  1. 1. Real-time Autofocus Algorithm in Laser Speckle Contrast Imaging

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Giovanni Russo; [2023]
    Keywords : Laser speckle contrast imaging; Autofocus; Blind image sharpness assessment; Speckle noise; Perimed’s Perfusion Speckle Imager;

    Abstract : Microcirculation is defined as the blood flow in the smallest blood vessels. Laser speckle contrast imaging (LSCI) is a full field imaging technique that provides instantaneous 2-D perfusion maps of illuminated tissues based on speckle contrast. READ MORE

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

    University essay from KTH/Skolan för industriell teknik och management (ITM)

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

    Abstract : 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.

    Abstract : The use of piezoelectric crystals as a way to achieve automatic alignment of an image sensor in a camera was investigated in collaboration with Axis Communications AB. Piezoelectric crystals can be created into different configurations, piezoelectric stacks being one of the simpler ones. READ MORE

  5. 4. Auto focus for electrons

    University essay from Lunds universitet/Synkrotronljusfysik

    Author : Majd Salman; [2011]
    Keywords : Physics and Astronomy;

    Abstract : Autofokus för elektroner Människan har alltid varit intresserad av att studera förlopp som skett så snabbt att de inte gått att observera med blotta ögat. Med hjälp av kameror med korta slutartider kan man frysa ett ögonblick i tiden. Processer i atomer och molekyler sker på en helt annan tidsskala än den vi är vana att fotografera. READ MORE
