Tomography, Optical Coherence
- Leitgeb Lab
My main research focus is to advance optical coherence tomography (OCT), for high speed and high resolution imaging of the human retina. I therefore use a line field OCT approach to parallelize one dimension. This should enable us high resolution imaging on a cellular level without the use of hardware bases adaptive optics.
Techniques, methods & infrastructure
The main technique is of course OCT at 800 and 1060nm. Using spectrometer based systems as well as swept source system, even time domain is used as one approach.
