| titleOfInvention | Liquid refractometer based on heterodyne interferometry |
| abstract | We presented a novel type of liquid refractometer. It is composed of a heterodyne light source, a coupling lens, a polarization maintaining fiber, a collimating lens, a probe module, a phase meter, a chip, and a digital display. The probe module consists of an isosceles trapezoid prism with a known refractive index, a beam-splitter, a mirror, two analyzers, and two photodetectors. The light coming from the heterodyne light source is guided by polarization maintaining fiber and incidents on the isosceles trapezoid prism of the probe module. And it is totally reflected three times in the prism. The total-internal-reflection will induce the phase difference between s-polarization and p-polarization. If the bottom of the isosceles trapezoid prism contacts the test liquid, the phase difference will be varied. According to the Fresnel's equations and the phase difference variation, the refractive index of the test liquid can be obtained. |
