  1. 1. Design, Fabrication and Optimization of Thermal Radiation Detectors Based on Thin Polymer Membranes

    Författare :Claes Mattsson; Hans-Erik Nilsson; Göran Thungström; Ylva Bäcklund; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal detector; Polymer; Membrane; SU-8; Electronics; Elektronik;

    Sammanfattning : The number of applications in which infrared radiation sensors are used is increasing. In some applications, the cost of the sensor itself is an issue, and simple solutions are thus required. In this thesis, the investigations have related to the use of thin polymer membranes in thermal infrared sensors, such as bolometers and thermopiles. LÄS MER

  3. 2. Fabrication and Characterization of Photon Radiation Detectors

    Författare :Claes Mattsson; Hans-Erik Nilsson; Göran Thungström; Mikael Lindeberg; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Detectors; Posistion Sensitive Detectors; Electronics; Elektronik;

    Sammanfattning : This thesis involves a study the fabrication and characterization of photon radiation detectors. The focus has been to develop and improve the performance of optical measurement systems, but also to reduce their cost. The work is based on the study of two types of detectors, the position sensitive detector and the thermal detector. LÄS MER
