Design on Novel Photoelectric Sensor for Refractive Index Measurement

Abstract:

A novel photoelectric sensor based on differential method and position sensitive detector for refractive index (RI) measurement 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, preliminary experiment also verified the feasibility of the design.
