文摘

Patch-based fringe patterns with little harmonic distortion. Proactively-optimized patches that are robust to defocusing extent. Octa-level fringe patterns of arbitrary fringe period. Sharing the same advantages with the systems using binary fringe patterns. Remarkably improved measuring performance.
