深海光学照明与成像系统分析及进展

深海光学成像系统分为4个子系统:照明系统、相机系统、图像处理系统以及数据存储与传输系统,本文对深海光学成像系统化研究与发展趋势展开分析。文中有针对性地对深海光学成像最前端的两个子系统-照明系统与相机系统进行了较为详细地阐述。其中,深海照明系统进一步细分为3个更小的系统:光源系统、配光系统以及灯阵系统;对于深海相机系统则根据其应用领域及技术特点细分为水下普通成像、激光成像、偏振光成像、3D/全景成像、显微成像以及光谱成像6类。从近年来国内外深海光学成像的发展历史及现状来看,其未来的发展趋势可以归结为以下几点:更高的分辨率,更深的工作深度,更大的观测范围以及更多样的成像方式。

Analysis and research progress of deep-sea optical illumination and imaging system

The deep-sea optical imaging system is divided into four subsystems:illumination system, camera system, image processing system and data storage and transmission system. On the basis of above, a systematic study and development trend analysis of deep-sea optical imaging is conducted in this paper. Then, the two sub-systems of the forefront of deep-sea optical imaging, illumination system and camera system, are described in detail. Among them, the deep-sea illumination system is further subdivided into three smaller systems:light source system, light distribution system and lamp array system; and for the deep-sea camera system, according to its application areas and technical characteristics, it can be subdivided into 6 categories, namely, normal imaging, laser imaging, polarized light imaging, 3D/panoramic imaging, microscopic imaging and spectral imaging. Based on the history and current situation of deep-sea optical imaging both at home and abroad in recent years, its future development trend can be summarized as follows:higher resolution, deeper working depth, larger observation range and more diverse imaging method.
