The Structural Health Monitoring (SHM) process on huge structures, such as dams and bridges, can demand hundreds of sensors. Smart structures also can be a demanding application in terms of data rate or samples per second. Optical sensors are being deployed in these applications because they are inert, durable, naturally embedded in a reliable optical network and invulnerable to electromagnetic interference [6]. Differently from current wireless sensors based on digital systems, these sensors are analogic. They are based on the principle that the measured information (e.g., temperature, strain, acceleration) is wavelength-encoded in the Bragg reflection of the grating [7]. Measurand changes are coded on wavelength shift of a given Bragg sensor, which are processed by optical interrogator. Interrogators in fiber grating sensor systems are the measurand-reading units that extract measurand information from the optical signals coming from the sensor heads. The interrogators usually measure the Bragg wavelength shifts and convert the results to measurand data [8]. This data can be stored in a file or made available to client software that establishes communications with the interrogators in accordance with standard protocols.
