摘要：
The reversibility of holographic recording in photorefractive crystals is employed for filtering the variable noise during recording. This effect is demonstrated by the observation of phase microobjects in a medium with moving particles and fluid flows. The signal-to-noise ratio enhancement is also shown in various methods of holographic interferometry.
