摘要
水下成像技术在军事、海洋开发和工程应用中发挥着重要的作用。然而,传统成像方法在传播过程中会受到吸收、散射、湍流和复杂的光与物质相互作用效应的影响,进而难以获得清晰的水下图像。近年来,水下鬼成像逐渐成为研究热点,它采用无空间分辨能力的桶探测器,通过关联算法来获取目标的空间分布。与传统阵列成像相比,鬼成像具有灵敏度高、抗干扰和工作波长宽等特点,在弱光、特殊波段和提高成像距离等方面具有显著优势。综述了近年来水下鬼成像的研究进展,重点讨论了其发展历程、光路结构和关键技术,分析了影响水下鬼成像质量的因素和提升方法,并对水下鬼成像的未来应用方向进行了展望。
Underwater imaging technology plays an important role in military,marine development and engineering applications.However,clear underwater images can hardly be obtained by traditional imaging methods due to the influence of absorption,scattering,turbulence,and complex interaction between light and matter in the propagation process.In recent years,underwater ghost imaging has gradually become a research hotspot.It uses a bucket detector without spatial resolution to obtain the spatial distribution of targets by the correlation algorithm.Compared with traditional array imaging,ghost imaging has the characteristics of high sensitivity,anti-interference and wide working wavelength,and it has prominent advantages in low light,special bands and increasing the detection distance of the imaging system.This paper reviews the research progress of underwater ghost imaging in recent years,focuses on its development process,optical path structure and key technologies,analyzes the factors affecting the quality of underwater ghost imaging and the improvement methods,and predicts the application directions of underwater ghost imaging.
