Abstract
An optical interferometer which measures the radial pulsations of gas bubbles in liquids with Angstrom sensitivity is described. The gas-liq uid interfaces act as mirrors. The interferometer, intrinsically diffe rential, is insensitive to the overall movement of the bubble and to v ibrations of the optical components. Examples of the resonance behavio r of oxygen bubbles in water are given.
