Liquid refractometer based mirrorless fiber optic displacement sensor
Liquid refractometer based mirrorless fiber optic displacement sensor is proposed and demonstrated. Various liquid samples with refractive index in the range of 1.333-1.433 RIU were used as modulator. The refractometer sensor was operated based on intensity modulation with regard to displacement sen...
