Light Scattering by Bubbles in Liquids or in Glass
Abstract
This technical report consists of publications, manuscripts, and supplemental information related to the scattering of light by bubbles in liquids and in glass. The emphasis of the report is on the scattering by air bubbles in water into the angular regions where diffraction makes essential corrections to elementary ray optics. For bubbles these regions are backward, forward and critical angle scattering. Most of the previous literature on light scattering is concerned with drop-like objects where the refractive index of the scatterer exceeds that of the surroundings. The present results should be useful for the optical characterization of microbubbles at sea and in water tunnels, or for the prediction of the optical properties of bubbly media. They should also be useful for laser-Doppler anemometry with microbubbles and the detection of microbubbles in glass. Certain phenomena described here should be present for other spherical or nearly spherical scatterers where the refractive index is less than that of the surroundings, for example: air bubbles in ice, water inclusions in fused quartz (such as those present in varieties of opal glass), ice spheres in water, and superheated drops in a host liquid. The coarse structure in the critical scattering region can be present even if the scatterer is not spherical.
