Abstract
Initial flight tests of a fiber optic strain gauge based on a balanced double-polarization Michelson interferometer have been performed. The sensor was fixed on a carbon fiber reinforced plastic plate which, in turn, was screwed to the main wing spar of a Cessna C207A aircraft. Strain was monitored under different flight conditions and compared to the readout of a conventional resistive strain gauge.
