Design of ultrafast fluorescence spectroscopy for axial resolution of fluorophore distribution with low numerical apertures for ophthalmologic application — •Maximilian Gräfe1, Andreas Hoffmann1, and Christian Spielmann1,2 — 1Institut für Optik und Quantenelektronik, Abbe Zentrum für Photonik, Friedrich-Schiller-Universität Jena, Max-Wien-Platz 1, 07743 Jena — 2Helmholzinstitut Jena, Fröbelstieg 3, 07743 Jena
A new method for resolving the fluorophore distribution along the propagation direction of a laserbeam is presented. For reaching spatial resolution of several tens of micrometers the time dependent fluorescence signal is sampled in the femtosecond-regime by using a technique similar to fluorescence upconversion applying optical parametric amplification. Thus this approach is applicable to fluorescence spectroscopy in the human eye.
The overall aim is to develope a method, which does not need high numerical apertures as it is necessary in confocal scanning systems.
