Dataset for MMF nano-displacement detection

This dataset contains two sets of raw speckle data collected by the multimode fiber nano-displacement detection system: 1. Different detected patterns: This folder contains speckle fields with different displacements when detecting target's patterns changes (256×256 pixels, grayscale). 2. Wafer Detection Dataset: This folder contains speckle fields with different displacements of wafers detected with fiber probes (256×256 pixels, grayscale).
