Abstract: Fiber-optic sensing of temperature and strain over many advantages over electronic sensors. In this article, these sensor principles are. What are Optical Strain Sensors? Optical strain sensors (or strain gauges) are sensors for compressive and/or tensile mechanical strain (deformation) which are based on optical technology — in most cases, on fiber optics. They can be based on different operation principles as explained in the. This paper provides an overview of the different types of fiber optic sensors (FOS) that can be used with composite materials and also their compatibility with and suitability for embedding inside a composite material. Complex structures or new materials can be characterised or finite element calculations can be validated or.

Fiber optic temperature sensors are immune to the many environmental effects that compromise other measurement technologies, can be embedded and installed in locations traditional temperature sensors cannot and deliver an unprecedented level of spatial detail and data without sacrificing precision.
