The optical cord allows you to measure elongation variations within a structure in order to determine stress concentrations.

It is also able to deliver up to 18 conclusive behavioral data:

	Deformation stability
	Compression
	Tension
	Stability of neutral axes
	Displacement of the neutral axis
	Amplitude
	Elasticity
	Viscoelastic behavior
	Long cycles

	Frequency
	2° and 3° oscillation mode
	Synchronization of two distant points
	Counting
	Traces of micro-cracks in tension
	Traces of micro-cracks in compression
	Traces of micro-cracks and irreversible shocks
	Location of a break
	Speed ​​of the event
