Underwater In-Situ Monitoring Technology for Marine Organisms and Its Information Expansion in Polarization Dimensionn

Abstract

Monitoring and regulating the marine environment and reasonably developing and utilizing marine natural resources require advanced observation methods. Marine optical technology, as a mature information perception method with high spatio-temporal resolution and high-throughput data collection capabilities, plays an important role in marine scientific research. The research on polarization optics has expanded the information modality of traditional optical imaging and measurement technologies, and a large number of research and applications in ocean observation and its derivative fields represented by ecology have emerged. This paper reviewed the research progress of polarization optics technology in the field of marine environmental observation and marine biological observation. On the one hand, polarization optics assists in the in-depth analysis of complex physical processes and environmental physicochemical properties. On the other hand, polarization optics achieves incremental functions in the field of biological observation, such as expanding imaging dimensions, detecting specific targets, and recognizing biophysical and chemical characteristics. This paper also systematically introduced the models of polarization optical imaging and measurement schemes. In addition, combined with a series of works carried out by the research team in the field of underwater in-situ biological monitoring, the paper discussed the prospects of introducing polarization optics to achieve a new generation of real-time on-site monitoring systems.
