Rugged, Sensitive Optical Fiber sensors for military sonars and monitoring military assets and earthquakes

The fiber optic sensors also called as optical fiber sensors use optical fiber or sensing element.  These Sensors can measure a large variety of parameters, such as temperature, pressure, strain, refractive index, vibrations, displacements, bending, loading, and liquid level or concentration of chemical species. Fiber optic sensors have become a focus in the field of sensing technologies by right of their many advantages such as compact, light-weighted, high sensitivity, high multiplexing, anti-electromagnetic interference and easy to be embedded into material. Following the development of optical fiber communication industry, the optical fiber sensing technologies become another major industry of optoelectronic technologies
