Diffraction grating Material
Born in the eighteenth century (Rittenhouse, 1786), the diffraction grating has been one of the most valuable instruments in the history of science and technology. At one extreme, it has enabled the study of celestial bodies. On the other hand, it has been a crucial tool in the study of atomic and molecular structures. These outstanding capabilities are the consequence of one basic…

Recommended Articles The arrival of these devices marks the first time that Microsoft has brought a new product to its hardware line since the Surface and Surface Pro back in 2012. However, we must not forget the mobile phones launched by Microsoft-owned Nokia, of course. “Holographic computing, enabled…

Uses of diffraction
Eventually the work of Scottish physicist James Clerk Maxwell (1831-1879), German physicist Heinrich Rudolf Hertz (1857-1894), and others confirmed that light did indeed travel in waves. Later, however, Albert Einstein (1879-1955) showed that light behaves both as a wave and, in certain circumstances…
Applications of diffraction Gratings
Examples of grating-based products designed and manufactured by Holographix include: Telecom applications require gratings with: very low polarization dependent loss (PDL) high diffraction efficiency high grating to grating repeatability insensitivity to extreme environmental conditions A telecom manufacturer of tunable wavelength products has determined through rigorous trials…

Scott hologram goggles
By Scott Corrales The following article appeared in the March 2003 edition of FATE Magazine. In the year 2002, the world’s attention was fixed upon Argentina. Alarmingly, hundreds of animals were dying mysteriously in different parts of that South American nation, and high-strangeness phenomena were also being reported. Gabriela and Griselda In August 2002, amid the confusion, a…

Reality hologram
Reality Reality is a consciousness program (hologram, simulation, illusion, dream) created by digital codes. Numbers, numeric codes, define our existence and experiences. Human DNA, our genetic memory, triggers (remembers) by digital codes at specific times and frequencies as we experience. Those codes awaken the mind to the change and evolution of consciousness. The brain is an…

Holographic smartphone
A Chinese company claims to have produced the world’s first smartphone with a holographic interface. It’s called the Estar Takee 1, and no, we’d never heard of the company before, either. To generate a holographic image, the Takee phone has four front-facing cameras, which track the user’s eyes to create a three-dimensional image. If that sounds familiar, it’s the same approach…

Wavelength order
Electromagnetic Waves have different wavelengths When you listen to the radio, watch TV, or cook dinner in a microwave oven, you are using electromagnetic waves. Radio waves, television waves, and microwaves are all types of electromagnetic waves. They differ from each other in wavelength. Wavelength is the distance between one wave crest to the next. Waves in the electromagnetic…

Types of Holography
What is a hologram? A hologram is a recording in a two- or three-dimensional medium of the interference pattern formed when a point source of light (the reference beam) of fixed wavelength encounters light of the same fixed wavelength arriving from an object (the object beam). When the hologram is illuminated by the reference beam alone, the diffraction pattern recreates the wave…
