Abstract

Et fiberoptisk støtfølersystem innbefatter en lyskilde, en optisk detektor og en optisk følefiber optisk koplet med lyskilden og den optiske detektoren, og den optiske følefiberen er operativt tilordnet med en ytre overflate av en struktur. Et apparat innbefatter en struktur som har en ytre overflate og et fiberoptisk støtfølersystem operativt tilordnet med den yter overflaten av strukturen. Det fiberoptiske støtfølersystemet innbefatter en lyskilde, en optisk detektor og en optisk følefiber optisk koplet med lyskilden og den optiske detektoren. En fremgangsmåte innbefatter operativt å tilordne en optisk følefiber med en ytre overflate av en struktur, overvåke et optisk utgangssignal fra den optiske følefiberen, og bestemme hvorvidt en amplitude til det optiske utgangssignalet er over eller under en forutbestemt terskelverdi.
