High-resolution, wide-field object reconstruction with synthetic aperture Fourier holographic optical microscopy
(Optica, 2009)
We utilize synthetic-aperture Fourier holographic microscopy to resolve micrometer-scale microstructure over millimeter-scale fields of view. Multiple holograms are recorded, each registering a different, limited region ...
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 ...
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 ...
Audio frequency in vivo optical coherence elastography
(IOP Publishing, 2009-05-06)
We present a new approach to optical coherence elastography (OCE), which probes the local elastic properties of tissue by using optical coherence tomography to measure the effect of an applied stimulus in the audio frequency ...
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 ...
Interference method for determination of the refractive index and thickness
(Society of Photo-optical Instrumentation Engineers, 2000-09-01)
The interference method for simultaneous measurement of
the absolute refractive index and the thickness of plane parallel samples
is developed. This method enables us to test solid (including optical
glasses, crystals, ...
Simple characterization scheme for optical coherence tomography systems with application to a commercial and a near-isometric resolution fibre-based system
(2021-12-14)
Optical Coherence Tomography (OCT) is a rapidly
growing imaging modality in biomedical optics. OCT can perform
high-resolution, cross-sectional imaging of the microstructure of
biological tissues by measuring the coherent ...
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 ...
Microscopic particle discrimination using spatially-resolved Fourier-holographic light scattering angular spectroscopy
(Optica, 2006-11-13)
We utilize Fourier-holographic light scattering angular spectroscopy to record the spatially resolved complex angular scattering spectra of samples over wide fields of view in a single or few image captures. Without resolving ...
