About Robert J. Zawadzki

Robert J. Zawadzki

Robert J. Zawadzki (b.1975) received his MSc in Medical Physics from Nicholas Copernicus University (NCU), Torun, Poland under Prof. Andrzej Kowalczyk  supervision. He received his PhD in natural sciences from Technical University of Vienna, Vienna, Austria based on his work in the field of OCT at Medical Physics Institute, University of Vienna under Prof. Adolf F. Fercher supervision.

Presently he has a faculty position of assistant professional research in Dept. of Ophthalmology and Vision Science at University of California Davis, Sacramento, CA USA and works together with Prof. John S. Werner in his Vision Science and Advanced Retinal Imaging Laboratory. His research interest includes development and application of novel instrumentation for high resolution in-vivo retinal imaging. This includes Adaptive Optics (AO), Optical Coherence Tomography (OCT), Scanning Laser Ophthalmoscopy (SLO) and its combination.

    Explore Article SPIE Digital Library (Feb 19 2010)

    Evaluation of complex conjugate artifact removal methods used in spectrometer-based Fourier-domain optical coherence tomography systems - a comparative study We evaluated several, previously published, complex conjugate artifact removal methods and algorithms that have been proposed for Fourier domain optical coherence tomography (Fd-OCT). To ensure comparable conditions, only one OCT system was used, but with modified data acquisition schemes, depending on the requirements of each method/algorithm. This limited our evaluation to single spectrometer based Fd-OCT approaches. The suppression ratio of complex conjugate artifact images using a paperboard is assessed for ... (Read Full Article)

    Imaging the structure and correlating it with the biochemical content of the retina holds promise for fundamental research and for clinical applications. Optical coherence tomography (OCT) is commonly used to image the 3D structure of the retina and while the added functionality of biochemical analysis afforded by Raman scattering could provide critical molecular signatures for clinicians and researchers, there are many technical challenges to combine these imaging modalities. We describe ... (Read Full Article)
