It describes the objectives and apparatus required for each experiment, outlines the theoretical foundations of optical fiber operation, and emphasizes practical applications in measuring propagation loss and signal modulation. As an instructor, you can create and edit instances of this lab, assign them to students, and view student progress.
In recent years, fiber optic sensors, primarily based on fiber Bragg gratings (FBGs), have been gradually applied in the monitoring of electrical equipment. This article provides an overview of the sensing.
There are typically two configurations used when tracking eye position with infrared reflection. One configuration uses pairs of LEDs and phototransistors (Figure 3a) while the other configuration feature.
