Abstract
Distributed fiber optic chemical and physical sensors can provide a relatively highly uniform response over the length of the fiber by, for example, varying such properties as the core/cladding index of refraction ratio to compensate for the non-linearity in sensitivity. The phenomenon of spatial transient over a length of a fiber introduces such a nonlinearity that can be compensated for by varying at least one parameter of the optical fiber.
