- •
The PDL parameter of identical FBGs in an array can be interrogated using the OFDR.
- •
Numerical simulation model to compute the PDL spectrum of each FBG in an array built.
- •
Design parameters studied are the length and birefringence of the FBGs.
- •
Results shows good agreement with the previous work (presented on a single FBG).
- •
Envisaged application is the monitoring of curing stages of composite manufacturing.
