Fiber Laser Hydrophones, an Introductory Survey

摘要

This report is the results of a limited study of fiber laser sensors in defenseapplications. Fiber laser sensors have characteristics such as extreme strain sensitivity and small size which are useful in certain military applications. Among these, towed array sonar systems for underwater surveillance have been found to be of special interest and this report focuses on aspects related to hydroacoustics. The potentially very lightweight and small-size sensor cable, including up to 100 acoustic elements should be useful not only in special applications within this field but also generally in various kinds of towed array applications.
