A dual-polarization distributed Bragg reflector (DBR) fiber grating laser for liquid level measurement is proposed and experimentally demonstrated. The laser cavity is used as the sensing device. The liquid level is obtained by measuring the beat frequency generated between the two lasing polariza...
