An optical interferometer which measures the radial pulsations of gas bubbles in liquids with Angstrom 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 of the optical components. Examples of the resonance behavior of oxygen bubbles in water are given

Abstract
An optical interferometer which measures the radial pulsations of gas bubbles in liquids with Angstrom 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 of the optical components. Examples of the resonance behavior of oxygen bubbles in water are given
