  3. 2. Properties of Volume Bragg Gratings and Nonlinear Crystals for Laser Engineering

    Författare :Staffan Tjörnhammar; Fredrik Laurell; Valdas Pasiskevicius; Takunori Taira; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; volume Bragg grating; VBG; thermal effects; nonlinear optics; KTiOPO4; quasi-phase matching; photochromic damage; grey-tracking; color centers; blue-light induced infrared absorption; BLIIRA; Physics; Fysik;

    Sammanfattning : This thesis focuses on two topics: thermal limitations of volume Bragg gratings (VBGs) employed as laser-cavity mirrors and formation of color centers in KTiOPO4 and its isomorphs.To explore the mechanisms of the thermal limitations of VBGs in high power lasers, I designed and constructed a diode-pumped, solid‑state laser with a VBG as cavity mirror that had a significantly higher absorption than what is typical.

  4. 3. On Robotic Work-Space Sensing and Control

    Författare :Magnus Linderoth; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics; computer vision; color constancy; motion blur; filter initialization; visual tracking; on-line trajectory generation; ball-catching robot; force control; robotic assembly; force estimation; perception-action capabilities.;

    Sammanfattning : Industrial robots are fast and accurate when working with known objects at precise locations in well-structured manufacturing environments, as done in the classical automation setting. In one sense, limited use of sensors leaves robots blind and numb, unaware of what is happening in their surroundings. LÄS MER

  5. 4. Design and Implementation of Embedded Video Surveillance Hardware

    Författare :Fredrik Kristensen; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik och elektroteknik; Electronics and Electrical technology; image features; tracking; labeling; morphology; real-time operations; Hardware design; Image processing; Imaging; image processing; Bildbehandling; Signal processing; Signalbehandling;

    Sammanfattning : The demands on video surveillance systems are rapidly increasing regarding parameters such as frame rate and resolution. Furthermore, with an ever increasing number of video streams, an automated process for extracting relevant information is required. LÄS MER

  7. 5. Learning Convolution Operators for Visual Tracking

    Författare :Martin Danelljan; Michael Felsberg; Fahad Shahbaz Khan; Jiri Matas; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Visual tracking is one of the fundamental problems in computer vision. Its numerous applications include robotics, autonomous driving, augmented reality and 3D reconstruction. In essence, visual tracking can be described as the problem of estimating the trajectory of a target in a sequence of images. LÄS MER
