Fiber optics breaks rules of conventional sensing

摘要

Conventional sensors convert physical phenomena (such as temperature, load, pressure, and strain) into electricity, which is then conditioned, sampled, and scaled to the required physical values. Despite their ubiquity, these sensors have inherent limitations - such as transmission loss and susceptibility to electromagnetic interference (noise) - that make their usage challenging or impractical in many appli-rncations. Fiber-optic sensing is an excellent solution to these challenges, using light rather than electricity and standard optical fiber in place of copper wire to perform sensor measurements.
