1. A method of monitoring operation of a reactor system, comprising:
causing a chemical reaction to occur within an assembly of the reactor system, wherein the reactor system is structured to operate at a high temperature ranging from 500° C. to 1000° C., the reactor system having a sensor system structured to implement distributed sensing that includes an optical fiber sensing member at least partially provided therein, wherein the optical fiber sensing member includes a monolithic in-fiber sensing element positioned inside the reactor assembly, wherein the monolithic in-fiber sensing element is structured to provide stable sensing at high temperatures ranging from 500° C. to 1000° C.; and
measuring at high temperatures ranging from 500° C. to 1000° C. and at a plurality of sensing locations along the monolithic in-fiber sensing element using a scattering based interrogation approach and without employing a plurality of in-fiber optic components in a core of the optical sensing member a chemical composition of one or more reactants of the chemical reaction with spatial resolution at the plurality of sensing locations, wherein the monolithic in-fiber sensing element is structured to exhibit a change in one or more optical properties in response to changes in the chemical composition of the one or more reactants.
