摘要
提出一款适用于海面溢油激光探测系统的接收装置,通过对该装置中的平行光管、光学天线以及积分球等光学部件进行研究,分析了激光在装置中的能量传输变换等系列问题。然后,以不同油膜厚度对应的激光反射信号强度作为仿真参数,在不同海况下验证了接收装置的有效性。结果表明,同一油膜厚度下,经过接收装置的激光强度远小于未经过接收装置的激光强度,此外,在平静海面或风速为0.3、0.5和0.8 m/s的微浪海面下,使用经过接收装置后的激光强度可以有效反演海面油膜厚度。
A receiver device for a sea surface oil spill laser detection system is proposed,and a series of problems,such as energy transmission and the transformation of the laser in the device,are analyzed by studying the optical components of the device,such as the parallel light tube,optical antenna,and integrating sphere.Then the effectiveness of the receiving device is verified under different sea conditions by taking the laser-reflected signal intensity corresponding to different oil film thicknesses as the simulation parameter.The results show that for the same oil film thickness,the laser intensity after the receiving device is much smaller than that without the receiving device.In addition,in a calm sea or in a slightly wavy sea with wind speeds of 0.3,0.5,and 0.8 m/s,the laser intensity after the receiving device can be used to effectively invert the thickness of the oil film on the sea surface.
