FIBER OPTIC TRANSDUCERS

Fiber optic transducers are constructed from a single optical fiber wherein the geometry of the fiber is altered such as by introducing a bend or curve area in the fiber adjacent to the exit end of the fiber or by forming a canted or angled reflective surface at the exit end of the fiber. The altera...

Beschreibung
Zusammenfassung:	Fiber optic transducers are constructed from a single optical fiber wherein the geometry of the fiber is altered such as by introducing a bend or curve area in the fiber adjacent to the exit end of the fiber or by forming a canted or angled reflective surface at the exit end of the fiber. The alteration in the geometry of the fiber at or adjacent to the exit end thereof causes the light exiting from the fiber to project therefrom in a modified or expanded cone enabling more sensitive measurement capabilities.
