Computational Ghost Imaging [PDF]

open access: yesPhysical Review A, 2008
Ghost-imaging experiments correlate the outputs from two photodetectors: a high spatial-resolution (scanning pinhole or CCD camera) detector that measures a field which has not interacted with the object to be imaged, and a bucket (single-pixel) detector

Computational polarimetric microwave imaging [PDF]

open access: yesOptics Express, 2017
We propose a polarimetric microwave imaging technique that exploits recent advances in computational imaging. We utilize a frequency-diverse cavity-backed metasurface, allowing us to demonstrate high-resolution polarimetric imaging using a single ...

3D Computational Ghost Imaging [PDF]

open access: yesThe Rochester Conferences on Coherence and Quantum Optics and the Quantum Information and Measurement meeting, 2013
Computational ghost imaging retrieves the spatial information of a scene using a single pixel detector. By projecting a series of known random patterns and measuring the back reflected intensity for each one, it is possible to reconstruct a 2D image of ...

Metasurface optics for full-color computational imaging. [PDF]

open access: yesSci Adv, 2018
Conventional imaging systems comprise large and expensive optical components which successively mitigate aberrations. Metasurface optics offers a route to miniaturize imaging systems by replacing bulky components with flat and compact implementations ...

Just-in-time deep learning for real-time X-ray computed tomography

open access: yesScientific Reports, 2023
Real-time X-ray tomography pipelines, such as implemented by RECAST3D, compute and visualize tomographic reconstructions in milliseconds, and enable the observation of dynamic experiments in synchrotron beamlines and laboratory scanners.

Beam filtration for object-tailored X-ray CT of multi-material cultural heritage objects

open access: yesHeritage Science, 2023
Computed tomography (CT) is a powerful non-invasive tool to analyze cultural heritage objects by allowing museum professionals to obtain 3D information about the objects’ interior.

CT-based data generation for foreign object detection on a single X-ray projection

open access: yesScientific Reports, 2023
Although X-ray imaging is used routinely in industry for high-throughput product quality control, its capability to detect internal defects has strong limitations.

A novel method for dendrochronology of large historical wooden objects using line trajectory X-ray tomography

open access: yesScientific Reports, 2021
Dendrochronology is an essential tool to determine the date and provenance of wood from historical art objects. As standard methods to access the tree rings are invasive, X-ray computed tomography (CT) has been proposed for non-invasive ...
