Optical Computing Jainam Shah Kalol Institute Of Technology‚ Kalol‚ Gujarat‚ India. jainam_8888@yahoo.co.in Abstract—Optics has been used in computing for a number of years but the main emphasis has been and continues to be to link portions of computers‚ for communications‚ or more intrinsically in devices that have some optical application or component (optical pattern recognition‚ etc). Optical digital computers are still some years away‚ however a number of devices that can ultimately lead to

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

Green synthesis of metal nanoparticles using plants Siavash Iravani* Received 10th April 2011‚ Accepted 20th July 2011 DOI: 10.1039/c1gc15386b In recent years‚ the development of efficient green chemistry methods for synthesis of metal nanoparticles has become a major focus of researchers. They have investigated in order to find an eco-friendly technique for production of well-characterized nanoparticles. One of the most considered methods is production of metal nanoparticles using organisms. Among

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

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

[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

ABSTRACT: Silver nanoparticles are nanoparticles of silver which are in the range of 1 and 100 nm in size. Silver nanoparticles have unique properties which help in molecular diagnostics‚ in therapies‚ as well as in devices that are used in several medical procedures. The major methods used for silver nanoparticle synthesis are the physical and chemical methods. The problem with the chemical and physical methods is that the synthesis is expensive and can also have toxic substances absorbed onto
