Holography

Overview and history[edit] The Hungarian-British physicist Dennis Gabor (in Hungarian: Gábor Dénes),[1][2] was awarded the Nobel Prize in Physics in 1971 "for his invention and development of the holographic method".[3] His work, done in the late 1940s, built on pioneering work in the field of X-ray microscopy by other scientists including Mieczysław Wolfke in 1920 and WL Bragg in 1939.[4] The discovery was an unexpected result of research into improving electron microscopes at the British Thomson-Houston (BTH) Company in Rugby, England, and the company filed a patent in December 1947 (patent GB685286). Several types of holograms can be made. Holograms can also be used to store, retrieve, and process information optically.[18] How holography works[edit] Recording a hologram. How to Make Holograms. "Everything should be made as simple as possible, but not simpler” - Albert Einstein We attempt to follow this dictum so you can make holograms easily.

How to Make Holograms

The procedures we propose herein are as simple as it is physically possible. In the process, we make holography not only as simple as possible, but safer, less expensive, and more accessible to young people. Most of the essential items described in this article can be found in Integraf's holography kits or are available separately. The kits provide materials for you to make many kinds of holograms, including reflection holograms and transmission holograms. The figure below shows a Class IIIa diode laser with an output of 3 to 4 mW when operated by 3.0 v dc. An excellent support for such a small laser is a wooden clothespin, as shown below. The wooden clothespin offers another advantage. The “white light reflection hologram” is the simplest to make. 4.1 Supplies 4.2 Preparing the object It is not necessary to have a completely dark room. How to Make a Hologram. Edit Article Edited by Alecander, Ben Rubenstein, Nicole Willson, Krystle and 44 others It's easier to make a 3D hologram than you think.

How to Make a Hologram

In fact, each year thousands of hobbyists, students, and teachers make holograms at home and school. To make a hologram, you'll need some basic holography supplies and household items (budget about $100), a quiet and dark room, and about 30 minutes. Ad Steps 1Gather your holography supplies and household materials listed in the "Things You'll Need" section below. 14View your hologram after it is completely dried with a point source such as that from a projector, flashlight, spotlight, LED white light, or the sun.

Tips Realize that vibrations and microscopic movement of even 1 millionth of a meter can ruin a hologram. Warnings Carefully read and follow all instructions for using your laser. Things You'll Need Holography SuppliesNote: Budget is around $100PFG-03M professional holographic film platesRed holography laser. Article Info. Desktop Helium Neon Laser Lamp Build. Here’s another fantastic tutorial from Jay, a DIY lasers expert. See all of our DIY laser projects. I’d like to show off my new desk top laser lamp! It’s a fairly simple project and makes for a nice display piece. Basically, this is a 10 inch tube with a gorgeous laser inside. I bought some basic materials and a project box from Radio Shack. I added some solid rods in the front just to add stability to the mount. You may also enjoy: احصاء. Com: Do more.
