Paper Abstract

A new type of fiber optical liquid refractometer based on total-internal reflection heterodyne interferometry (TIRHI) is proposed. The phase shift difference due to the TIR effects between the P and S-polarizations is measured using heterodyne interferometry with a D-type fiber sensor. Substituting the phase shift difference into Fresnel's equations, the refractive index can be calculated. It has some merits, such as, high sensitivity and stability, small size and real-time measurement.
