报告内容:
Optical metrology, which uses light to precisely measure and characterize objects, is essential in industrial manufacturing, scientific research, and engineering design. Computational optical imaging techniques have leveraged novel optical systems, advanced algorithms, and increased computing power to accurately reconstruct and analyze the physical properties of objects, surpassing the capabilities of traditional optical metrology methods. This talk will explore several advancements in optical metrology through computational imaging techniques. First, I will introduce a novel Fourier Ptychographic Topography (FPT) system that delivers a wide field-of-view, high resolution, and nanoscale accuracy in semiconductor surface topography measurements, outperforming conventional profilometry techniques. Second, by leveraging a multiple-scattering beam propagation model (BPM), I will demonstrate enhanced 3D particle detection from a single hologram, achieving superior accuracy, particularly in dense particle fields and deep imaging scenarios. Finally, I will present the Neural Phase Retrieval (NeuPh) network, which offers flexible object representation and superior phase retrieval performance.
