  1. 21. Circular Modulation Formats and Carrier Phase Estimation for Coherent Optical Systems

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Sebastian Joel Ortega Zafra; [2014]
    Keywords : ;

    Abstract : Digital coherent receivers stand today as a promising technology for the next generation of high-capacity optical systems. Coherent systems enable the use of multilevel modulation formats which increase the spectral efficiency of a system. READ MORE

  3. 22. Stabilization of an optical frequency comb to an external cavity

    University essay from Umeå universitet/Institutionen för fysik

    Author : Olof Rydberg; [2014]
    Keywords : ;

    Abstract : The subject of this master's thesis is stabilizing a frequency comb laser to an external cavity using a couple of servo controllers. The aim of the project was to build a pair of servo controllers, replacing parts of the existing commercial and proprietary solution already in use. READ MORE

  4. 23. Thermometry using OH laser-induced fluorescence excitation spectra: A feasibility study

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Matematisk fysik

    Author : Elin Malmqvist; [2013]
    Keywords : laser-induced fluorescence; LIF; temperature; temperature measurements; OH; Physics and Astronomy;

    Abstract : In this thesis, rotational spectra, acquired through laser-induced fluorescence (LIF) on the OH-radical, were used to evaluate temperatures in different combustion environments. By comparing experimental spectra with theoretical ones of known temperature, the temperature can be determined. READ MORE

  5. 24. Investigations of stereo setup for Kinect

    University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Author : Ekaterina Manuylova; [2012]
    Keywords : Kinect exploration; 3D reconstruction from stereo pair of Kinects using OpenCV; 3D reconstruction from one Kinect using Matlab; Kinect calibration;

    Abstract : The main purpose of this work is to investigate the behavior of the recently released by Microsoft company the Kinect sensor, which contains the properties that go beyond ordinary cameras. Normally, in order to create a 3D reconstruction of the scene two cameras are required. READ MORE

  6. 25. Underwater 3D Surface Scanning using Structured Light

    University essay from Centrum för bildanalys

    Author : Nils Törnblom; [2010]
    Keywords : 3D scanner; structured light; point cloud; underwater; nuclear reactor; image analysis; nondestructive testing; NDE; nondestructive examination; NDE;

    Abstract : In this thesis project, an underwater 3D scanner based on structured light has been constructed and developed. Two other scanners, based on stereoscopy and a line-swept laser, were also tested. The target application is to examine objects inside the water filled reactor vessel of nuclear power plants.
