| Abstract: | 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. |
