摘要：

Reconstruction of vibration signal is one of the key technologies for laser diode (LD) self-mixing interference used in measurement of vibration. The vibration signal is retrieved by a frequency-voltage transform from self-mixing interference signal. The transform is realized by switched capacitor through charge transfer. There are two simulative switches in the transform: one driven by self-mixing interference signal making frequency of the switch equal to frequency of self-mixing interference signal, the other driven by stimulating signal of the vibration changing the pole of charging voltage of the capacitor with phase of the vibration. Output signal amplitude of the transform is proportional to vibration amplitude. The vibration waveform rebuilt by the transform is coincident with that of stimulating signal. The frequency-voltage transform can be use to rebuild signal of arbitrary vibration if period and phase of arbitrary vibration can be extracted from self-mixing interference signal.
