Abstract (en)
[origin: WO2016016289A1] The present invention relates to a method for extracting information of interest from a measurement signal including a periodical interference pattern, including the steps of: (i) generating a filtering function, representing the frequency components of the interference pattern, by implementing an analysis of an amplitude spectrum of the measurement signal based on morphological criteria; (ii) applying said filtering function to the measurement signal so as to generate an interference signal essentially consisting of the interference pattern; and (iii) calculating a filtered signal by determining a difference between the measurement signal and the interference signal. The invention also relates to a device implementing the method.
