Multifunctional sensor system

摘要: A multifunctional sensor system for an intrinsic type optical sensing fiber. numerical aperture controlling input element the excitation fiber may maximize amount of modulated return light. The be centered in a ring or linear array fibers, to inject light into poor center fiber; and capture from rich outer parts Tipping fibers with respect increase their high sizes number adjacent ends excitation, selected minimize effects any lateral displacement between ends. generate both reference light; ratiometric output signal derived which free certain errors. Ribbon-like provided; along transition if are different sizes. An annular, possibly tapered, waveguide provided around fiber, better either pass target objective; it hollow, define sample chamber objective. and/or annular mirrored, dramatically light, thus, sensitivity system.
