3D printed long period gratings and their applications as high sensitivity shear-strain and torsion sensors

R Oliveira, R Nogueira, L Bilro - Optics Express, 2021 - opg.optica.org
In this work we demonstrate the capability to measure shear-strain and torsion loads by
bonding an optical fiber to a 3D printed periodic grooved plate. The device acts as a long …
