Some analysts predict that fiber optics are about to assume a comparably important role in sensing.
Both types offer advantages that aren't available from conventional wired devices. First, radio and electromagnetic interference do not affect them, nor do they radiate energy that can affect other devices. Second, they are efficient, transmitting huge amounts of information at stupendous speeds with virtually no transmission losses. In addition, they are lightweight, are safe in explosive environments, don't corrode, and are unaffected by temperature and pressure. So far, though, the sensors have gained a significant commercial foothold, primarily in chemical and structural monitoring applications.
