Abstract :
A new optoelectronic system which converts the variations of birefringence induced inside an optical resonator into an optical phase difference with a linear response over many periods is presented. This system has been applied to measure the static force by stress-induced birefringence in a fibre-optic Fabry-Perot resonator.
