Paper Abstract

A fiber optic analogue of the electrical strain rosette is proposed and shown to be necessary if two-dimensional strain fields are to be mapped using fiber optic sensors. The first fiber optic strain rosette has been constructed and preliminary testing demonstrates its ability to determine principal strain magnitudes and axis orientation. Polarimetric transduction was used for this device; the strain sensing region along each arm was localized using 45° fusion splices. This ensured that the strain rosette was lead-in and lead-out insensitive. Possible non-polarimetric designs for optical strain rosettes are also suggested.
