In this article we will discuss about the structure of human eye. Structure containing muscle and is located behind the iris which focuses the lens. Pads of fat and the surrounding bones of the skull protect them.

Anatomically the eye comprises two components fused into one. The retina senses light and creates impulses that are sent through the optic nerve to the brain. Figure 24a shows a perfect eye diagram.

Its wall is composed of three coats. Eye diagrams usually include voltage and time samples of the data acquired at some sample rate below the data rate. What makes up an eye.

However if the physics of the system mean that a logic one becomes so distorted while passing through the system that the receiver at the far end mistakes it for a zero this should be shown in a good eye diagram. The Uvea Of The Eye. The human eye is a roughly spherical organ responsible for perceiving visual stimuli.

Common ways of characterizing an eye are to measure the rise times fall times jitter at the middle of the crossing point of the eye the overshoot present and many other numerical descriptions of eye behavior in order to compare devices being measured. A square bit stream ie series of symbol 1s and 0s is sliced into sub-bit stream with predetermined eye intervals ie several bit periods and displayed through bit analyzing equipment eg digital channel analyzer overlapping. The rod and cone cells of the retina allow for conscious perception and vision of light including color distinction and depth perception.

Anatomy of an Eye Diagram BER Contour is a superset of the last two measurements and also the perfect linkage between BER and eye diagrams. The orbit is the bony eye socket of the skull. Hence it does not possess a perfect spherical shape.

This means that most eye diagrams are composed of shallow amounts of data. Cornea Of The Eye. For sampling oscilloscopes this can be 105 samples per second at a 10 Gbs 1010 bitssecond rate.

Now users will create a perfect graph in moments with full impact with only a few clicks. The inside lining of the eye is covered by special light-sensing. Light projects through your pupil and lens to the back of the eye.

Eyes are approximately one inch in diameter. The middle vascular coat choroid ciliary body iris. And for a description of common vision problems see Refraction and Refractive Errors.

Chris The human eye consists of the eyeball optic nerve orbit and appendages eyelids extraocular muscles and lacrimal glands. The cornea is the clear outer part of the eyes focusing system located at the front of the eye. Light enters through a central opening called the pupil.

The back part of the eyes interior. Lens Of The Eye. EdrawMax is a wondrous full-featured application commonly adopted for making the human eye diagram.

Found within two cavities in the skull known as the orbits the eyes are surrounded by several supporting structures including muscles vessels and nerves. Most of the eye is filled with a clear gel called the vitreous. Choroid Of The Eye.

It is enclosed within the eye sockets in the skull and is anchored down by muscles within the sockets. The human eye can discern nearly 10 million colors. Interpreting an eye diagram.

The iris controls widening and narrowing dilation and constriction of the pupil. Reading and applying eye diagrams An eye diagram provides a freeze-frame display of digital signals repetitively sampled. The circular opening in the centre of the iris through which light passes into the lens of the eye.

The opening in the middle of the iris through which light passes to the back of the eye. Structure of Human Eye. The outer fibrous coat sclera cornea.

The cornea pupil lens iris retina and. The eye has several major components. The light-sensitive nerve layer that lines the inside of the back of the eye.

Here are descriptions of some of the main parts of the eye. The Human Eye Eyeball Diagram Parts and Pictures Posted by Dr. The eye is cushioned within the orbit by pads of fat.

A properly constructed eye should contain every possible bit sequence from simple alternate 1s and 0s to isolated 1s after long runs of 0s and all other patterns that may show up weaknesses in the design. The White Of The Eye. Regulates the amount of light that enters your eye.

Here the decision point is stepped around the inside of the eye and the BER profile mapped out on a series of angled slices around the eye. There are 7 bones of the orbit two groups of muscles intrinsic ocular and extraocular three layers to the eyeball and thats just the beginning. With this visual representation of a signals behavior an engineer can debug and troubleshoot a digital transmission system.

In addition to the eyeball itself the orbit contains the muscles that move the eye blood vessels and nerves. The iris is the colored part of the eye that regulates the amount of light entering the eye. An eye diagram provides a simple and useful tool to visualize intersymbol interference between data bits.

Typically eye diagrams are composed of voltagetime samples of the original data acquired at some sample rate that is orders of magnitude below the data rate. The eye is a hollow spherical structure measuring about 25 cm in diameter. Layer containing blood vessels that lines the back of the eye and is located between the retina the inner light-sensitive layer and the sclera the outer white eye wall.

Anatomy of the Eye. The human eye enables vision as a conscious sense organ. Aperture Of The Eye.
