  1. 16. Optical Analysis and Characterisation of the Climate Research Instrument STEAMR

    Författare :Arvid Hammar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; limb viewing; Monte Carlo; Stratosphere-Troposphere Exchange And climate Monitor Radiometer STEAMR ; quasi optics; THz; antennas; multi-beam; tolerance analysis; submillimeter-wave instruments; radiometers;

    Sammanfattning : A growing interest for making high resolution observations in the upper troposphere and lower stratosphere has motivated the development of the multi-beam satellite-borne instrument Stratosphere-Troposphere Exchange And climate Monitor Radiometer (STEAMR). The measurements made by STEAMR will be used to monitor trace-gases and link the occurence of these to the Earth's climate by accurate modeling of the atmosphere. LÄS MER

  2. 17. Optics for Earth Observation Instruments

    Författare :Arvid Hammar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; off-axis; free-form mirrors; measurements; stray light; spline horns; THz; reflector optics; satellites; scientific instruments; diamond turning; tolerancing; telescopes;

    Sammanfattning : The optical system is an essential part of every remote sensing instrument used for detecting electromagnetic waves. Careful design, fabrication and characterization is therefore crucial, especially for satellite-borne missions where the possibility of post-launch repairs is highly limited. LÄS MER
