摘　　要：该文提出并实验验证了一种可通过磨砂玻璃滤光片诱导的浴帘效应来抑制水下噪声的方法.在实验中,在水槽中的水被蓝色墨水污染,以添加随机分布的散射颗粒,并使用蠕动泵产生湍流噪声.携带图像信息的扩展光束穿过水槽,进入电荷耦合器(CCD)用于图像记录.对比结果表明:由于磨砂玻璃滤光片起到空间低通滤光的作用,所以可以大大提高记录图像的可见度;通过高斯拉普拉斯(LoG)算法和人工智能算法,插入磨砂玻璃滤光片的图像处理效果也优于没有磨砂玻璃滤光片的.该方法方便且经济,在资源勘探和海底考古中具有潜在的应用价值.The handy and economical way of suppressing the underwater noise via the frosted glass filter inducing show curtain effect is theoretically proposed and experimentally demonstrated.In the experiment,the water contained in the flume is deliberately polluted by the blue ink to add the randomly distributed scattering particulates and the peristaltic pump is applied to produce the turbulence noise.The expanded light beam carrying the picture message passes through the water-filled flume and enters into the CCD for recording the image.The comparison results show that the visibility of recorded image can be greatly improved by inserting the frosted glass filter since it acts as a spatial low-pass filter.The image processing consequences with frosted glass filter inserted by means of LoG algorithm and artificial intelligence algorithm are also superior to those of the case with no frosted glass filter.Our underwater noise suppression method can have potential applications in the resource exploration and seabed archaeology.
