Prof Marinko Sarunic visits the AOG

On Thursday 21st of March, the AOG was visited by a distinguished guest, Prof Marinko Sarunic, who is a Professor and Associate Director in the School of Engineering Science at Simon Fraser University in Burnaby (Greater Vancouver), BC, Canada. Prof Sarunic has published over 80 journal articles on topics related to Optical Coherence Tomography, spanning image acquisition, image processing, and applications. He is currently an Associate Editor for OSA Biomedical Optics Express.

His visit also included a seminar talk to AOG members (and the wider academic community), titled “Multi-modal and Adaptive Optics Retinal Imaging“, whose abstract is listed below:

Optical Coherence Tomography (OCT) is used extensively in the battle against vision robbing diseases to provide diagnostic cross-sectional and volumetric images of the retina, the light sensitive tissue at the back of the eye. OCT uses the refractive elements of the eye to help focus light on the retina. However, the imperfections in the cornea and intraocular lens introduce aberrations that limit the resolution. Adaptive optics (AO), the technology used by terrestrial telescopes to image through a turbulent atmosphere, is also used for retinal imaging systems, enabling diffraction limited cellular resolution imaging of the retina non-invasively.

In this presentation, the combination of AO and OCT will be described for clinical imaging applications, with an emphasis on image-guided ‘Sensorless’ Adaptive Optics (SOA). The combination of SAO and OCT with confocal scanning laser ophthalmoscopy for single and two photon excited fluorescence retinal imaging will also be discussed.

We thank Prof Sarunic for his fascinating talk and look forward to a future visit!
