Nanosensitive optical coherence tomography for the study of changes in static and dynamic structures
(IOP Science, 2014-03-06)
We briefly discuss the principle of image formation in Fourier domain optical coherence tomography (OCT). The theory of a new approach to improve dramatically the sensitivity of conventional OCT is described. The approach ...
Characterization of an extendable multi-leaf collimator for clinical electron beams
(Institute of Physics, 2011)
An extendable x-ray multi-leaf collimator (eMLC) is investigated for collimation of electron beams on a linear accelerator. The conventional method of collimation using an electron applicator is impractical for conformal, ...
Design and performance of a small-animal imaging system using synthetic collimation.
(Institute of Physics, 2013-02-28)
This work outlines the design and construction of a single-photon emission computed tomography imaging system based on the concept of synthetic collimation. A focused multi-pinhole collimator is constructed using ...
VERITAS detection of gamma-ray flaring activity from the BL LAC object 1ES 1727+502 during bright moonlight observations
(American Astronomical Society, 2015-08-01)
During moonlit nights, observations with ground-based Cherenkov telescopes at very high energies (VHEs, E > 100 GeV) are constrained since the photomultiplier tubes (PMTs) in the telescope camera are extremely sensitive ...
VERITAS Observations of the TeV Binary LS I +61 303 During 2008-2010
(2011)
We present the results of observations of the TeV binary LS I +61 303 with the VERITAS telescope array between 2008 and 2010, at energies above 300 GeV. In the past, both ground-based gamma-ray telescopes VERITAS and MAGIC ...
1064 nm acoustic resolution photoacoustic microscopy
(Wiley, 2018-12-03)
Photoacoustic imaging is a noninvasive imaging technique having the advantages of high-optical contrast and good acoustic resolution at improved imaging depths. Light transport in biological tissues is mainly characterized ...
Portable X-ray fluorescence for the detection of POP-BFRs in waste plastics
(Elsevier, 2018-05-26)
The purpose of this study was to establish the efficacy of portable X-ray fluorescence (XRF) instrumentation as a screening tool for a variety of end of life plastics which may contain excess amounts of brominated flame ...
Label-free ultra-sensitive visualization of structure below the diffraction resolution limit
(Wiley, 2018-03-23)
For both fundamental study of biological processes and early diagnosis of diseases, information about nanoscale changes in tissue and cell structure is crucial. Nowadays, almost all currently known nanoscopy methods rely ...
Simultaneous en-face imaging of multiple layers with multiple reference optical coherence tomography
(Society of Photo-optical Instrumentation Engineers, 2017-08-22)
A technique based on multiple reference optical coherence tomography (MR-OCT) is proposed for simultaneous imaging at multiple depths. The technique has been validated by imaging a reference sample and a fingerprint in-vivo. ...
Three-dimensional depth-resolved and extended-resolution micro-particle characterization by holographic light scattering spectroscopy
(Optica, 2010)
Fourier-holographic light scattering spectroscopy is applied to record complex angular scattering spectra of two- and three-dimensional samples over a wide field of view. We introduce a computational depth sectioning ...
