Spectral domain second-harmonic optical coherence tomography

Optics Letters, 2005
Optical coherence tomography (OCT) provides micrometer-scale structural imaging by coherent detection of backscattered light. Molecular contrast in OCT has been demonstrated using transient absorption, coherent anti-Stokes Raman scattering, and second-harmonic (SH) generation.

Polarization sensitive spectral domain optical coherence tomography

SPIE Proceedings, 2005
We developed a polarization sensitive spectral domain optical coherence tomography (PS-SD-OCT) system. To demonstrate the performance of our system we measured the distribution of retardation of a highly birefringent plastic sample. We recorded also images of intensity and retardation of the fovea region and the optic nerve head of a healthy volunteer.

Spectral-domain optical coherence tomography of macula in myopia

International Ophthalmology, 2015
The aim of this study is to determine the associations between regional macular thickness and gender, age, axial length, and degree of myopia in young and middle-aged healthy myopic eyes. One hundred and seventy-one subjects with -0.5 diopters of myopia or worse underwent prospective macular thickness measurement by Spectralis spectral-domain optical ...

Spectral-domain optical coherence tomography with a Fresnel spectrometer

Optics Letters, 2012
We propose a novel spectral-domain optical coherence tomography (SD-OCT) equipped with a Fresnel spectrometer, which utilizes a Fresnel zone plate (FZP) as both dispersion and focusing optics and thus spreads the spectral interferogram evenly in wavenumber domain because of the proportional relation between the focal length of the FZP and the ...

FEASIBILITY OF INTRASURGICAL SPECTRAL-DOMAIN OPTICAL COHERENCE TOMOGRAPHY

Retina, 2011
To evaluate the feasibility of intrasurgical spectral-domain optical coherence tomography in a pilot study.Using a Carl Zeiss Meditec Cirrus HD-OCT system adapted to the optical pathway of a Zeiss OPMI VISU 200 surgical microscope, 512 × 128 macular cube scans were performed during various steps of microsurgical procedures in 25 cases.

COMMOTIO RETINAE WITH SPECTRAL-DOMAIN OPTICAL COHERENCE TOMOGRAPHY

Retina, 2011
To characterize retinal changes in areas of commotio retinae using spectral-domain optical coherence tomography.In this retrospective observational case series, we included 14 eyes of 14 patients who had experienced blunt ocular trauma and underwent spectral-domain optical coherence tomography and fundus photography evaluation on the same day.

Spectral calibration in spectral domain optical coherence tomography

Chinese Optics Letters, 2008
A novel spectral calibration method is developed for spectral domain optical coherence tomography system. The method is based on two measurements of interference spectra from two reference mirror positions. It removes the influence of dispersion mismatch, and hence accurately determines the spectral distribution on the line-scan charge-coupled device ...

Spectral/Fourier Domain Optical Coherence Tomography

2008
Optical coherence tomography (OCT) is a powerful diagnostic imaging tool with which multiple quantitative and qualitative studies on diseases of the eye have been performed. 1–7 Optical coherence tomography imaging is analogous to ultrasonic imaging, except that it measures echo time delays of light instead of sound.
