Comment on "Quantum Limits to Incoherent Imaging are Achieved by Linear Interferometry"
George Brumpton, Aiman Khan, Helia Hooshmand +2
We show that the construction of the linear interferometer in the Supplemental Material of arXiv:1909.09581 is flawed, leading to a generally suboptimal solution. We then provide t…
Looking down the rabbit hole: Towards quantum optimal estimation of surface roughness
Quentin Muller, Tommaso Tufarelli, Madalin Guta +3
Surface roughness is an important quantity to many engineering and precision manufacturing disciplines. In this paper we investigate the problem of estimating the root-mean-square…
Quantum Limits of Passive Optical Surface Metrology and Defect Detection
Jernej Frank, George Brumpton, Tommaso Tufarelli +2
We develop a quantum statistical framework for passive optical surface metrology. Modelling a surface as an incoherent ensemble of point emitters imaged through a diffraction-limit…
Deep Learning-based Single-Shot Composite Fringe Projection Profilometry with Pixel-Wise Uncertainty Quantification
Xiangjun Kong, Qingkang Bao, Tibebe Yalew +2
Driven by the growing demand for high-speed 3D measurement in advanced manufacturing, optical metrology algorithms must deliver high accuracy and robustness under dynamic condition…
