Synthetic aperture Fourier holographic optical microscopy
(American Physical Society, 2006-10-18)
We report a new synthetic aperture optical microscopy in which high-resolution, wide-field amplitude and phase images are synthesized from a set of Fourier holograms. Each hologram records a region of the complex two-dimensional ...
Nanosensitive optical coherence tomography to assess wound healing within the cornea
(Optical Society of America, 2020-05-01)
Optical coherence tomography (OCT) is a non-invasive depth resolved optical imaging modality, that enables high resolution, cross-sectional imaging in biological tissues and materials at clinically relevant depths. Though ...
Noninvasive detection of nanoscale structural changes in cornea associated with cross-linking treatment
(Wiley, 2020-02-17)
Corneal cross-linking (CXL) using ultraviolet-A (UVA) irradiation with a riboflavin photosensitizer has grown from an interesting concept to a practical clinical treatment for corneal ectatic diseases globally, such as ...
Characterization of nanosensitive multifractality in submicron scale tissue morphology and its alteration in tumor progression
(Society of Photo-optical Instrumentation Engineers, 2021-01-11)
Significance: Assessment of disease using optical coherence tomography is an actively investigated problem, owing to many unresolved challenges in early disease detection, diagnosis, and treatment response monitoring. The ...
Accessing depth-resolved high spatial frequency content from the optical coherence tomography signal
(Nature Research, 2021-08-24)
Optical coherence tomography (OCT) is a rapidly evolving technology with a broad range of applications, including biomedical imaging and diagnosis. Conventional intensity-based OCT provides depth-resolved imaging with a ...
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 ...
