Eye Diagram

An eye diagram is the most commonly used method of evaluating the performance of digital data communication systems and is also applied to optical fiber networks. The eye diagram provides valuable information on the optical link performance, such as the signal distortion, rise time, noise margin, and timing

The visible spectnun extends from about 4000 A to 7000 A. We find that the eye acts as an integrating instrument. Thus, two colors may appear equal to the eye even though one is monochromatic light and the other has a bcuid of wavelengths. This is shown in the following diagram ... 

It was soon determined that the 1931 CIE chromaticity diagram, and lumincmce function, Y, are not representative of equal visual spacing, that is, equal changes in Y do not represent equal changes in visual perception for all values of Y. Nor do equal increments of x and y represent the same visual effect for all locations on the chromaticity diagram. In other words, there is a minimum perceptual difference on both x and y (i.e.- Ax and Ay). But, the size of Ax and Ay is not the same at all parts of the chromaticity diagram. This is the same problem that Munsell encountered and is due to the fact that the human eye is...

The sensation of colour that we experience arises from the interpretation by the brain of the signals that it receives via the optic nerve from the eye in response to stimulation by light. This section contains a brief description of the components of the eye and an outline of how each of these contributes to the mechanism by which we observe colours. Figure 2.2 shows a cross-section diagram of the eye, indicating some of the more important components.

( ) ODT (o) OOT ( ) dilute solution critical micelle temperature, cmt. Subscript 1 identifies phase as normal (PS chains reside in minor domains) subscript 2 indicates inverted phases (PS chains located in major domains). Phase boundaries are drawn as guide to eye, except for DOP in which OOT and ODT phase boundaries (solid lines) show previously determined scaling of PS-PI interaction parameter (xodt

Figure 4. Views of DMBA, BP, 5,6-dimethylchrysene, 5,12-dimethyl-chrysene and 5-methyl chrysene. These illustrate the distortions that occur as a result of steric effects. These and many subsequent representations of molecular structure are stereoviews and may be viewed with stereoglasses alternatively the reader can focus his eyes on the two images until an image between them begins to form and then allow his eyes to relax until the central image becomes three-dimensional. This process calls for patience and may take a minute or so. The reader who does not wish to do this may simply inspect one of the two diagrams for each structure.

The arrows indicate the electron spin, the thin horizontal gray line is a guide to the eye. In this representation, coulomb and exchange energies are explicitly included in the positions of the frontier orbitals...

FIGURE 2.2 A diagram of human skin. Epidermal thickness depends upon body site being thickest on the palms and soles (-1500 pm) and thinnest around the eyes (-10 pm). The stratum corneum is the only layer composed of anucleated, terminally differentiated kerati-nocyte cells called corneocytes. All other epidermal layers contain nucleated keratinocytes. The dermis is composed primarily of the structural proteins collagen and elastin. 

Structures of the anterior chamber of the eye. Tissues with significant autonomic functions and the associated ANS receptors are shown in this schematic diagram. Aqueous humor is secreted by the epithelium of the ciliary body, flows into the space in front of the iris, flows through the trabecular meshwork, and exits via the canal of Schlemm arrow). Blockade of the 13 adrenoceptors associated with the ciliary epithelium causes decreased secretion of aqueous. Blood vessels (not shown) in the sclera are also under autonomic control and influence aqueous drainage.
