Patent ID: 8740455

Claim:
An apparatus for measuring environmental parameters, comprising: a carrier configured to be disposed in a borehole in an earth formation; an optical fiber sensor disposed at the carrier, the optical fiber sensor including an optical fiber having a length configured to be disposed along a path in an environment to be measured and including at least one measurement location disposed therein, the path of the optical fiber defining a longitudinal axis; and at least one section of the optical fiber sensor including a portion of the length of the optical fiber having a plurality of measurement locations extending along the portion and configured to provide environmental parameter measurements, the plurality of measurement locations of the portion of the length disposed at substantially the same location on the longitudinal axis to maintain the plurality of measurement locations at an at least substantially homogeneous environmental parameter; and a processor configured to receive the environmental parameter measurements from the plurality of measurement locations and calibrate the optical fiber sensor based on the environmental parameter measurements.
