摘要
The study of high-speed phenomena in underwater environments is pivotal across diverse scientific and engineering domains. This paper introduces a high-speed (3D) integral imaging (InIm) based system to 1) visualize high-speed dynamic underwater events, and 2) detect modulated signals for potential optical communication applications. The proposed system is composed of a high-speed camera with a lenslet array-based integral imaging setup to capture and reconstruct 3D images of underwater scenes and detect temporally modulated optical signals. For 3D visualization, we present experiments to capture the elemental images of high-speed underwater events with passive integral imaging, which were then computationally reconstructed to visualize 3D dynamic underwater scenes. We present experiments for 3D imaging and reconstruct the depth map of high-speed underwater dynamic jets of air bubbles, offering depth information and visualizing the 3D movement of these jets. To detect temporally modulated optical signals, we present experiments to demonstrate the ability to capture and reconstruct high-speed underwater modulated optical signals in turbidity. To the best of our knowledge, this is the first report on high-speed underwater 3D integral imaging for 3D visualization and optical signal communication. The findings illustrate the potential of high-speed integral imaging in the visualization and detection of underwater dynamic events, which can be useful in underwater exploration and monitoring.
