| 摘 要： | 采用L9 (34)正交实验的方法,研究了弹性筒与芯轴形成的空气腔的体积、绕制探头时对光纤施加的张力这两个因素对芯轴干涉型光纤水听器声压灵敏度造成的影响.实验结果表明,空气腔体积及光纤张力对声压灵敏度没有实质影响,在光纤与弹性筒充分耦合的前提下可以不予考虑.

| Abstract: | A L9(34) orthogonal test is designed to investigate the effect of the room between the tube and the mandrel and the tension pulled on the fiber on acoustic sensitivity of interferometric fiber-optic mandrel hydrophone.Experimental results show that the room of air cavity and the tension pulled on fiber do not have much influence on sensitivity which can not be considered under the condition that the fiber and tube are fully coupled. |
