  1. 1. Natural Fingerprinting of Steel

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Johannes Strömbom; [2021]
    Keywords : fingerprinting; laser speckles; speckle correlation; scattering transform; wavelets; feature detection;

    Abstract : A cornerstone in the industry's ongoing digital revolution, which is sometimes referred to as Industry 4.0, is the ability to trace products not only within the own production line but also throughout the remaining lifetime of the products. READ MORE

  3. 2. Simulated Laser Triangulation with Focus on Subsurface Scattering

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Author : Hilma Kihl; Simon Källberg; [2021]
    Keywords : Laser triangulation; subsurface scattering; simulation; speckle pattern; Gaussian beam; Blender; spruce wood; blister package;

    Abstract : Practical laser triangulation sessions were performed for each measurement object to obtain ground truth data. Three methods for laser line simulations were implemented: reshaping the built-in light sources of Blender, creating a texture projector and approximating a Gaussian beam as a light emitting volume.

  4. 3. Gasket Quality Control

    University essay from Lunds universitet/Industriell Produktion

    Author : Chinthan Rai; Shashank Bhanuprakash; [2021]
    Keywords : Quality-control; Gasketed plate heat exchangers GPHE ; Cross-section measurement; Laser line triangulation LLT ; Blue laser; Handheld 3D scanning; MCDM; AHP.; Technology and Engineering;

    Abstract : The heat exchanger is a system where heat gets transferred between oil and other forms of lubricants from one system to another without mixing through conduction. The hot liquid is cooled by passing through the heat exchangers plates, which act as a wall between them. READ MORE

  5. 4. Laser line extraction with sub-pixel accuracy for 3D measurements

    University essay from Linköpings universitet/Beräkningsmatematik; Linköpings universitet/Tekniska fakulteten

    Author : Mirjam Mattsson; [2020]
    Keywords : laser line extraction; Steger’s method; Gaussian fitting; Centre of Mass;

    Abstract : One 3D measurement method is laser scanning. By projecting and photographing a laser line, the centre line coordinates of the laser can be obtained with centre line detection methods and then be used to generate 3D model of the scanned object. READ MORE

  6. 5. Generation and Characterization of Intense Attosecond Pulses

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

    Author : Marius Plach; [2020]
    Keywords : Attosecond physics; high-order harmonic generation; high harmonic generation; HHG; attosecond pulses; molecular dynamics; attosecond pulse generation; harmonic emission time delay; temporal reconstruction of attosecond pulses; strong field processes; Three-step model; RABBIT; Reconstruction of Attosecond Beating By Interference of Two-photon Transition; Terawatt Laser System; Intense XUV Beamline; XUV; LLC; Physics and Astronomy;

    Abstract : Research on ultrafast dynamics in atoms and molecules requires short pulses. In order to resolve processes taking place on a femtosecond timescale sufficiently, these pulses require a duration on the attosecond time scale. READ MORE
