Abstract:In the nerve system, the optical fibers are the information carrier and along their length are the fiber sensors, or nerve endings, which are used to sense the environment. They can be readily incorporated into new construction or retrofitted into existing infrastructure.
The information from these "nerves" (optical fibers) and "nerve endings" (fiber optic sensors) is carried to optical/electronic demodulators. These demodulators do a rudimentary sorting of the information, similar to that occuring in the lower part of a brain. This first-level processing is similar to the overall "awareness level" of nerves in a human body. For some fiber optic sensor systems this is all the sophistication required. Environmental effects are simply recorded when they happen.
