Abstract
A self-mixing laser Doppler velocimeter is designed based on dual frequency laser. We can receive two beat signals and analyze them in frequency domain. The value of Doppler frequency shift is half of the distance between the two components in the power spectrum while the sign of Doppler frequency shift can be easily determined by the relative position of the two components in the power spectrum.
