Laser Self-Mixing Interferometer Based on Multiple Reflections and Phase-Modulation Technique
An improved method combining multiple reflections with the phase-modulation technique (MR-PM) is proposed to construct a self-mixing interferometer with high accuracy. The phase modulation is performed by using an electro-optic modulator that is placed in the external cavity. To broaden the harmonic...
