Real-time THz ptychography using an optically modulated aperture
Diksha Garg, Anil Kumar, Ian R. Hooper +6
Ptychography allows ordinary cameras to perform both quantitative phase and intensity imaging. However, the requirement for relative object to probe motion and high measurement cou…
A microwave super-resolution imaging approach towards breast cancer margin mapping
Harry Penketh, Sonal Saxena, Michal Mrnka +10
Accurate characterisation of margins in excised breast cancer tumours is critical to the success of surgical interventions. Yet margin status is typically confirmed post-operativel…
Imaging through scattering media by exploiting the optical memory effect: a tutorial
Harry Penketh, Jacopo Bertolotti
Scattering, especially multiple scattering, is a well known problem in imaging, ranging from astronomy to medicine. In particular it is often desirable to be able to perform non-in…
Terahertz imaging through emissivity control
Michal Mrnka, Harry Penketh, Ian R. Hooper +5
Adoption of terahertz technologies is hindered by the lack of cost-effective THz sources. Here we demonstrate a fundamentally new way to generate and control THz radiation, via spa…
Tracking moving objects through scattering media via speckle correlations
Y. Jauregui-Sánchez, Harry Penketh, Jacopo Bertolotti
Scattering can rapidly degrade our ability to form an optical image, to the point where only speckle-like patterns can be measured. Truly non-invasive imaging through a strongly sc…
Ghost Image Processing
Harry Penketh, William L Barnes, Jacopo Bertolotti
In computational ghost imaging the object is illuminated with a sequence of known patterns, and the scattered light is collected using a detector that has no spatial resolution. Us…
