Random-mapped intensity optical neural network: all-optical two-layer computing for multimodal optical-field inference
Gi-Hyun Go, Doeon Lee, Gookho Song +1
Free-space optical neural networks offer distinct advantages for computational imaging and machine vision because they can compute directly on incident optical fields. However, con…

Feature-domain Fourier ptychographic tomography with dark-field illumination
Chao Tan, Fangrui Lu, Sechan Park +6
Fourier ptychographic tomography (FPT) is an implementation of intensity diffraction tomography that reconstructs three-dimensional (3D) refractive-index (RI) distributions from an…

Large-volume focus control at 10 MHz refresh rate via fast line-scanning amplitude-encoded scattering-assisted holography
Atsushi Shibukawa, Ryota Higuchi, Gookho Song +3
The capability of focus control has been central to optical technologies that require both high temporal and spatial resolutions. However, existing varifocal lens schemes are commo…
