Sławomir Tomczewski, PhD

Slawomir Tomczewski has obtained his PhD degree from Warsaw University of Technology. While doing his PhD, he also participated in three ACTPHAST projects, in which he cooperated with companies. Two of the projects were conducted with Kongsberg Automotive and one with Difrotec.

After finishing his PhD, he gained commercial experience while working at EDC Warsaw (General Electric Aviation) as a Software Engineer. Finally, before starting his current position, he worked as a Holographic System Engineer at Envisics LTD (Milton Keynes, UK).

Slawomir Tomczewski is currently developing flicker optoretinography, a method in which OCT is used to measure retina’s response to stimulation with periodic light pulses.

Flicker Optoretinography (f-ORG)

For many years visual inspection of fundus photography [1] and examination of images acquired with optical coherence tomography (OCT) [2] have been used by ophthalmologists for eye disease diagnosis and monitoring therapy progress thanks to their ability to detect morphological changes in the retina. However, imaging the morphological manifestation of retinal diseases alone does not provide sufficient […]

Two-Photon Excited-Fluorescence Scanning Laser Ophthalmoscope (TPEF-SLO)

The ability to noninvasively access metabolic processes during the visual cycle is crucial for developing therapies against retinal degenerative diseases. We have developed a protocol for obtaining in vivo two-photon excited fluorescence images of the fundus in the human eye. The visual cycle is a series of chemical transformations during which various fluorescent intermediates are […]
