Abstract

There are a large number of bubbles in ocean, such as H₂S, CH₄ and CO₂ in hydrothermal and cold springs. Bubbles in seawater are moving targets with small scale and high transparency, and it is difficult to obtain their clear optical images. In order to better image tiny bubbles, it is necessary to explore the optical characteristics of bubbles under different angles of incident light. By building a multi-angle optical characteristic analysis device for underwater bubbles, this paper collects bubble images at different incident angles, and analyzes the image characteristics of tiny bubbles. The typical bubble patterns are "hamburger" and "doughnut". In experiment, the bubble groups at different angles were collected and analyzed, and an orthogonal narrow slice imaging scheme was proposed. The optical slice imaging can obtain clear optical images of bubbles, which is conducive to quantitative analysis of bubble identification and counting in the later stage.
