Steady developments in cost and reliability in fiber optic sensors have seen an increase of their deployment in numerous monitoring and detection applications. In high-end applications, greater resolution is required, especially in systems where the environment is quiet, but the signal is weak. In order to meet these requirements the most dominant noise source, laser frequency noise, must be reduced. In this paper we present a quasi-static strain sensing referenced to a molecular frequency...[Show more]
