A hologram bracelet or energy bracelet [1] is a small rubber wristband supposedly fitted with a hologram. Manufacturers have said that the holograms supposedly "optimise the natural flow of energy around the body," and, "improve an athlete's strength, balance and flexibility". [ 2 ]
Holography has served as an inspiration for many video games with science fiction elements. In many titles, fictional holographic technology has been used to reflect real life misrepresentations of potential military use of holograms, such as the "mirage tanks" in Command & Conquer: Red Alert 2 that can disguise themselves as trees.

These systems have been used to produce holograms of live people. A holographic portrait of Dennis Gabor was produced in 1971 using a pulsed ruby laser. [1]: Figure 4.5, p44 [8] Thus, the laser power, recording medium sensitivity, recording time and mechanical and thermal stability requirements are all interlinked.
Just before the ball is struck, the hologram keeper initiates a dive, requiring the taker to follow through on the prescribed path, or quickly re-adjust and send the ball the other way.
The centerpiece of the system is a tamper-resistant security tape sticker with an embedded hologram. Each sticker carries a unique alphanumeric code. The sticker is affixed to all game-used merchandise and memorabilia, while information about the item is entered into a computer database. Between 500,000 and 600,000 items are authenticated each ...
Holographic optical element (HOE) is an optical component (mirror, lens, directional diffuser, etc.) that produces holographic images using principles of diffraction.HOE is most commonly used in transparent displays, 3D imaging, and certain scanning technologies.
It involves generating holographic interference patterns. A computer-generated hologram can be displayed on a dynamic holographic display, or it can be printed onto a mask or film using lithography. [1] When a hologram is printed onto a mask or film, it is then illuminated by a coherent light source to display the holographic images.
Dot matrix holograms also support covert laser readable (CLR) imagery, where a simple laser device may be used to verify the hologram's authenticity. Computing CLR images is a complicated mathematical task that involves solving ill-posed problems. [citation needed] There are two types of CLR: Dynamic CLR and Multigrade CLR. Dynamic CLR is a set ...
