| Abstract: | A simple and practical fiber grating sensor for strain and temperature measurement is presented in this paper. By using prestrain technique, two Bragg wavelengths were created by one fiber Bragg grating, and the cross sensing effect was eliminated. Linear responds to strain and temperature were achieved in the measurable ranges. |
