Measurement of angular distributions by use of low-coherence interferometry for light-scattering spectroscopy [PDF]

open access: yes, 2001
We present a novel interferometer for measuring angular distributions of backscattered light. The new system exploits a low-coherence source in a modified Michelson interferometer to provide depth resolution, as in optical coherence tomography, but ...

Optical coherence tomography and scanning laser ophthalmoscopy: Approaches to dual-channel retinal tissue imaging [PDF]

open access: yes, 2014
We report a Talbot bands-based optical coherence tomography (OCT) system capable of producing longitudinal B-scan OCT images and en-face scanning laser ophthalmoscopy (SLO) images of the human retina in-vivo, with various degrees of ...

Artifacts in optical coherence tomography [PDF]

open access: yesSaudi Journal of Ophthalmology, 2014
Optical coherence tomography (OCT) is now an integral part of management for numerous retinal diseases for diagnosis, treatment planning and follow up. OCT interpretation must involve the understanding of the associated artifacts. These artifacts can mislead physicians to wrong diagnosis or inappropriate management.

Inverse scattering problem for optical coherence tomography [PDF]

open access: yes, 2003
We deal with the imaging problem of determining the internal structure of a body from backscattered laser light and low-coherence interferometry. Specifically, using the interference fringes that result when the backscattering of low-coherence light is ...

Doppler Optical Coherence Tomography

open access: yesProgress in Retinal and Eye Research, 2014
Optical Coherence Tomography (OCT) has revolutionized ophthalmology. Since its introduction in the early 1990s it has continuously improved in terms of speed, resolution and sensitivity. The technique has also seen a variety of extensions aiming to assess functional aspects of the tissue in addition to morphology. One of these approaches is Doppler OCT

Investigation of Light Parameters on Image Quality and Optical Coherence Tomography

open access: yesInternational Journal of Optics, 2021
In this work, image quality and optical coherence tomography were studied. The results of the study show that there is a very significant difference between ultrasound and optical coherence tomography to produce an image with a different wave.
