Self-Mixing Interferometer Based on Frequency Analysis Method for Accurate Refractive Index Measurement
A new method based on self-mixing interference (SMI) for refractive index measurement by means of simply frequency analysis is proposed. The optical phase shift is implemented by translating a transparent object through a motorized stage with a setting velocity. Then, the refractive index is determi...

| description | A new method based on self-mixing interference (SMI) for refractive index measurement by means of simply frequency analysis is proposed. The optical phase shift is implemented by translating a transparent object through a motorized stage with a setting velocity. Then, the refractive index is determined by the frequency of SMI fringes. A relative repeatability of refractive index estimated in <inline-formula> <tex-math notation="LaTeX">$1.0\times 10^{-4}$</tex-math></inline-formula> is achieved experimentally. This method has found that there exists an optimal velocity to achieve minimum error of refractive index measurement. |
