摘　　要：为达到虚拟检测光纤水听器信号的软件程序设计的目的,采用其输出信号特点,依据非NI采集卡特性,对3×3耦合解调原理和数学模型进行分析和比较,做了干涉型光纤水听器ITT虚拟检测方案,通过调用动态链接库开发基于Lab-VIEW的数据采集程序,编写数据处理和显示程序,开发光纤水听器3×3耦合器零差解调法虚拟检测系统。得到该虚拟检测系统具有很好的幅值适应性和低频特性的结论。In order to achieve a pupose to virtual measure software program design for fiber-optic hydrophone,this paper uses characteristics of its output signals.Based on the non-NI acquisition card,the 3×3 coupler demodulation principle and its mathematical model are analysed and compared,and the interferometric fiber-optic hydrophone ITT virtual device detection program is designed.By calling a dynamic link library,the LabVIEW-based data collection program,the data processing and display program are developed,which makes up an ITT virtual detection system for fiber-optic hydrophone.Then,draws a conelusion that this virtual test system is of a good amplitude and frequency characteristics of the adaptive.
