ABSTRACT:
An apparatus and method is described that determines the temperature distribution of an environment proximate a cable of optical fibers. No additional transducers are required to be inserted within the environment and the presence of electrical magnetic fields does not adversely affect the operation or results of the temperature measurement. The characteristic of materials which enables them to generate spontaneous thermal radiation as a function of their temperature is used to map the temperatures along the cable. A plurality of optical fibers, each having a measurably distinct absorption constant, are used in order to generate a sufficient number of known parameters to enable the temperature of a number of zones to be determined along the length of the cable. Measurement accuracy can be enhanced by the use of known heat sources in the choice of temperature zone dimensioning.
