Abstract: The kinematics and dynamics of the underwater bubble is always one of important research issues. The high-speed imaging and the load test technologies provide excellent tools for studying the bubble's behavior. The development and the applications of the high-speed imaging and the load test technologies for bubble dynamics are reviewed in this paper. Firstly, the origin and the classification of bubbles are briefly summarized; secondly, the high-speed imaging on capturing the bubble's deformation is reviewed and analyzed; thirdly, the bubble load test equipment and technologies are discussed; lastly, the problems needed to be studied further are suggested.
