Fiber optics strain gauge
A fiber optics technique has been used to measure strains of less than 0.4 x 10 to the -6th power in a cantilever beam. The strain is measured as fringe motion in an optical interference pattern. The expected fringe shift per unit strain per unit fiber is found to be approximately 1.2 x 10 to the 7t...

| Zusammenfassung: | A fiber optics technique has been used to measure strains of less than 0.4 x 10 to the -6th power in a cantilever beam. The strain is measured as fringe motion in an optical interference pattern. The expected fringe shift per unit strain per unit fiber is found to be approximately 1.2 x 10 to the 7th power/m which agrees with experimental results. |
