A method of detecting the magnetic field variation is proposed and implemented experimentally. The method employs the rotation of the speckle pattern of light transmitted through an optical fiber that is placed into a longitudinal magnetic field and the recording of a holographic grating in a photorefractive crys-tal using the speckle field. The possibility of detecting the shape of a 0.15-s magnetic field pulse is demon-strated experimentally. © Pleiades Publishing, Ltd., 2011.
