Enhancement of the signal-to-noise ratio during holographic recording in sillenite
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...

| Zusammenfassung: | 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. |
