Diffractive Optics in Coherent Automotive LightingRecent developments in lighting technologies in the automotive industry is heading towards coherent light sources, as incoherent light is difficult to shape. A lot of work has been done to integrate laser-based light sources for headlamps, butlaser based backlighting is still under investigation. Using the laser as a light source and diffractive optical elements (DOEs), high-resolution and thin rear lights can be realized.Led by: B. Roth, M.

Imaging in Scattering MediaDue to the effects of strong scattering, imaging in complex media such as biological tissue remains one of the great challenges of modern optics. Recent studies have shown that these effects may be compensated by spatially manipulating the light´s wavefront with active optical devices. This project aims to apply wavefront-shaping techniques to established imaging methods to enhance imaging performance and penetration depth in strongly scattering samples.Led by: M. Rahlves, B.

AMIRA - Analysis of microbial relations in vivo using Raman microscopyProjekt AMIRA is a cooperation between HOT and the department for Hydrobiology and Environmental Biotechnology at the Institute for Sanitary Engineering and Waste Management (ISAH) of the LUH and intends to establish cytochrome c-resonant Raman microscopy (CRRM) for the continuous analysis of bacterial relations in native, undisturbed biofilms in vivo and in situ with a resolution at cell level. This will allow for the time the direct observation of ongoing biofilm formation including phylogenetic information and phenotypic adaptation in complex biofilms in vivo.Led by: A.-K.

PlanOS-SFB Sub-Project C05Subproject C05 is investigating polymer-based sensors for life science. These sensors enable the optical and spectroscopic analytics in fluidic systems. The aim is to design a sensor, which is able to detect lowest analytic concentrations (final target single-molecule sensitivity). Operating principle of the sensor are Whispering gallery resonances in microspheres.Led by: M. Wollweber, U. MorgnerYear: 2013Funding: DFG

PlanOS-SFB Teilprojekt C02The subproject C02 explores novel polymer-based sensor structures for optical strain-measurement, in terms of different sensor types as well as in terms of different manufacturing processes. In the long run, all approaches aim at a large-scale and a low-cost manufacturing process (e.g., roll-to-roll). The goal is the integration of sensor systems on polymer foils, which convert strain amplitude and direction into optical signals, enabling a wide range of applications. The main challenge lays in the implementation of strain sensors, which are based on intensity- and spectral-modulation, the study of parasitic effects and the development of calibration concepts as well as advancing lab-typical production processes to large-scale processes.Led by: B. RothYear: 2013Funding: DFG

PlanOS-SFB Sub-Project B04Aim of this project is the design and fabrication of micro-optical structures for guiding light inside thin polymer foils as well as coupling light into and out of the foil. To realize a large area sensor network within PlanOS, a perfect interaction between all optical devices such as light sources, sensors and detectors is of great importance. Therefore, micro-optical structures are necessary, which connect all components to the sensor foil. One of the key issues is to increase the coupling efficiency of these linking structures as much as possible to gain maximum performance of the sensor networks.Led by: M.
