Advantages of FOS
• Multifunctional sensing capabilities such as strain,
pressure, corrosion, temperature and acoustic signals.
• Easy integration into a wide variety of structures
• Inability to conduct electric current.
• Immune to electromagnetic interference and radio
frequency interference
• Lightweight
• Robust, more resistant to harsh environments.
• High sensitivity.
• Multiplexing capability to form sensing networks.
• Remote sensing capability.
Immune to EM waves
Ideal for microwave environment
Compact Size
Ideal for embedding and surface mounting
A fiber-optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors").
