Abstract :
A novel refractive index (RI) sensor based on differential method and PSD (Position Sensitive Device) is proposed. In the paper, we systematically proposed an electro-optical measurement principle, built a mathematical model, and designed the structure of sensing probe; through detail calculation, key parameters of the refractometer are determined, simulation results showed that resolution reaches order of 10-6.
