| Abstract: |
| Accurate and real-time ocean current data serve as crucial input parameters for various aspects such as marine resource development, utilization, and ocean scientific research. Ocean current detection instruments are traditionally classified into four types based on measurement principles: mechanical, electromagnetic, acoustic Doppler, and acoustic time difference current meters, and novel ocean current meters combined with optical fiber sensing technology at present. In this paper, we provide a comprehensive review and summary of traditional ocean current meters and optical fiber current meters, considering detection principles, advantages, disadvantages, and current development status. We look forward to the future trends in the development of ocean current detection instruments and propose a laser-generated ultrasound flow measurement method based on continuous time difference method. The aim is to offer insights and references for the development and research of ocean current meters, contributing significantly to the advancement of ocean exploration technology and the rapid implementation of the national strategy for maritime strength. |
