Study on Laser Transmission Characteristics of Wake Bubble Curtain

School of Sciences, Xi'an Technological University, Xi'an 710021, China

摘要

摘要: 舰船在航行过程中会产生尾流区域, 激光穿过气泡尾流区域时会发生散射现象, 通过对散射光的探测和分析, 能达到对舰船的探测与识别的目的。文中探究尾流气泡幕对激光传输特性的影响, 基于光纤光谱仪探测尾流气泡幕的光强变化。实验模拟了不同压强下的尾流气泡幕在距离水面5 cm以及距离水面15 cm和20 cm气泡幕的厚度分别为10 cm和15 cm时的尾流气泡幕光强变化, 同时也探究了前向散射和后向散射的光强随压强的变化情况。实验结果表明, 随着压强的增大, 光强变化逐渐降低, 气泡浓度与气泡半径也随之增大; 气泡浓度越大, 光强变化越小; 随着压强的增大, 前向散射光强逐渐呈线性降低, 而后向散射光强则会随之增大。

Abstract: In the wake region generated in the course of navigation, the scattering phenomenon occurs when the laser passes through the wake region of the bubble. Through the detection and analysis of the scattered light, the purpose of detecting and identifying the ship can be achieved. In this paper, the influence of wake bubble curtain on laser transmission characteristics is investigated, and the light intensity change of wake bubble curtain is detected based on fiber optic spectrometer. The laboratory simulated the change of light intensity of wake bubble curtain under different pressures when the thickness of wake bubble curtain 5 cm away from the water surface and 15 cm and 20 cm away from the water surface were 10 cm and 15 cm respectively, and also explored the change of light intensity of forward scattering and backward dispersion with the change of pressure. The experimental results show that the variation of light intensity decreases with the increases of pressure. When the pressure increases, the concentration of the bubble also increases, and the radius of the bubble will also increases with the increases. The higher the bubble concentration, the smaller the change of light intensity. With the increase of forward scattered light gradually decreases and linearly changes, while the intensity of backward scattered light increases with the increase of air pressure.
