  1. 21. Geometric Models for Rolling-shutter and Push-broom Sensors

    Författare :Erik Ringaby; Per-Erik Forssén; Tomáŝ Pajdla; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Almost all cell-phones and camcorders sold today are equipped with a  CMOS (Complementary Metal Oxide Semiconductor) image sensor and there is also a general trend to incorporate CMOS sensors in other types of cameras. The CMOS sensor has many advantages over the more conventional CCD (Charge-Coupled Device) sensor such as lower power consumption, cheaper manufacturing and the potential for onchip processing.

  5. 24. Fabrication and characterization of ZnO nanostructures for sensing and photonic device applications

    Författare :Syed M. Usman Ali; Magnus Willander; Omer Nour; Frank Bier; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanotechnology; zinc oxide; nanowires nanorods; nanotubes; nanoporous nanoflakes; electrochemical sensor and photonic devices;

    Sammanfattning : Nanotechnology is an emerging inter-disciplinary paradigm which encompasses diverse fields of science and engineering converge at the nanoscale. This nanoscale science and nanostructure engineering have well demonstrated in the fabrication of sensors/transducers devices with faster response time and better sensitivity then the planer version of the sensor’s configurations.
