Abstract
A sensor includes a sensor head including an acoustic detector configured to receive light from a first light source and to reflect the light upon incidence of acoustic waves. The sensor also includes at least one optical fiber and at least one fluorescent material within at least one of the sensor head and the at least one optical fiber. The at least one fluorescent material is configured to receive light from a second light source external to the sensor and emit visible light in response to the light received from the second light source.
