船舶尾流气泡幕探测技术进展与应用

本文介绍并比较船舶尾流气泡幕的声学探测和光学探测的异同。以检测参量为主线，讨论光学探测中气泡对散射光强度、频率和偏振特性的影响，重点阐述基于脉冲回波、激光拉曼散射和光学成像等探测方式的应用原理、发展状况和存在的问题。以提高回波信号信噪比为目的，提出一种基于表面等离子激元的气泡尾流探测新思路，并进行相关模拟论证。气泡尾流光学探测法及其应用系统具有实时性好、灵敏度高、探测区域广等优点，在船舶监控、海洋水体污染检测和海洋生物环境监测等方面应用广泛。

Research on optical detection of wake-bubble of vessels and ships

Acoustic and optical detection methods of wake-bubbles for ships are introduced in this paper.The influences of bubbles on intensity, frequency and polarization of scattered light are discussed in detail.It expounds the fundamentals, the development and the problems existing in different detection approaches for the wake-bubbles, which includ the pulse echo, the laser Raman scattering and the optical imaging detection.In order to improve the signal-to-noise ratio, a novel method of surface plasmon on bubble wake detection is proposed.Due to the good real-time performance, high sensitivity and wide detection area, the optical detection of wake-bubbles and its corresponding application system have the potential to be widely applied in the monitoring of ship sailing, water pollution and biotic env ironment in the ocean.
