Video endoscopy systems give physicians the ability to inspect internal structures of the human body by using a camera with attached endoscope optics. This technology has become a routine in clinics all over the world. Moreover, video endoscopy systems recently performed a technological change from PAL/NTSC image resolution to HDTV. There is a vast of literature on in-vivo and in-vitro experiments...
This paper presents an airborne multi-spectral imaging sensor which is able to simultaneously capture three visible and three near infrared channels. The first prototype was integrated in a Schiebel CAMCOPTER® S-100 VTOL (Vertical Take-Off and Landing) UAV (Unmanned Aerial Vehicle) for inflight tests. A low cost version of the initial multi-spectral imaging system was developed to fit into a more...
Multi-spectral video endoscopy provides considerable potential for early stage cancer detection. Previous multi-spectral image acquisition systems were of limited use for endoscopy due to (i) the necessary spatial scanning of push-broom approaches or (ii) the impractical long switching times of liquid crystal tunable filters. Recent technological advances in the field of tuneable filters, in particular...
Terahertz time-domain spectroscopy can be used to characterize silicon solar cell properties such as: conductivity, charge carrier mobility and density. Moreover, THz spectroscopy and imaging can be used for defect analysis in semiconductor and photovoltaic materials. This paper describes the investigation of optically injected charge carrier dynamics by the use of THz spectroscopy. THz-pump/THz-probe...
Accurate and up-to-date soil monitoring allow farmers to take rapid, targeted action in case of nutrient deficiencies and pest infestation. This is essential for the maximization of crop-yields. This paper describes an airborne multi-spectral imaging system which is able to simultaneously capture three visible and two near infrared channels. The system was integrated in a Schiebel CAMCOPTER®...
Modern video endoscopy systems give physicians the ability to inspect internal structures of the human body by using a camera with attached endoscope optics. Video endoscopy has become routine in clinics all over the world. Moreover, video endoscopy systems recently performed a technological change from PAL/NTS C image resolution to HDTV. There is a vast amount of literature on in-vivo and in-vitro...
