Refractive Index Measurement With High Precision by a Laser Diode Self-Mixing Interferometer
A new method based on the laser diode self-mixing interference effect for refractive index measurement is demonstrated. It employs a simple translation method to measure the optical phase shift as a function of the moving distance of the sample. The refractive index is determined by analyzing a frin...
