Huang, "Development and evaluation of PPP-BOTDA based optical fiber three dimension strain rosette
sensor", Optik--International Journal for Light and Electron Optics, vol.
By using this model and Raman strain rosette
technology that is proposed, the three in-plane strain components can be achieved in microscale by measuring the Raman information of CNTs randomly distributed on the measured sample with three specified polarization directions [17,18].
DMI uses laser bonded SSR (Symbolic Strain Rosette
) fatigue gages and a handheld, field-ready instrument to measure fatigue damage on a part's surface.
