    Sammanfattning : Synchrotron and Free Electron Laser (FEL) light is becoming an increasingly sought after tool for almost all scientific research aspects. MAX IV Laboratory introduced the first 4th generation light source that provides the brightest synchrotron light in the world. LÄS MER

  3. 2. Target recognition by vibrometry with a coherent laser radar

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Andreas Olsson; [2003]
    Nyckelord :Reglerteknik; target recognition; vibrometry; coherent laser radar; laser vibration sensing; Doppler technique; time-frequency analysis; Reglerteknik;

    Sammanfattning : Laser vibration sensing can be used to classify military targets by its unique vibration signature. A coherent laser radar receives the target´s rapidly oscillating surface vibrations and by using proper demodulation and Doppler technique, stationary, radially moving and even accelerating targets can be taken care of.
