Title: | Fiber Bragg grating sensor for simultaneous measurement of displacement and temperature | Authors: | Yu, Y Tam, HY Chung, W Demokan, S |
Issue Date: | 15-Aug-2000 | Source: | Optics letters, 15 Aug. 2000, v. 25, no. 16, p. 1141-1143 | Abstract: | A new approach to measuring displacement and temperature simultaneously by use of a specially designed isosceles triangular cantilevered beam as a strain agent is demonstrated. A fiber Bragg grating epoxied onto the beam surface is experimentally demonstrated to have a temperature sensitivity of ∼0.113 nm/°C below 60°C and a displacement sensitivity of 9.24 × 10⁻² nm/mm. | Keywords: | Cantilever beams Optical sensors Strain measurement Strength of materials Temperature measurement Ultraviolet radiation |
