Rachel Hahn Cheryl Blackwell Seminar November 2012 Optical Illusions An illusion is the distorted perception of a stimulus. They are not to be confused with hallucinations‚ which are false perceptions when there is no presence of a stimulus‚ in contrast‚ illusions are the misinterpretation of a true sensation (Illusion Wikipedia). Illusions are mundane phenomena‚ and are experienced by nearly everyone in similar ways where hallucinations are a personal experience and are typically limited

Making things look bigger When you use an optical instrument‚ whether it be something very simple like a magnifying glass‚ or more complicated like a telescope or microscope‚ you’re usually trying to make things look bigger so you can more easily see fine details. One thing to remember about this is that if you want to make things look bigger‚ you’re always going to use converging mirrors or lenses. Diverging mirrors or lenses always give smaller images. When using a converging lens‚ it’s helpful

efforts led to an elementary understanding of electroacoustic technology‚ resulting in the invention of the telephone. Time-division multiplexing Time Division Multiplexing (TDM) is a communications process that transmits two or more streaming digital signals over a common channel. In TDM‚ incoming signals are divided into equal fixed-length time slots. After multiplexing‚ these signals are

WHAT IS THE PRINCIPLES OF OPTICAL DEVICES‚NAME AND EXPLAIN FEW ! ANS:Storage and retrieval of data on optical disks can be described in two simple steps. First‚ data marks are recorded on a surface. Data marks can be prerecorded‚ like on a music CD‚ or they can be recorded by users on blank disks‚ like with CD-recordable products. The second step is retrieval of information from the disk‚ where a light beam scans the surface. Modulation in the reflected light is used to detect the data-mark

Analog to Digital When the conversion takes place between analog and digital it becomes the base of all communication technologies. Just about all hardware uses digital so it is very important to convert analog signals into digital to perform support for hardware applications. All hardware devices are aimed to be digital. Therefore‚ devices in the future will not need conversion because they will already be digital. There are many examples of analog to digital like a scan picture. The analog

ABSTRACT Title of Thesis: FREE-SPACE OPTICAL COMMUNICAITONS THROUGH A FOREST CANOPY Clinton Lee Edwards‚ Master of Science‚ 2004 Thesis Directed By: Professor Christopher C. Davis‚ Department of Electrical and Computer Engineering This paper models the effects of the leaves of mature broadleaf trees on air-to-ground free-space optical (FSO) communication systems operating through the leaf canopy. Ecological radiation transfer models are considered and the concept of Leaf Area Index

OPTICAL AMPLIFIER An optical amplifier is a device that amplifies an optical signal directly‚ without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity‚ or one in which feedback from the cavity is suppressed. Optical amplifiers are important in optical communication and laser physics. There are several different physical mechanisms that can be used to amplify a light signal‚ which correspond to the major types of optical

[pic] An optical illusion also called a visual illusion is characterized by visually perceived images that differ from objective reality. The information gathered by the eye is processed in the brain to give a percept that does not tally with a physical measurement of the stimulus source. There are three main types: literal optical illusions that create images that are different from the objects that make them‚ physiological ones that are the effects on the eyes and brain of excessive stimulation
