A method and system for determining strain impressed on an optical fiber at a possibly indeterminate temperature. The fiber (14) is formed with at least two sensors having different strain and temperature characteristics, preferably a Bragg Fabry-Perot sensor having a Fabry-Perot cavity (16) formed between...http://www.google.fr/patents/US6947637?utm_source=gb-gplus-shareBrevet US6947637 - Measurement of fiber strain during processing
