An optical interferometer which measures the radial pulsations of gas bubbles in liquids withAngstrom sensitivity is described. The gas-liquid interfaces act as mirrors. The interferometer,intrinsically differential, is insensitive to the overall movement of the bubble and to vibrations ofthe optical components. Examples of the resonance behavior of oxygen bubbles in water aregiven.

Abstract
An optical interferometer which measures the radial pulsations of gas bubbles in liquids withAngstrom sensitivity is described. The gas-liquid interfaces act as mirrors. The interferometer,intrinsically differential, is insensitive to the overall movement of the bubble and to vibrations ofthe optical components. Examples of the resonance behavior of oxygen bubbles in water aregiven.
