An optoelectronic oscillator-based strain sensor with extended measurement range

ABSTRACT An optoelectronic oscillator (OEO)‐based strain sensor with extended measurement range is proposed and demonstrated. The OEO is embedded with an electrical phase shifter (EPS) to cancel out the strain‐induced phase shift real‐timely via a phase‐locked loop scheme. Theoretically, the control...
