“…Its frequency shift depends on the acoustic velocity and the fiber’s index of refraction, which is affected by changes in temperature and strain. For this reason, Brillouin-distributed sensors have been used widely to monitor strain and temperature [ 40 , 41 , 42 ]. Raman scattering is also an inelastic scattering, and it is due to the molecular vibration whereby the incident light interacting with optical phonon is scattered [ 43 ].…”

“…In our previous work, an approach was developed to use an embroidering method to embed the fiber into textiles to measure temperature and strain [ 47 ]. This approach helped to improve not only the installation process but also allows the design of patterns that can be embedded in a textile as demonstrated by [ 41 ]. In this paper, distributed fiber optic sensing textile (DFOST) was designed to detect different strain directions by using one single line of fiber cable.…”

Composite polymers have become widely used in industries such as the aerospace, automobile, and civil construction industries. Continuous monitoring is essential to optimize the composite components’ performance and durability. This paper describes the concept of a distributed fiber optic smart textile (DFOST) embedded into a composite panel that can be implemented during the fabrication process of bridges, planes, or vehicles without damaging the integrity of the composite. The smart textile used an embroidery method to create DFOST for easy installation between composite laminates. It also allows different layout patterns to provide two- or three-dimensional measurements. The DFOST system can then measure strain, temperature, and displacement changes, providing critical information for structural assessment. The DFOST was interrogated by using an optical frequency domain reflectometry (OFDR). It could measure strain variation during the dynamic and static test with a spatial resolution of 2 mm and a minimum strain resolution of 10 μϵ. This paper focuses on the study of strain measurement.

A fiber optic pressure sensor that can survive 2200 psi and 140 °C was developed. The sensor’s pressure sensitivity was measured to be 14 times higher than bare FBG when tested inside stacks of ultra-high-molecular-weight polyethylene (UHMWPE) composite fabric. The sensitivity can be further improved 6-fold through the Vernier effect. Its tiny sensing length (hundreds of microns) and uniform outer diameter (125 µm) make it a suitable candidate for real-time point pressure monitoring under harsh environments with limited space, such as in composite-forming procedures.

“…Stress-strain state of the pipeline calculation is possible according to regulatory standards if there is information on the values of bending stresses acting in the controlled areas [16,27]. Recently, much attention has been paid to methods based on the use of fiber-optic sensors, which allow remotely assessing the bending of the pipeline at an arbitrary point in time during its operation [19,28,29]. For example, this system is used to monitor especially dangerous sections of the Sakhalin -Khabarovsk -Vladivostok gas pipeline with a diameter of 1220 mm.…”

“…In addition, there are VRD 39-1.10-026-2001 standards and VNIIST R-352-79 recommendations that suggest using a fixed step when surveying the pipeline axis. These approaches rely on assumptions that are not always met in practice [12,14,28]. For example, when using the chord method, a fixed distance between measurement points is required, and in calculations, according to this method, the maximum depth in the measurement area is taken as the actual depth of the pipeline axis at all measurement points.…”

Brief information about modern methods for determining the bending stresses of the extended sections of underground main pipelines without access to the pipeline generatrix is given. The necessity of modernizing methods based on determining the configuration of the pipeline axis from the soil surface with subsequent calculation of bending stresses based on the obtained data is substantiated. A mathematical model that allows to calculate the optimal parameters for surveying the axis of the pipeline from the soil surface for a pipeline of arbitrary configuration and depth, when planning a study, is proposed. Bench tests of the BITA-1 pipeline finder were carried out to determine the error in measuring the depth of the pipeline axis. It is proved that the deviations of the pipeline finder data relative to the true values in narrow depth intervals follow a normal distribution and do not change their sign. The confidence intervals of the error in determining the depth of the pipeline axis for the BITA-1 device are presented.
