| 摘 要： | 给出了光散射、后向散射以及拉曼后向散射等基本概念，推导了后向散射截面与后向散射微分截面的基本关系，以及散射微分截面的计算公式。同时还得出了振动拉曼散射、振动一转动拉曼散射、转动拉曼散射、瑞利散射之间的关系。提出了利用647nm红光的拉曼后向散射检测海面以及区分海面与陆地的方法，可以有效地提高机载激光海洋测深的精度。

| Abstract: | In this paper the basic conceptions of the light scattering,backscattered and Raman backscattered,which received from the object surface,are presented.The relationship of backscattered section and backscattered differential coefficient section,and their calculating formula are derived.The relationship among the vibration Raman scattering,vibration-turn Raman scattering,turn Raman scattering,Rayleigh scattering are also deduced.In order to improve the precision of the airborne laser scanning hydrographic survey,it is suggested that 647nm Infrared of Raman backscattered be used to detect the sea level and,distinguish the sea and terrene. |
