“…Gas bubble detection is a critical component of the instrumentation needed in many industrial and medical processes as well as in fundamental research of two-phase flow systems, cavitation phenomena, sonochemistry, sonoluminescence, and even biophysics of gene transport. [1][2][3][4][5][6][7][8][9] Real-time information and detection of bubble populations are required for most filling operations in the paint, food, detergent, and cosmetic industries where bubbles can compromise the final product. 10,11 In Ecology and Climate Science, bubble detection technology is required to understand the flux of greenhouse gasses, such as methane and carbon dioxide, between the ocean and the atmosphere.…”
