“…Optical fiber-based accelerometers have an even higher developments and applications, since they are not only used in navigation systems, but also in structural health monitoring [ 135 ] and physiological parameters monitoring [ 136 ]. To that extent, the optical fiber-based accelerometers were developed using different OFS approaches, as thoroughly discussed in [ 137 ].…”

Smart sensing for aeronautical applications is a multidisciplinary process that involves the development of various sensor elements and advancements in the nanomaterials field. The expansion of research has fueled the development of commercial and military aircrafts in the aeronautical field. Optical technology is one of the supporting pillars for this, as well as the fact that the unique high-tech qualities of aircrafts align with sustainability criteria. In this study, a multidisciplinary investigation of airplane monitoring systems employing optical technologies based on optical fiber and nanomaterials that are incorporated into essential systems is presented. This manuscript reports the multifunctional integration of optical fibers and nanomaterials for aircraft sector discussing topics, such as airframe monitoring, flight environment sensing (from temperature and humidity to pressure sensing), sensors for navigation (such as gyroscopes and displacement or position sensors), pilot vital health monitoring, and novel nanomaterials for aerospace applications. The primary objective of this review is to provide researchers with direction and motivation to design and fabricate the future of the aeronautical industry, based on the actual state of the art of such vital technology, thereby aiding their future research.

“…This technology permits high interrogation taxes in the order of 35 kSps, with the cost of a single spectrometer interrogation channel (OEM spectrometers, Ibsen photonics). Although the two technologies are a well-matured solution and facilitate the implementation of the sensors in different areas, they represent an elevated cost for the interrogation system, which shows the scienti c community's interest in developing alternative techniques for the fabrication of interrogators (Díaz et al 2018;Xiaolin et al 2021;Dos Santos et al 2019).…”

Optical ber sensors have great potential for application in civil construction, especially in the eld of structural health monitoring. However, one of the barriers to the diffusion of these sensors is allied to the fact that their implementation is quite expensive, mainly due to the high price of commercial optical interrogators. Therefore, the present work seeks to develop a low-cost optical interrogation system. For this, the present study proposes the development of this system based on the use of tunable lters and edge lters in the monitoring of low and high frequencies, and consequent digital processing of the collected signals through the nd_picks algorithm and the Fourier transform. As a result, it was possible to observe the adequate functioning of the tunable lters, with the validation of the system using a FBG, and a previous simulation for the edge lter system with frequencies superior to 100 kHz.

However, one of the barriers to the diffusion of these sensors is allied to the fact that their implementation is quite expensive, mainly due to the high price of commercial optical interrogators. Therefore, the present work seeks to develop a low-cost optical interrogation system. For this, the present study proposes the development of this system based on the use of tunable filters and edge filters in the monitoring of low and high frequencies, and consequent digital processing of the collected signals through the find_picks algorithm and the Fourier transform. As a result, it was possible to observe the adequate functioning of the tunable filters, with the validation of the system using a FBG, and a previous simulation for the edge filter system with frequencies superior to 100 kHz.
