My research efforts address optical coherence tomography (OCT). In ophthalmology this non-invasive, interferometer based, three-dimensional imaging modality helps to diagnose and monitor common eye diseases such as glaucoma, age-related macular degeneration or diabetic retinopathy. My work focuses on multi-channel approaches to investigate the aforementioned pathologic disorders. On the one hand we aim for a functional extension of OCT - namely Doppler-OCT - which enables quantitative investigation of retinal and choroidal perfusion. On the other hand our multi-channel prototypes enable investigation of the directional scattering properties of distinct layers/regions of the human retina by performing mutli-directional OCT.
