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...
