Photorefractive correlation filtering of time-varying laser speckles for vibration monitoring

AA Kamshilin, E Raita, K Paivasaari… - Applied physics …, 1998 - pubs.aip.org
We proposed and experimentally studied a technique of vibration object monitoring. The
technique is based on self-diffraction of the speckle pattern on the adaptive correlation filter …
