Self-mixing interference structure with pre-feedback used for measuring displacement

Journal Article


Abstract


  • A new self-mixing interference structure including the pre-feedback is proposed and its model is established. It is confirmed by computer simulating and experiment that the pre-feedback one can extend the measuring range and increase the signal-to-noise ratio and obtain the sawtooth interference signal from a rough surface.
