    Sammanfattning : Camera modelling and calibration are important parts of machine vision. They can be used for calculating geometric information from images. A camera model is a mathematical projection between a 3D object space and a 2D image. LÄS MER

  4. 3. Design, Characterization, and Calibration of Low-Noise Terahertz Receivers

    Författare :Olle Nyström; Chalmers University of Technology; []
    Nyckelord :receiver characterization; instrumentation; antenna design; Radio astronomy; calibration; optics;

    Sammanfattning : This thesis is focused on the field of instrumentation for radio-astronomy and atmospheric science, and specifically deals with problems such as optical design and its verification, horn antennas and receiver optics’ components, different aspects of measurement systems in order to characterize low-noise THz receivers, and its calibration techniques.Ultra low-noise Terahertz receivers, used in radio-astronomy, are typically coupled to the telescope system through relay optics that provides guiding of the signal to the receiver frontend with minimal loss.
