Smartphone-Based Refractive Index Optosensing Platform Using a DVD Grating
Sensors, 2022 A low-cost, smartphone-based optical diffraction grating refractometer is demonstrated. Its principle of operation is based on the dependence of the diffraction efficiency of a DVD grating on the surrounding refractive index.

Refractive Index Sensing by Using Mechanically Induced Long-Period Grating
IEEE Photonics Journal, 2012 In this paper, a refractive index sensor using a mechanically induced long-period grating is proposed and experimentally demonstrated. The sensing element is based on a composite optical waveguide, which is made of a single-mode fiber, a Teflon-cannula ...
