The Sensors Group focuses on the development of sensor systems for active, optical remote sensing techniques for the generation of maritime situation pictures. The group’s activities are divided into three areas:
In the TRAGVIS project an active optical sensor in the near-infrared is being developed. The pulsed light source is synchronised with a camera, so that in the recorded image distance-dependent illumination is achieved. This causes a reduction of atmospheric backscatter signals, resulting in improved image contrast (range-gating). The application focuses in particular on marine rescue under poor visibility conditions (night and fog)
Simulations of environmental conditions and instruments are conducted to understand and investigate the measurement methods, as well as to further develop the instruments. In addition, a platform will be installed at the institute’s rooftop from where developed sensors can be operated in long-term tests under variable conditions in the maritime environment (open-air laboratory), and subsequently compared with the results of the simulations. Prevailing environmental conditions are recorded by complementary instruments (e.g. weather station, radiometer, and aerosol spectrometer).
