How to Make a Hologram

INTEGRAF--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. 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.

pointpusher 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:

Aris Kolokontes art. Holography Two photographs of a single hologram taken from different viewpoints The holographic recording itself is not an image; it consists of an apparently random structure of either varying intensity, density or profile. 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

Synapse for Kinect SYNAPSE for Kinect Update: There’s some newer Kinect hardware out there, “Kinect for Windows”. This hardware is slightly different, and doesn’t work with Synapse. Be careful when purchasing, Synapse only supports “Kinect for Xbox”. Carnegie Mellon University - CMU Graphics Lab - motion capture library
