A new algorithm for path selection in Automatically Switched Optical Networks is presented and demonstrated. This algorithm is based upon Eye Closure Penalty and involves a simple modification of the current OSPF protocol. ASON, path selection, OSPF, Eye Closure Penalty

It was predicted that due to the optical distortion produced.by wearing a facemask, the constancy of visual position would not be maintained under water, i. e., stationary objects should appear to move when the head is moved. Subjects made magnitude estimates of object movement in both air and water. Twice as much movement occurred in water as in air. Two underwater activities, head rotation wh...

We propose a new technique to reduce influence of timing jitter at an optical RZ receiver using Kerr nonlinearity in normal dispersion fibers, and investigate the effectiveness of this technique by means of eye penalty and eye opening width.

The optical quality of a living eagle's eye was determined by an ophthalmoscopic method. The performance of the eye was substantially better than that reported for humans, but did not confirm some of the wilder claims made for such birds.

A rapid and convenient method has been developed to facilitate the alignment of the image-plane components of point-diffraction interferometers, including the phase-shifting point-diffraction interferometer. In real time, the Fourier transform of the detected image is used to calculate a pseudoimage of the electric field in the image plane of the test optic where thecritical alignment o f vario...

Optical coherence tomography angiography (OCT‐A) is a non‐invasive imaging modality for assessing the vasculature within ocular structures including retina, macula, choroid and optic nerve. OCT‐A has wide range of clinical applications in various optometric conditions which have been independently reported literature. This paper aims to present review current literature on application practice ...
