Imaging-driven surface metrology with advanced statistical modeling

This cluster highlights how imaging and computation are transforming surface metrology, from semiconductor wafers to industrial finishes. Wooptix showcases ultra-fast, high-accuracy in-line wafer metrology at SPIE Advanced Lithography + Patterning 2026, emphasizing real-time process control in chip manufacturing. In parallel, research on wavelet Gaussian processes enables multi-scale monitoring of imaging data, such as DSLR-captured surface finishes, providing a rigorous probabilistic framework to detect subtle defects and texture changes across scales. Together, these developments point to a future where high-throughput imaging and advanced modeling enable continuous, non-contact quality assurance in complex manufacturing environments.
