报告摘要:Optical nanometrology and nanoimaging have emerged as critical domains in understanding and manipulating matters at the nanoscale, which employs light as information carrier to insight properties of objects, such as morphology, dimensions, and positions. In this presentation, we explore the structured light assisted by machine learning algorithms in localization and imaging of sub-wavelength objects with super-resolution, far beyond the diffraction limit in conventional microscopy. Here the measured objects are super sensitive to the specific structured field with giant phase gradients resulting in significant variation of scattering patterns, beneficial for machine learning analysis to achieve precise measurements. Such non-invasive and label-free metrology with negligible errors down to a few nanometers, opens a range of opportunities for smart manufacturing processes, quality control, and advanced materials characterization.
