  2. 1. Biological Inspired Deformable Image Sensor

    Author : Wei Wen; Khatibi Siamak; Coleman Sonya; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; image sensor; pixel form; sub-arrangements; fill factor; square image; hexagonal image; deformable sensor; quality assessment.;

    Abstract : Nowadays, cameras are everywhere thanks to the tremendous progress on sensor technology. However, their performance is far away from what we experience by our eyes. READ MORE

  4. 2. Optical Imaging for Nanowire Mechanics

    Author : Monica Lexholm; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sensor applications; optical imaging; nanowire mechanics; Fysicumarkivet A:2010:Lexholm;

    Abstract : In this work, we present a stroboscopic detection technique for the study of oscillating nanoscale objects. This optical read-out gives a position accuracy better than 1 nm which is a fraction of both the diffraction limit and the pixel size. READ MORE

  5. 3. Development and use of an optical pCO2 sensor in marine studies

    Author : Dariia Atamanchuk; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pCO2; O2; sensor; optode; cross-sensitivity; carbonate system of seawater; biogeochemistry; Redfield ratio; the Koljo Fjord; cabled observatory; CCS; QICS; environmental engineering; leakage detection; MVDA; DoE;

    Abstract : Partial pressure of CO2 (pCO2) is one of the most important parameters, which are measured in the global ocean in conjunction with ocean acidification studies. It is also a parameter of great interest to aquaculture and fish industries since CO2 in large amounts is highly toxic for animals. The requirements for pCO2 measuring systems, e.g. READ MORE

  6. 4. Characterization of an Electrical Sensor for Combustion Diagnostics

    Author : Axel Franke; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ion sensor; combustion; nitric oxide; chemi-ionization; equilibrium; Physics; ionized gases; Fysicumarkivet A:2002:Franke; ionization sensor; Fysik;

    Abstract : The ionization sensor is an electrical probe for diagnostics in internal combustion engines. The combustion process affects the electrical properties of the gas in the cylinder. Thus the sensor signal contains copious information about the conditions in the combustion chamber. READ MORE

  7. 5. Silicon Carbide High Temperature Photodetectors and Image Sensor

    Author : Shuoben Hou; Mikael Östling; Carl-Mikael Zetterling; Per-Erik Hellström; Anthony O'Neill; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon Carbide SiC ; high temperature; photodetector; photodiode; phototransistor; ultraviolet UV ; transistor-transistor logic TTL ; bipolar junction transistor BJT ; integrated circuit IC ; pixel sensor; image sensor; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Silicon Carbide (SiC) has the advantages of ultraviolet (UV) sensing and high temperature characteristics because of its wide band gap. Both merits make SiC photodetectors very attractive in astronomy, oil drilling, combustion detection, biology and medical applications. READ MORE
