"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.

The late rap star's likeness was recreated in hologram form for the music festival with some impressive technology. YouTube to livestream Coachella music festival
Hereâ€™s another fantastic tutorial from Jay, a DIY lasers expert.
The word hologram comes from Greek, with holos meaning whole and graphe meaning writing. A hologram is an advanced form of photography that allows an image to be recorded in three dimensions, in fact a recording of an interference pattern made by the interaction of two beams of light.
Intended Use of Holograms Our holograms are designed, tested, and intended for anti-counterfeiting, anti-tampering and promotional applications. Our holographic products do NOT provide any documented health or medical benefits such as improved balance, sleep, pain-relief, weight loss, smoking cessation, etc. Our holographic products do NOT provide any documented benefits to improve gas mileage, energy efficiency, cell phone reception, etc. In our opinion, claims of medical benefits or improved machine performance are questionable and scientifically unsupported. Consumers should request an independent study (with blind testing) to verify any such claims and benefits.
Researchers at Tokyo University have come up with a technology that is a first and significant step away from the mouse and keyboard – touchable holograms.
