    • Deep Optical Coding Design in Computational Imaging: A data-driven framework 

      Arguello, Henry; Bacca, Jorge; Kariyawasam, Hasindu; Vargas, Edwin; Marquez, Miguel; Hettiarachchi, Ramith; Garcia, Hans; Herath, Kithmini; Haputhanthri, Udith; Ahluwalia, Balpreet Singh; So, Peter; Wadduwage, Dushan N.; Edussooriya, Chamira U.S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-27)
      Computational optical imaging (COI) systems leverage optical coding elements (CEs) in their setups to encode a high-dimensional scene in a single or in multiple snapshots and decode it by using computational algorithms. The performance of COI systems highly depends on the design of its main components: the CE pattern and the computational method used to perform a given task. Conventional approaches ...

    • Improving the space-bandwidth product of structured illumination microscopy using a transillumination configuration 

      Joseph, Joby; Faiz, Kandankulangara P.; Lahrberg, Marcel; Tinguely, Jean-Claude; Ahluwalia, Balpreet Singh (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-18)
      Applying structured instead of plane illumination in widefield optical fluorescence microscopy can improve the spatial resolution beyond what is known as the Abbe limit. In general it is not only the resolution of an imaging system that is of interest but also its field of view (FOV). These two parameters are expressed in the space-bandwidth product (SBP). Here we introduce a modified structured ...

    • Mitochondrial dynamics and quantification of mitochondria-derived vesicles in cardiomyoblasts using structured illumination microscopy 

      Opstad, Ida S.; Godtliebsen, Gustav; Ahluwalia, Balpreet Singh; Myrmel, Truls; Agarwal, Krishna; Birgisdottir, Åsa Birna (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-12)
      Mitochondria are essential energy-providing organelles of particular importance in energy-demanding tissue such as the heart. The production of mitochondria-derived vesicles (MDVs) is a cellular mechanism by which cells ensure a healthy pool of mitochondria. These vesicles are small and fast-moving objects not easily captured by imaging. In this work, we have tested the ability of the optical ...

    • Nanoscopy on-a-chip: super-resolution imaging on the millimeter scale 

      Helle, Øystein Ivar; Coucheron, David Andre; Øie, Cristina Ionica; Ahluwalia, Balpreet Singh (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-04)
      Optical nanoscopy techniques can image intracellular structures with high specificity at sub-diffraction limited resolution, bridging the resolution gap between optical microscopy and electron microscopy. So far conventional nanoscopy lacks the ability to generate high throughput data, as the imaged region is small. Photonic chip-based nanoscopy has demonstrated the potential for imaging large areas, ...
