OSA Biophotonics Congress 2019


Professor M. Wojtkowski and his team participated in the conference Biophotonics Congress: Optics in the Life Sciences, organized by the Optical Society of America. This event provided researchers  with the opportunity to discuss the design, fabrication, and application of biomedical optical technologies for life sciences.

The main goal of Professor M. Wojtkowski's visit was participation as the Program Committee Member in the session: “Bio-Optics: Design and Application (BODA)”. He chaired the session “DT2B • Optical Imaging Technologies II ”. The team also delivered two talks:

  • “Speckle-free and cross-talk-free imaging in Fourier domain fullfield optical coherence tomography” (Patrycjusz Stremplewski, Egidijus Auksorius, Pawel Wnuk, Lukasz Kozon, Piotr Garstecki, Maciej Wojtkowski), presented by Egidijus Auksorius. He reported on a system that is able to significantly reduce cross-talk and speckle noise in Fourier domain full-field optical coherence tomography. It is achieved by fast phase modulation of a laser wave front and angular compounding.
  • “Speckle decorrelation for cell’s dynamics” (Paulina Niedzwiedziuk, Maciej Wojtkowski, Karol Karnowski), presented by Paulina Niedzwiedziuk. She reported on lung cancer cells were measured in scanning Optical Coherence Microscopy setup. Consecutive 2D speckled data was decorrelated to obtain flow information. They observed regions that are more active than others.

Apart from the above, the CREATE team also presented posters:

  • “Application of single-pixel camera for imaging in turbid media” (Julia I. Sudyka, Michal Hamkalo, Maciej Wojtkowski) presented by Julia I. Sudyka. She presented an imaging technique based on the single-pixel camera concept. The method encompasses two dimensional image acquisition with possible data compression and only a singular photodiode needed. Their system may become an important tool for modern microscopy.
  • “Optofluidic Platform for Bacteria Screening in Nanoliter Droplets” (Jakub Boguslawski , Natalia Pacocha , Michal Horka ,Maciej Wojtkowski, Piotr Garstecki) presented by Jakub Boguslawski. A microfluidic platform for an optical, label-free screening of bacteria growth in nanoliter droplets was demonstrated. Jakub showed that based on droplet’s scattering properties we can perform a reliable binary readout.
