6. Parabolic BM-scan technique for full range Doppler spectral domain optical coherence tomography

   Explore Article opticsinfobase.org (Jan 12 2010) Doppler

   A full range spectral domain optical coherence tomography (SD-OCT) technique that relies on the linear phase modulation of one of the interferometer arms has been widely utilized. Although this method is useful, the mirror image elimination is not perfect for samples in which regions with high axial motion exist. In this paper, we introduce a new modulation pattern to overcome this mirror image elimination failure. This new modulation is a ... (Read Full Article)

7. Adaptive optics retinal scanner for one-micrometer light source

   Explore Article opticsinfobase.org (Jan 12 2010) Ophthalmology

   We developed an adaptive optics (AO) retinal scanner by using a light source with a center wavelength of 1-um. In a recent study on optical coherence tomography (OCT), it was proved that 1-um light provided higher image contrast of deep region of the eye than 840-nm light. Further, high lateral resolution retinal images were obtained with AO. In this study, we performed measurements on two normal subjects in the AO-SLO ... (Read Full Article)

8. Generalized Jones matrix optical coherence tomography: performance and local birefringence imaging

   Explore Article opticsinfobase.org (Jan 6 2010) Dermatology , Ophthalmology

   Phase retardation imaging including local birefringence imaging of biological tissues is described by generalized Jones-matrix optical coherence tomography. The polarization properties of a local tissue can be obtained from two Jones matrices that are measured by backscattered lights from the front and back boundaries of the local tissue. The error in the phase retardation measurement due to background noise is analyzed theoretically, numerically, and experimentally. The minimum detectable phase retardation ...

    We developed a tissue discrimination algorithm of polarization sensitive optical coherence tomography (PS-OCT) based on the optical properties of tissues. We calculated the three-dimensional (3D) feature vector from the parameters intensity, extinction coefficient, birefringence, which were obtained by PS-OCT. The tissue type of each pixel was determined according to the position of the feature vector in the 3D feature space. The algorithm was applied for discriminating tissues of the human ...

    This paper presents optical coherence tomography (OCT) signal intensity variation based segmentation algorithms for retinal layer identification. Its main ambition is to reduce the calculation time required by layer identification algorithms. Two algorithms, one for the identification of the internal limiting membrane (ILM) and the other for retinal pigment epithelium (RPE) identification are implemented to evaluate structural features of the retina. Using a 830 nm spectral domain OCT device, this ... (Read Full Article)

    Polarization-sensitive optical coherence tomography enables tissue-sensitive visualization of the front of the eye. Optical coherence tomography (OCT) has become one of the most important diagnostic tools in ophthalmology. Originally used to examine the posterior eye, which includes the retina and optic nerve, it now is being applied to the anterior eye, which includes the cornea and iris.1,2 The back of the eye has several tissue layers, each with different light-scattering ...
