High speed fiber-optic probe for dynamic blood analysis measurements

Dynamic blood analysis requires real-time measurements. We introduce a novel optical scanning fiber-optic probe that can be used for rapidly acquiring sample data such as flow rates via doppler and dye luminescent decay kinetics over a spatial domain of interest. Experiments described demonstrate our high-speed wavelength tuned optical scanning probe concept. The scanning probe is based on wavelength multiplexing technique that offers simple control (via wavelength tuning). System issues such as probe beam scan distance, scan angle, beam spot size and optical efficiency have been addressed.
