摘要
通过分析激光束在海水中光学信道的特性,建立了激光信号海水信道传输模型。采用蒙特卡洛方法,研究了波长为530nm激光在不同杂质海水中传输时在不同接收距离处接收面上的光功率变化及3d B光斑半径的展宽。
Through the analysis of the characteristics of laser beam in seawater optical channel, water channel laser signal transmission model is established in this paper. Using the Monte Carlo method, this paper studies the wavelength of 530nm laser power change and the broadening of 3dB spot radius in different receiving dis- tance on the surface when it is transmitting in different impurities in the seawater.
