Spectral Phase Shift Interferometry for Refractive Index Monitoring in Micro-Capillaries

Spectral Phase Shift Interferometry for Refractive Index Monitoring in Micro-Capillaries

In this work, we demonstrate spectral phase-shift interferometry operating in the near-infrared wavelength range for refractive index (RI) monitoring of fluidic samples in micro-capillaries. A detailed theoretical model was developed to calculate the phase-sensitive spectral reflectivity when low-co...
