摘要
分析了激光声信号的理论模型。建立了研究不同水深条件下激光声特性的实验平台。研究结果表明:当水体深度在0~100 m范围内逐渐增加时,激光声信号的两个相邻主峰时间间距越来越小;激光等离子体声波的峰值声压逐渐减小;空泡首次溃灭声波的峰值声压在0~20 m范围内逐渐增加,在20~100 m范围内逐渐减小;空泡溃灭声波峰值个数减少。
Abstract
The theoretical model of laser-induced acoustic signals is analyzed. The experimental platform is built to research characteristic of laser-induced acoustic signals. With the increase of water depth in 0~100 m, the time interval of adjacent peak pressures of laser-induced acoustic signals decreases. Peak pressures of acoustic signals induced by laser-plasma decreases. Peak pressures of acoustic signals induced by bubble collapse first increase in 0~20 m, then decrease in 20~100 m. Number of acoustic signals induced by bubble collapse decreases.
