This document discusses the reasons for choosing an optical sensor over an electrical sensor.
Despite the ubiquity of electrical sensors, their usage is impractical, if not entirely impossible, in certain types of applications. Fiber optic sensors offer an excellent solution to these challenges. Fundamentally, fiber optic sensors work like their electrical counterparts, but use light instead of electricity and glass fiber instead of copper wire. Where an electrical sensor might modulate electrical properties like current, resistance, or voltage, a fiber optic sensor modulates properties of light including intensity, phase, polarization, or wavelength. Learn the basics of highly differentiated fiber Bragg grating sensors, as well as available form factors and sensor types. Discover what kinds of questions to ask to determine which sensors to select for your application and how to set up complex optical sensor topologies.
