How do the parameters and characteristics of seismic-acoustic data acquisition systems affect the quality of geophysical and seismic exploration surveys?

In the case of helically-wound fiber, the frequency response depends on several key factors: integrating the measured value along the fiber based on the measurement; the angle of incidence on the cable; and the winding angle of the fiber in the cable. The authors of the article published in the journal "Mining Science and Technology" demonstrated that increasing the winding angle enhances the uniformity of the amplitude-frequency characteristics of longitudinal waves both in terms of frequencies and angles of incidence. At the same time, helical winding changes the effective response spacing (gauge length). This makes it possible, by summing the responses of the straight and helically-wound fibers due to the overlap of the spectra, to record frequencies that are suppressed in case of separate recording.
