Holography Holography has been around for sometime now, but has become increasingly more popular in recent years. Holograms are now found in virtually all types of products. These products consist of currencies, checks, stock certificates, credit cards, passports, ID cards, computer software, audio/visual tapes and CD ROMs, aircraft, software, electrical/electronic appliances, building materials, food, pharmaceuticals, cosmetics, food, building materials, branded fashion wear, tickets for
Excusive Summary The holography technology could record and display full information of three dimension objects by using interference and diffraction of light. It was invented in 1940s and develops to several types. For example, rainbow hologram is a wildly used technology on credit cards and currencies. Traditional hologram needs laser to reconstruct, but rainbow hologram only needs the white light, like sunshine. After this, people try to make hologram easier to reconstruct whereas the recording
HOLOGRAPHY Hologram and its Working Principle:- A hologram is a 3-dimensional (3D) image of an object. The first ever hologram was developed by Gober in 1947 before the laser light. That type of hologram is called in-line hologram as is almost abandoned in practical applications now. The working principles involved are interference and diffraction. Diffraction of light from an object is recorded and it is presented as a 3D image with the help of interference of this diffracted ray with a reflected
beam, the interference pattern created where the beams cross harbors a three dimensional image of the object . . . . The image will reappear when this 'hologram' is probed with a third beam of coherent light" (Glanz 736). Thus began the field of holography. Scientists first conceived of using Gabor's holograms to store data over thirty years ago. In 1962, IBM instructed Glenn Sincerbox to research using holograms to store data (Glanz 736). The scientists at the time felt, "The novel technology
I stepped through the doors of our energy efficient paperless school, one where students are encouraged to explore; it is focused around collaboration, gaming, virtual learning and 3D holographic technology, where all the surfaces are interactive and dynamic. The words came flowing; learning, feedback, group dynamics, e-portfolios, programmable and adjustable capsules...yes the day has began. Through ‘Berkeley’s world’ (BW) the game designed just for the school I got a request to show a visitor around
1. Problem definition 1.1. What is E-waste E-waste, or "Electronic waste", includes discarded computers, electronic equipments, entertainment consoles, mobile phones, televisions and many more. It comprises used electronics for reuse, resale, salvage, recycling, or disposal purposes. 1.2. Amount of E-waste Rapid changes in technology and falling prices have resulted in a fast-growing surplus of electronic waste around the globe. An estimate of 50 million tons of E-waste is produced each year (Sthiannopkao

(2-2) Fourier transform in two Dimensions The Fourier transform is a fundamental importance to image processing . It is a representation of an image as a sum of complex exponentials of varying magnitudes, frequencies, and phases . It plays a critical role in a broad range of image processing applications , including enhancement , analysis , restoration , and compression. Optics generally involves two-dimensional signals ; for example , the field across an aperture or the flux-density
Photography has become a part of our every day life, whether we notice it or not. Even though photography is not all that important to some, people should know about photography and it history. It lets us see beyond what our eyes can see and has changed the world. So how has photography changed the world? Photography has changed the world in many ways. Everyone knows the phrase, “A picture is worth a thousand words.” Images can bring the world pain, joy, sadness, and anger. If suddenly photography
"Light, electromagnetic radiation that can be detected by the human eye. "Within that broad spectrum the wavelengths visible to humans occupy a very narrow band, from about 700 nanometers (nm; billionths of a meter) for a red light down to about 400 nm for violet light. The spectral regions adjacent to the visible band are often referred to as light also, infrared at the one end and ultraviolet at the other (Stark)." Light spreads directly. Therefore light is unbending and moves linearly. Light
Lasers and Their Uses We have all at some point in our lives used or seen someone use a laser. They are used in compact disc players for stereos or computers, laser surgery, laser printers, holography, cutting and borring metals, communication, bar-code scanners, etc. Over the past three decades' lasers have become a tool used daily by many people and they have become very useful in scientific research. As you can see lasers are a very useful and important tool which is why I have chosen this topic
Holographic Universe In autumn of 1992, one of the world's greatest contemporary physicists passed away. David Bohm, whose work inspired many people all over the world, died in London. David Bohm's contributions to science and philosophy are profound, and they have yet to be fully recognized and integrated on the grand scale. David Bohm was born on December 20, 1917, in Wilkes-Barre, Pennsylvania. Bohm was fascinated by the dazzling concepts of cosmic forces and vast expanses of space that
What is optical art? Optical Art is a form of abstract art that gives the impression of movement with the use of pattern and color or with conflicting patterns that emerge and overlap. Sometimes an artist will include hidden images, flashing and vibrating patterns, swelling or warping. There are many optical artists out there, what makes them stand out the most is their approach to the concept. One of the most famous optical artists is Bridget Riley. Bridget Riley is an English painter who was
In the following, I will present the hypothetical case of Superman vs. Lex Luthor; it is wrong for Superman to prevent Lex Luthor from obtaining his goal of world domination. Luthor is a villain, his actions are “evil,” which is the reason Superman and Luther are in conflict; but Luthor believes that “the ends justify the means” meaning although his actions are disagreeable, his end goal is to better humanity as a whole. I will then analyses the case according to three ethical theories, namely Aristotle
“Too often we measure everything and understand nothing.” according to Jack Welch. So the government has decided to take a closer look at high powered Micro waves. In his paper I‘m going to speak to you about high power microwaves, it’s applications, a comparison of two different types, some of the history, and the findings in results of its research. “High power microwaves (HPM) is an imprecise term used by several communities [1]. In the DoD it pertains primarily to the generation of high peak
Self Portrait, 2007 by Chuck Close The artwork that ignited my interest at the High Museum of Art was the Self Portrait, 2007 by Chuck Close. In this particular painting, Close was influenced by a printing technique used in Japan known as nishiki-e. The nishiki-e technique involves multicolored wooden block printings, which would have a specific engraving on it and then arranged in a particular way to make an image. Close liked to experiment and combine different styles and techniques such as
Birth of the Universe Your universe, as we have suggested many times, as we've suggested already this morning, is but one universe among many. It is relatively a small universe — not to suggest that you should feel badly … {laughter} … for despite the consensus reality that bigger is better, despite the male-dominating energy and the comparative energies that say "bigger is better," your universe, though relatively small, is not at all diminished by its size. Now we know the word universe by
Salvador Dali, the Painter 1904-1989 Salvador Dali was born on May 11, 1904 in Figueras, northern Catalonia, Spain. His father, Salvador Dali y Cusi, a state notary, was a dictatorial and passionate man. He was also fairly liberal minded, due to a short but intense period of renaissance, and he accepted his son's occupation as a painter without much resistance to the idea. Salvador Dali exhibited many signs of marginality throughout his early years. Once Dali decided to become a painter, he concentrated
There are many ways to tell a story. Back before there were books there as the actual storyteller who could speak out a story. There is also acting where people physically perform a story. Books are another storytelling device that is more permanent, the words are kept and they can be reviewed again and again. Now there are movies, which provide story telling with more an emphasis on visual effects. The question is which way is the best to present a certain type of story. The Ice Storm by Rick Moody
