Eliminating influence of transient oscillations on a self-mixing interferometry

Journal Article


Abstract


  • Transient oscillations occur in a self-mixing interferometry (SMI) due to moderate or strong feedback.

    Such transient dynamics appear in the form of impulsive noises and degrade the sensing performance of

    an SMI-based sensing system. However, due to the complexity of the dynamics of the system, it is difficult to

    eliminate such impulse-like transients using conventional filtering techniques. A signal processing technique

    based on myriad filter is proposed to eliminate the transients. By numerically investigating the influence of

    the parameters of myriad filter on the transients, an adaptive algorithm is developed to ensure that the

    parameters are suitable for effectively eliminating the transients. The proposed technique is verified by

    experiments, and the results show that the transients can be effectively removed, leading to improved sensing

    performance for the SMI-based sensing system
