Optical fiber couplers for various LEDs and light sensors are commercially available, but you can skip the connector and simply connect silica and plastic fibers directly to LEDs and sensors. The sensors can have both specific and different Bragg wavelengths and can be connected in series without compromising the correct reading of the measurements as long as the sensor signals do not overlap. So, grab your tools, and let's get started! Before we jump into wiring diagrams, let's quickly recap what fiber optic sensors are. Fiber optic sensing (FOS) systems can provide high-fidelity distributed strain measurements in various industries such as aerospace, automotive, structural health monitoring, and civil engineering. Proper fiber optic sensor installation is crucial to obtain accurate and useful strain measurements. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time.
