One of the critical success parameters in carbon and glass fiber composite parts is the correct fiber orientation. For such automated inspection the method of choice is optical measurement. Carbon fiber materials appear either black or shiny bright, depending on the. Radiation absorption excites an orbital electron to a higher energy level. Heating the material enables the trapped states to interact with phonons and decay into lower-energy. A fiber optic sensor measures a physical quantity by modulating the intensity, spectrum, phase, or polarization of light traveling through the optical fiber system. Fiber-optic sensors can be designed to withstand high temperatures as well.

Optical fibers can be used as sensors to measure, , and other quantities by modifying a fiber so that the quantity to be measured modulates the,,, or transit time of light in the fiber. Sensors that vary the intensity of light are the simplest, since only a simple source and detector are required. A particularly useful feature of intrinsic fiber-optic sensors is that they can, if required, provide distributed sensing over very large distances.

In this paper, a rugged, low cost and very efficient fiber optic displacement sensor is proposed and demonstrated for the measurement of amplitude and frequency of heart rate signal. The proposed sensor is based on intensity modulation technique and uses a bundled POF as a probe. Among these sensors, optical fiber sensors (OFSs) stand out due to their remarkable properties, including resistance to electromagnetic interference. Nowadays, wearable devices are gaining broad interest for a continuous monitoring of the heart rate (HR). One of the most promising methods to estimate HR is the seismocardiography (SCG) which allows to record the thoracic vibrations with high non-invasiveness in out-of-laboratory settings.

Interferometric fiber optic current sensors (FOCS) employ circularly polarized light traversing a closed loop path around an electrical conductor's current-generated magnetic flux, which reflects off a mirror. The light experiences a reciprocal phase shift as the refractive index, and effective path length, is modulated by the presence of a magnetic field, which optically induces circular. The relative to a reference waveform is an optical intensity value corresponding to the.
