  1. 11. Ground Based Attitude Determination Using a SWIR Star Tracker

    University essay from Linköpings universitet/Reglerteknik

    Author : Karl Gudmundson; [2019]
    Keywords : Star Tracking; Celestial Navigation; Navigation Systems; Attitude; Orientation; SWIR; MEKF;

    Abstract : This work investigates the possibility of obtaining attitude estimates by capturing images of stars using a SWIR camera. Today, many autonomous systems rely on the measurements from a GPS to obtain accurate position and attitude estimates. READ MORE

  3. 12. Dispersion management and characterization of ultrashort laser pulses for the optimization of parametric processes

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Axel Elfving; [2019]
    Keywords : frequency resolved optical gating; optical parametric amplification; difference frequency generation; nonlinear optics; laser pulse compression; lasers; optics; Technology and Engineering; Physics and Astronomy;

    Abstract : This thesis set out to continue the development of a short-wave infrared (SWIR) optical parametric amplifier (OPA). The system is based on a Yb-ber chirped pulse amplification (CPA) laser delivering 400 fs long pulses, centered around 1030 nm, at 200 kHz repetition rate and 40 W average power. READ MORE

  4. 13. Stand-alone Dual Sensing Single Pixel Camera in SWIR

    University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska fakulteten

    Author : Martin Oja; Sebastian Olsson; [2019]
    Keywords : Single Pixel Camera; SWIR; Compressive Sensing; Single Pixel Imaging; Image Reconstruction;

    Abstract : A Single pixel camera is just that, a camera that uses only a single pixel to take images. Though, it is a bit more to it than just a pixel. It requires several components which will be explained in the thesis. READ MORE

  5. 14. Noncollinear optical parametric amplification of a supercontinuum

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Henrik Åkesson; [2019]
    Keywords : optical parametric amplification; supercontinuum generation; nonlinear optics; laser pulse compression; lasers; optics; Physics and Astronomy; Technology and Engineering;

    Abstract : During this thesis, work has been done towards realizing a short-wave infrared (SWIR) laser source based on optical parametric amplification. It is planned that this setup should be able to produce few-cycle laser pulses at 2μm with a stable carrier-envelope phase (CEP). READ MORE

  6. 15. Assessing edge pixel classification and growing stock volume estimation in forest stands using a machine learning algorithm and Sentinel-2 data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Enzo Zerega; [2018]
    Keywords : Physical Geography; Ecosystem Analysis; Random Forest; remote sensing; accuracy assessment; land cover classification; training stage; multi-temporal; edge areas; Earth and Environmental Sciences; Science General;

    Abstract : Sustainable forest management requires accurate and up-to-date baseline data regarding forest structural parameters and the definition of forest stand units. A crucial component in stand characterization is the identification of tree species and to correctly define the stand boundaries. READ MORE
