摘要：
We propose a novel multiplexing system for sensing of dynamic strains excited in different multimode optical fibers. Multiplexing of the sensors is implemented by using vectorial wave mixing technique in the reflection geometry of hologram formation in a photorefractive crystal of CdTe:V. We analyzed different mechanisms of the crosstalk between measuring channels and showed that system performance is strongly affected by residual stresses of the photorefractive crystal.
