Here, a manifold of hot spots were observed experimentally and in calculations in the gap of a ring-inner disk dielectric dimer with a rectangular cross-section.
An analysis about the back-scattering cross section from a tilted thin circular dielectric disk is presented. The proposed formulation is based upon the widely used scattering techniques from a
Optic disc cross-sections imaged by an SD-OCT. Traditional colour-film camera images are the reference standard in imaging, requiring an expert ophthalmic
We demonstrate excitation of whispering gallery modes in optical ring resonators using a gold-clad pedestal planar waveguide structure.
To our interpretation, the delineation of the optic disc border is error-prone with both instruments and all parameters directly depending on it are thus poorly correlated. However, the determination of the
In this report, we describe novel software to measure optic disc parameters in SS-OCT scans of the ONH. Generally, the distance of the reference plain from the
The results show that microdisks have advantages over microrings in these aspects, which gives instructions to the chip design of high-density
A radial cross-section through the Airy pattern (solid curve) and its Gaussian profile approximation (dashed curve). The abscissa is given in units of the wavelength
Previously, many U-Net-based optic disc segmentation methods have been proposed. However, the channel dependence of different levels of features
Images of optic disc and optic cup are acquired by fundus camera as well as Optical Coherence Tomography. The optic disc and optic cup segmentation techniques are used to isolate the relevant
Properties of the optic disc, including those indicated by color, tissue vascularization and transparency, are also lost in (narrow band) SD-OCT imaging. Therefore, in order to allow comparisons with
Ring light source installation on an inverted optical microscope. (a) Photo of a ring light source installed on the stage of an inverted optical microscope. The ring light source was installed on
The ring of Elschnig is widely accepted as the structure underpinning the fundoscopic appearance of the optic disc margin in human eyes. 1 The ring of Elschnig comprises the Border Tissue of Elschnig
The optic disc is an elevation on the retina where the nerve fibers and vessels pass through eyeball. Learn more on its anatomy and function now on Kenhub!
In this paper, a comparison between microring and microdisk modulators is well analyzed in terms of dimensions, static and dynamic power
erved experimentally and in calculations in the gap of a ring-inner disk dielectric dimer with a rectangular cross-section. In addition to dipole hot spots, galleries of equidistant hot spots were observed,
The OCT is a computer-assisted precision instrument that delineates cross-sectional anatomy of the retina and provides in vivo real time images of different structures of the eye.
ree light spots are focused on the disc. On the way back, the light di racted by the hologram propagates towards the detector region and a far-field splitting ff is obtained by sending one half circle of the

An eye with a larger optic disc tilt (red arrow) and higher amplitude retinal wave (white arrows) is shown in B and D. Cross sectional images of the peripapillary
Throughout this chapter we especially pay attention to the modelling of the signal read-out in an optical disc player and we will describe methods to efficiently calculate crucial parameters like signal jitter
Optical cross section (OCS) is a value which describes the maximum amount of optical flux reflected back to the source. The standard unit of measurement is m 2 /sr. OCS is dependent on the
Three types of optic disc images from a single study participant. Although the color disc photograpy image (A) and the optical coherence tomography (OCT) fundus image (B) were not of the same size
3.4.29 In a cross-sectional study in children, body height, axial globe length, and disc area were correlated up to childhood.28 This initial link between growth rate of body and eye may explain our
The optic disc—a tiny but powerful structure in the back of your eye—is the critical hub where visual information begins its journey. But what
To compare optic disc microvasculature measurements to the disc morphometrics in normal eyes.Cross-sectional study fty-eight healthy subjects.Enface
The purpose of this study was to compare the morphometric parameters and diagnostic performance of Stratus OCT 3000 Disc mode and HRT II in normal, suspect and abnormal optic discs.
