Real-time quantitative visualization of 3D structural information
(Optica, 2012)
We demonstrate a novel approach for the real time visualization and quantification of the 3D spatial frequencies in an image domain. Our approach is based on the spectral encoding of spatial frequency principle and permits ...
Spectral encoding of spatial frequency approach for characterization of nanoscale structures
(American Institute of Physics, 2012-07-17)
An approach to acquire axial structural information at nanoscale is demonstrated. It is based on spectral encoding of spatial frequency principle to reconstruct the structural information about the axial profile of the ...
Feasibility of correlation mapping optical coherence tomography angiographic technique using a 200 kHz vertical-cavity surface-emitting laser source for in vivo microcirculation imaging applications
(Optica, 2018-08-01)
Optical coherence tomography (OCT) angiography is a well-established in vivo imaging technique to assess the overall vascular morphology of tissues and is an emerging field of research for the assessment of blood flow ...
Functional imaging for regenerative medicine
(BMC, 2016-04-19)
In vivo imaging is a platform technology with the power to put function in its natural structural context. With the drive to translate stem cell therapies into pre-clinical and clinical trials, early selection of the right ...
VERITAS 2008 - 2009 monitoring of the variable gamma-ray source M87
(2010)
M87 is a nearby radio galaxy that is detected at energies ranging from radio to VHE gamma-rays. Its proximity and its jet, misaligned from our line-of-sight, enable detailed morphological studies and extensive modeling at ...
Discovery of TeV Gamma Ray Emission from Tycho's Supernova Remnant
(2011)
We report the discovery of TeV gamma-ray emission from the Type Ia supernova remnant (SNR) G120.1+1.4, known as Tycho's supernova remnant. Observations performed in the period 2008-2010 with the VERITAS ground-based gamma-ray ...
A recent change in the optical and gamma ray polarization of the Crab nebula and pulsar
(Oxford journals, 2015-12-31)
We report on observations of the polarization of optical and γ-ray photons from the Crab nebula and pulsar system using the Galway Astronomical Stokes Polarimeter (GASP), the Hubble Space Telescope, Advanced Camera for ...
Characterization of an amplified piezoelectric actuator for multiple reference optical coherence tomography
(Optica, 2018-08-30)
The characterization of an amplified piezoelectric actuator (APA) as a new axial scanning method for multiple-reference optical coherence tomography (MR-OCT) is described. MR-OCT is a compact optical imaging device based ...
