  1. 1. Alignment of Image Sensor using Piezoelectric Crystals

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Julia Jakobsson; Reem Chahrour Muhieddine; [2023]
    Keywords : piezo; piezoelectric; crystal; piezoelectric crystal; piezoelektrisk; kristall; piezoelektrisk kristall; camera; kamera; focus; fokus; Axis; Axis Communications; alignment; justering; prototyp; prototype; algorithm; algoritm; Technology and Engineering;

    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

  3. 2. Probing for plumes in observations of Europa in transit over Jupiter : A data analysis using Hubble Space Telescope images

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Emil Larsson; [2022]
    Keywords : Europa; Jupiter; Hubble Space Telescope; Water; Plumes; Europa; Jupiter; Hubbleteleskopet; Vatten; Plymer;

    Abstract : In 2016 Sparks et al. [14] reported evidence of water plumes above the Galilean moon Europa. Their method consisted of creating a model image of Europa transiting Jupiter and analytically comparing it with an actual far-ultraviolet observation from the Hubble Space Telescope. In 2020 Giono et al. READ MORE

  4. 3. Real-time Ray Traced Ambient Occlusion and Animation : Image quality and performance of hardware- accelerated ray traced ambient occlusion

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Fabian Waldner; [2021]
    Keywords : Ambient occlusion; ray tracing; real-time; animation; Ambient ocklusion; strålspårning; realtid; animation;

    Abstract : Recently, new hardware capabilities in GPUs has opened the possibility of ray tracing in real-time at interactive framerates. These new capabilities can be used for a range of ray tracing techniques - the focus of this thesis is on ray traced ambient occlusion (RTAO). READ MORE

  5. 4. Hardware-Accelerated Ray Tracing of Implicit Surfaces : A study of real-time editing and rendering of implicit surfaces

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Herman Hansson Söderlund; [2021]
    Keywords : Implicit Surfaces; Signed Distance Functions; Ray Tracing; Content Creation; Path Tracing; Implicita Ytor; Signed Distance Functions; Strålspårning; Modellering;

    Abstract : Background. Rasterization of triangle geometry has been the dominating rendering technique in the real-time rendering industry for many years. However, triangles are not always easy to work with for content creators. READ MORE

  6. 5. Iterative Reconstruction Algorithm for Phase-Contrast X-Ray Imaging

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Ahmad Sadek; Ruben Pozzi; [2020]
    Keywords : Computed tomography; Medical research; Phase-contrast imaging; Propagation-based imaging; SIRT; Iterative algorithm; Paganin’s phase-retrieval; Datortomografi; Medicinsk forskning; Faskontrastavbildning; Propagation-baserad avbildning; SIRT; Iterativ algoritm; Paganins fasåterhämtning;

    Abstract : Phase-contrast imaging (PCI) is a modality of medical x-ray imaging that can solve one of the main limitations with conventional attenuation-based imaging: the imaging of materials with low attenuation coefficients, such as soft tissues. A modality of PCI, Propagation-based phase-contrast imaging (PBI), was used in this project. READ MORE
