| 2 | Research on fiber-optic interferometric hydrophone array using frequency division multiplying technique显示文摘From the point of view of system design, a configuration of fiber-optic interferomet- ric hydrophone array and its modulation and demodulation approach using frequncy division multiplexing technique based on Phase Generated Carrier (PGC) is introduced. And the em- phasis on demonstrating the relationship among the number of units N, the detectable signal amplitude D and the detectable frequency ws through analyzing the frequency spectrum of the output signal of the J × K array and the key factor which restricts N, D, Ws for increasing are presented. The maximum phare shift and the law of its variation according to frequency are specially analyzed. The results induced from some relative theory were verified by experiments. | CAO Jianian, LI Xuyou, WANG Zhaoxia, LUO Jicheng, FU Lintai (1 Fiber-Optic Technology Institute of Harbin Bngineering University Harbin 150001) (2 Hangzhou Applied Acoustics Institute Zhejiang Fuyang 311400) | 2001 | Chinese Journal of Acoustics2001，20，4： | 0 |
