One major challenge facing the development of prominent nondestructive damage evaluation (NDE) tools has been a lack of fine spatial resolution from sensors. Advanced distributed sensing platforms resolve this issue with spatial resolution down to 1.66mm. In short, the technique uses pre- and post-damage ambient strain measurements collected from a relatively dense sensor layout provided by the fiber optic sensing platform to:
– Detect the existence of damage.
– Determine the location of damage.
– Quantify the severity of damage with very high accuracy irrespective of the size of the inflicted damage.
