Submicron Surface Vibration Profiling Using Doppler Self-Mixing Techniques

<table>PSD generated by the self-mixing signals for a sinusoidal vibration of the ACT (movement frequencies between 5 to 60 Hz). The power spectral characteristics evidence the behaviour of Doppler frequency with the ACT frequency marked with magenta dots.</table>
