摘要:
A type of adaptive correlation filter for processing the speckle pattern emerging from an interference fiber-optic sensor is proposed. This filter is simple and self-adjustable, operating on the base of the photorefractive fanning effect. Experiments carried out with aBi12TiO20crystal and multimode optical fiber demonstrate high sensitivity and long-term stability of the sensor. ©1998 American Institute of Physics.
