Description
Summary:A dual-modality fiber scope probe that can simultaneously obtain the spectroscopic signature and images is proposed and illustrated. The photonic crystal fiber and micro CCD camera form the probe distal end. A preliminary experimental investigation using the developed probe has been carried out on phantom tissue stained with fluorophores. Both hollow-core and double-clad photonic crystal fibers have been used at the distal end in separate embodiments, and their collection efficiencies are compared. This proposed probe and methodology are expected to find potential biomedical diagnostics applications.
