Abstract

The paper shows possibilities of wavelet coherence methods for estimat ion of the optical electromagnetic radiatio n influence on biomedical signals, which characterizes the functional state of the human heart. An analysis of the wavelet coherence coefficients between pulse signals in the dark and ones under the influence of the preferred color light shows that there is a good correlation between the wavelet spectra at low frequencies and a partial correlat ion at frequencies close to the basic heart rate. Under the influence of the rejected color light, there is a good correlation of the wavelet spectra at frequencies close to the fundamental pulse rate, but there is no correlation at low frequencies.
