concepts for reciprocal
compressive imaging in silicon technologies

The project’s main objective is to leverage silicon-based technologies for a breakthrough in terahertz (THz) compressive imaging. This interdisciplinary research
project combines natural sciences with engineering sciences to realize a highly sensitive real-time THz imaging system without the need for mechanical scanning.
The key innovation of LumiCS is an active Terahertz Digital Light Processor (T-DLP) fully integrated in a silicon process technology.

for tumor related analytics: PCR-free
sensitivity, biomolecular extension and biological
relevance

Genomics and proteomics hold promise to revolutionize future health care, targeting profound novel visions like predictive, preventive and personalized medicine.
The enormous advance in these fields is closely coupled to the development of powerful, reliable and efficient methods to detect, identify and analyze biomolecules and their complex interaction networks. In the last decades techniques have continuously improved, providing a plethora of information for biomolecular function. Current progress is changing from “observing” dependencies, towards “understanding” mechanisms in their full interaction Network.

Simulation of Ultrasonic Wave Propagation Phenomena for the Optimal Design of Multi-Sensoric Monitoring Systems 

Maintenance costs have a big share of the total life cycle cost of a modern aircraft in addition to manufacturing and fuel cost.
In this context, structure-healthmonitoring systems (SHM-systems) have been integrated into aircrafts to detect early damage and to monitor efficiently the health of the structure.

Smart Intelligent Aircraft Structures -SARISTU


SARISTU (Smart Intelligent Aircraft Structures) is a large-scale integrated project which aims at achieving
reductions in aircraft weight and operational costs, as well as an improvement in the flight profile specific aerodynamic
performance. Coordinated by Airbus, the SARISTU Consortium brings together 64 partners from
16 European countries. The total budget of the project is 51 M€, partially funded by the European Commission
under FP7-AAT-2011-RTD-1 (Grant Agreement number 284562). The project started in September 2011 and is
expected to be completed by August 2015.

Interactive Analysis of Multi-modal Confocal
Raman Microscopy Data

The DFG-project “Interaktive multifunktionelle konfokale Bildanalyse” involves the analysis and visualization
of the measurement data obtained from our multispectral confocal Raman microscopy system.
Specifically, the motivation of the project is to detect constituting components and physical structure of the
specimen and present the results in a concise and intuitive manner.

Modelling and Optimizing the Ion-Exchange Process
for Manufacturing Optical Waveguides

Since more than 10 years, the research group led by Prof. Griese, has consistently investigated on the
potentiality of using optical multimode waveguides on printed circuit boards (PCBs). During these years
extensive experience in design, simulation, producing electrical-optical circuit boards (EOCBs) and optical
interconnections from different BMBF supported collaborative research projects has been gained.

HITCHHIKER -
Bistatic Synthetic Aperture Radar Imaging
with a Stationary Passive Receiver System

To develop efficient algorithms for bistatic SAR focussing, there is a need for test data sets. Therefore it was
decided to build up an own affordable sensor system to perform bistatic SAR experiments. Because of the high
operating cost of a moving sensor platform, a stationary receiver was considered.

Hitchhiker -
Multi Channel SAR Sensor

Continuing the microwave based bistatic imaging line, the Hitchhiker system is being upgraded to a fully operational
flexible multi waveform interferometric Synthetic Aperture Radar Imaging system. Designed in
2009, Hitchhiker was initially a purely passive bistatic receiver system working with TerraSAR-X microwave
illumination with two coherent channels, one channel for the direct signal of the transmitter and another one
for scene echoes.

Early invasive fungal infection detection with Terahertz sensor systems

Due to medical advances in fields of transplant technology and cancer therapy these procedures now come
on in daily clinical life. These interventions or therapies require the suppression of the patient’s immune
system. So the patient becomes susceptible to infections of any kind. At this point Invasive-Fungal-Infections
(IFI) are a serious health problem.

Two-dimensional materials - a new playing ground for engineers

Graphene is a two-dimensional (2D) crystal made up of carbon atoms arranged in a honeycomb lattice. It is
only one atomic layer thick, which makes it the thinnest material known to exist. Graphene also happens
to be the strongest material, an excellent conductor for both electric current and heat, highly transparent and
very flexible and stretchable.
