  • Improvement of the signal-to-noise ratio in a low power self-mixing interferometer using a coupled interferometric effect 

    Yáñez Alvarado, Carlos René; Royo Royo, Santiago (2020-12-07)
    Article
    Open Access
    We present experimental results of a low-emission self-mixing interferometer that uses a coupled interferometric effect to improve the signal produced by a vibrating target. This method is intended to be useful in applications ...
