  1. 1. Comparison of Autofocus Methods for Highly Reflective Surfaces : A Case Study on the Inspection of Optical Filters

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Axel Hedvall; [2023]
    Nyckelord :autofocus; reflective surface; optical filter; visual inspection; autofokus; reflekterande yta; optiskt filter; visuell inspektion;

    Sammanfattning : Visual inspection is a crucial final step when manufacturing products, as it determines if a product can be sold or rejected. The inspection is often performed manually by trained inspectors, which is time-consuming and often subjective. By automating the inspection, it can be performed faster and more accurately. LÄS MER

  3. 2. Evaluation of Camera Resolution in Optical Flow Estimation Using Event-Based Cameras

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Simon Hellberg; Dominik Hollidt; [2020]
    Nyckelord :;

    Sammanfattning : Developments in event-based camera technology and their recent increase in pixel count raised the question of whether resolution helps the accuracy and performance of algorithms. This thesis studies the impact of resolution on optical flow estimation for event-based cameras. LÄS MER

  4. 3. Interpreting and composing SAGE II-III satellite data with a cloud algorithm for stratospheric aerosols

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Sammanfattning : Tolkning och kvantifiering av strålningseffekter pga. atmosfäriska partiklar är en signifikant del av IPCC’s modellering av hur tidigare klimat förändrats och hur förändringar i framtiden kommer se ut. LÄS MER

  5. 4. Methods for On-Chip Spectroscopy

    Master-uppsats, KTH/Mekatronik

    Författare :Magnus VALTERSSON; [2018]
    Nyckelord :algorithmic spectroscopy; optical filter; photodiode; internet of things; algoritmisk spektroskopi; optiskt filter; fotodiod; internet of things;

    Sammanfattning : Technology is rapidly becoming more compact and engineers are investigating new applications that are possible with this compact technology. For example photography has recently become an obvious part in our lives due to the shrinking of cameras. LÄS MER

  7. 5. Semi-filterless Optical Network : A Cost-efficient Passive Wide Area Network with Effective Resource Utilization

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Sahar Khanmohamadi; [2012]
    Nyckelord :;

    Sammanfattning : Two novel passive wide area network (WAN) approaches, filterless and semi-filterless optical networks, utilizing advanced optical coherent transmission and electrical compensation technologies are introduced. These approaches are able to eliminate or reduce the use of expensive active photonic reconfigurable components by interconnecting nodes with passive components. LÄS MER
