| Abstract: | The optical fiber seismographs, whose sensing terminal and signal transmission link are free of electronic devices, have advantages of strong environmental adaptability and distributed networking observation, etc., and they are expected to provide new technical methods for seismic observation in deep wells, seafloor, volcanoes and other extreme environments with high density. However, there are still challenges in the design of vibration picking structure, the study of system transfer function, the suppression of noise level and the broadening of frequency band. This paper summarizes the basic principles, problems and typical cases of four types of optical fiber seismographs, including acceleration type, displacement type, strain type and rotation type. The advantages and disadvantages of the optical fiber seismographs are analyzed and discussed. And on this basis, the development prospect of optical fiber seismographs is discussed. |
