Using Matlab software developed by the authors, two relational expressions indicating the inflection of the wedge angle and the optical axis inclination angle both on the splitting angle ε and the plane of apparent splitting inclination angle η were calculated.

In order to get higher accuracy of amplitude measurement and suppress the respiration interference of the photoelectric pulse wave,the original pulse wave signal was processed by the characteristic parameter reconstruction based on the coherent averaging method combined with the wavelet analysis.

First,it integrates the wavelet transform modulus maxima method with the signal coherent averaging technique to construct the ECG template.

The paper presents a novel adaptive harmonic detecting algorithm using the coherence average estimation of K(n)to control the updating of the step size,where K(n)is the proportion of the error signal e(n)in the total signal S(n).

A detection method for weak signal with coherence average is presented,and the principle of cross-correlation detection is introduced.

A novel approach to micro-displacement detection of dams based on Support Vector Machine and coherence average denoising is proposed.

By using the concept of ”coherence area”, we standardized three familiar statements about the spatial coherence criterion on a photon correlation spectrum measurement system.
