摘要：
A process for velocimetric measurement of a target including causing interference in a dynamic holographic material of a reference laser beam and a beam diffused by the target, and measuring variations in luminous intensity transmitted by the material with a photoelectric detector, wherein the target vibrates with a displacement greater than the wavelength and with an extension limited around a mean position.
