Abstract

The results of application of Wiener adaptive filtering to dynamic assessment of parameters of interferometric signals formed using a partially coherent radiation source in interference profilometry and optical coherence tomography are presented. It was demonstrated that the envelope of the interference fringes and the phase step of the interferometric signals can be determined by using the obtained Wiener adaptive filter coefficients and the criterion of the minimum error dispersion relative to the formed reference signal. Experimental results of processing the partially coherent interferometric signals when determining the surface profiles and inner microstructures of objects are presented.
