OPTICAL FIBER APPARATUS AND A SENSING SYSTEM HAVING THE SAME APPARATUS

摘要

An elongated optical fiber apparatus for transmitting a light signal toward a first end of the apparatus situated within a fluid to be analyzed, and for transmitting a returning light signal that is indicative of a specified characteristic of the fluid toward a second end of the apparatus that is situated outside the fluid. The optical fiber apparatus includes a light conductive cable capable of transmitting light with a hole formed in its first end. Disposed substantially entirely within this hole is a reactive element that reacts with the fluid to alter a property of the light that is indicative of a specified characteristic of the fluid.
