Speckle suppression in dynamic structured light via single-element interference

Year: 2025

Type: article

Abstract: Structured light three-dimensional (3D) measurement technology captures the depth and surface morphology of objects by projecting patterns, digitizing, and storing phase information to enable high-precision measurements. While lasers facilitate the reconstruction of fine surface features, speckle phenomena interfere with phase detection. This study introduces a dynamic stripe fluorescence measurement method based on single-element interference, suppressing laser speckles through fluorescence emission. This approach ensures high-quality stripe projection on object surfaces and facilitates accurate 3D reconstruction through a simple and easily implemented structure.
