Paper Abstract

We propose a dual-channel fiber scanning probe for simultaneous measurement of swept source optical coherence tomography (SS OCT) and fluorescence spectroscopy (FS) signals. For the purpose, SS OCT and FS system were combined by adopting the specially fabricated double cladding fiber (DCF) and wavelength division multiplexer (WDM) coupler, and DCF fiber was directly connected to sample arm of DCF coupler for fiber-based probe. Moreover, for sample scanning, the fiber was driven by piezoelectric bender. Since DCF has dual-channel configuration consists of core and inner cladding, both OCT and FS signals propagate through the two channels at the same time. Therefore, the suggested system enables multifunctional imaging that would make it possible to determine a more specific diagnosis. To demonstrate the feasibility of the probe, a photosensitizer injected in-vivo mice were imaged with scanning speed of 16 Hz and scanning range of 2 mm.
