Dr. Werner Ritter
Dr. Werner Ritter received his M.Sc. in Computer Science from the Technical University of Berlin in 1988 and his PhD from the University of Koblenz in 1996. His thesis dealt with a traffic sign recognition system in color image sequences, which was successfully demonstrated during the final review of the European PROMETHEUS project in 1994. Until 2000 he led the development of the DAIMLER traffic sign recognition system at DAIMLER´s research. From 2000 - 2012, he was responsible for the development of the DAIMLER nigh view system in the DAIMLER research department. Since 2012 he has been responsible for the development of DAIMLER´s bad-weather-driver-assistance systems. With this focus, he manages the DAIMLER activities of several publicly funded EU projects. He is currently coordinating the publicly funded EU ECSEL project DENSE (aDverse wEather eNvironmental Sensing systEm, 2016 - 2019) with the goal of developing a 24/7 all-weather sensor suite.
What happens to self-driving cars if the weather turns bad? New Sensor Suite for driver assistance and automated driving working 24/7 – in all weather
Current Advanced-Driver-Assistance-Systems (ADAS) offer comfort and safety in good weather. However, they often fail to sense their surroundings in visibility conditions with heavy rain, snow or fog causing the automated systems to stop their support.
The publicly funded EU project DENSE (aDverse wEather eNvironmental Sensing systEm, www.dense247.eu) addresses this key challenge of autonomous driving by developing a fully reliable environment perception technology that extends the performance of sensors in adverse visibility conditions. The project designs, tests and validates a generic and affordable sensor suite that enables driver assistance systems and autonomous driving systems to operate also in adverse weather.
The project started in June 2016. After a short overview of the currently used sensors and their limitations in adverse weather, results of the sensor development and testing, as well as of the processing unit are presented.

When precision matters: Femtosecond lasers, Terahertz systems, and optical frequency combs, and its applications
Menlo Systems GmbH is a leading developer and global supplier ofinstrumentation for high precision metrology. The presentation will summarize latest technology achievements in its Nobel Prize winning optical frequency comb products and highlight some recentapplications that are enabled by the high precision instrumentsbased on femtosecond lasers, Terahertz systems, and optical frequency combs.
Dr. Christian Waltermann
Christian Waltermann was born in 1986, studied physics at the Leibnitz University Hanover at the Institute for Quantum Optics until 2012 and doctorated at the Fraunhofer Heinrich Hertz Institute on a new kind of fiber optical 3D shape sensor afterwards in 2016. For over ten years, he has been working on the modification of different materials with femtosecond laser pulses and the creation of FBG-based sensors. He founded FiSens in 2017, formerly FiberSense, together with Philip Guehlke.
Highly focused femtosecond laserpulses are applied to create a unique diffractive element directly within the core of a standard optical fiber. Without the need of any pre- or postprocessing the nanoscopic grating combines all optical components of a classical spectrometer and leads to a device with sub-nanometer resolution even at extremely small footprints. The only two remaining components are the modified optical fiber and a detector which allows economic and robust spectroscopy even at industrial scale. As a first application a miniaturized interrogation system for fiber optical sensors is presented.
