Review of 3D Imaging by Coded Aperture Correlation Holography (COACH)
TL;DR: Coded aperture correlation holography (COACH) as discussed by the authors is a relatively new technique to record holograms of incoherently illuminated scenes, and it has been widely used for 3D super-resolution imaging and partial aperture imaging.
Journal ArticleDOI
Attenuated Total Reflection at THz Wavelengths: Prospective Use of Total Internal Reflection and Polariscopy
Meguya Ryu,Soon Hock Ng,Vijayakumar Anand,Stefan Lundgaard,Jingwen Hu,Tomas Katkus,Dominique R. T. Appadoo,Zoltan Vilagosh,Andrew Wood,Saulius Juodkazis,Junko Morikawa +10 more
TL;DR: In this paper, the attenuated total reflection (ATR) at THz wavelengths for increased sub-surface depth characterisation of (bio-)materials is presented, and the sensitivity of the polarised ATR mode to the refractive index between the sample and ATR prism is numerically modelled and experimentally verified for background (air) spectra.
Journal ArticleDOI
All femtosecond optical pump and x-ray probe: holey-axicon for free electron lasers
Vijayakumar Anand,Jovan Maksimovic,Tomas Katkus,Soon Hock Ng,Orestas Ulčinas,Mindaugas Mikutis,Justas Baltrukonis,Antanas Urbas,Gintas Šlekys,H. Ogura,Daisuke Sagae,Tatiana Pikuz,Toshihiro Somekawa,Norimasa Ozaki,Arturas Vailionis,Gediminas Seniutinas,Vygantas Mizeikis,Karl Glazebrook,Jean P. Brodie,Paul R. Stoddart,Ludovic Rapp,Andrei Rode,Eugene G Gamaly,Saulius Juodkazis +23 more
TL;DR: In this paper, a co-axial pump (optical)-probe (x-rays) experimental concept and show performance of the optical component are presented and different realisations of optical pump are discussed.
Journal ArticleDOI
Edge and Contrast Enhancement Using Spatially Incoherent Correlation Holography Techniques
Vijayakumar Anand,Joseph Rosen,Soon Hock Ng,Tomas Katkus,Denver P. Linklater,Elena P. Ivanova,Saulius Juodkazis +6 more
TL;DR: In this article, an iterative algorithm that can yield from the experimentally recorded point spread function (PSF), a synthetic PSF that can generate edge-enhanced reconstructions when processed with the object hologram is presented.
Journal ArticleDOI
Invasive and Non-Invasive Observation of Occluded Fast Transient Events: Computational Tools
TL;DR: This study compares imaging requirements and performances with invasive and non-invasive modes when a fast transient event is occluded by a metal window consisting of numerous holes punched through it andmented MATLAB codes are provided for both invasive andNon-Invasive modes of reconstruction.
