Abstract: |
Accurate and real-time ocean current data serve as crucial input parameters in various domains such as marine resource development, marine resource utilization, and oceanic scientific research. Traditionally, ocean current detection instruments fall into four categories based on detection principles: mechanical, electromagnetic, acoustic Doppler, and acoustic time difference ocean current meters. Presently, novel ocean current meters incorporating optical fiber sensing technology exist. In this paper, we provide a comprehensive review and summary of both traditional and optical fiber-based ocean current meters, covering their detection principles, advantages, disadvantages, application areas, and current development status. Considering the future trends in the development of ocean current detection instruments, we propose a laser-generated ultrasound flow measurement method based on the continuous time difference method. Our aim is to offer insights and references for the development and research of ocean current meters, significantly contributing to the advancement of ocean exploration technology and the rapid implementation of national strategies for maritime strength. |
