Title   The principle and manufacture of Three-dimensional   seismic wave sensor                                         

Abstract Geological exploration is an important part of oil mining, but in the modern geological exploration, the exploration by human has gradually instead by the sensors, it has a higher reliability and accuracy。 So The sensor performance will directly affect the result and the difficulty of the whole geological exploration work。

Fiber optic sensor is one of the most important part, so discuss the structure of the optical fiber sensor and how the different parameters affect the sensor sensitivity and range has very important significance for improving the accuracy of the entire geological exploration。 the sensor discussed in this thesis will use the Michelson interferometer principle to process sensing signal，it belongs to light sensor Functional Fiber。 It is in a leading position at home and abroad of the sensor used in oil exploration。 It has a high sensitivity, anti-electromagnetic interference, distortion, frequency bandwidth, and other unique advantages。 It can work stable in varieties of extreme environments。

In this thesis has made a trace of the development of sensors at home and abroad, the principle of the sensors, and the sort and application of sensors。 The thesis also analyzes for the principle and structure of one-dimensional state of the seismic wave sensor。 In the finally, it has design the the structure of three-dimensional seismic wave sensor and analysis and forecast the future applications of this sensor。 During the study, we have designed and tested it by using shake table, oscilloscopes, interferometer, and other related instruments to measure the influence of the fiber winding diameter and the quality of the center mass of the optical fiber sensor to the sensitivity of sensor。 the experiment parameters and results has great reference value in the future research about different optical fiber sensors。
