A thin hologram [1]: Section 4.1 is one where the thickness of the recording medium is much less than the spacing of the interference fringes which make up the holographic recording. The thickness of a thin hologram can be down to 60 nm by using a topological insulator material Sb 2 Te 3 thin film. [9]
Billing itself as the world’s “first holographic communications platform,” US startup Proto is beaming life-size, “3D” video into universities, hotels and medical centers.
In general usage, a hologram is a recording of any type of wavefront in the form of an interference pattern. It can be created by capturing light from a real scene, or it can be generated by a computer, in which case it is known as a computer-generated hologram, which can show virtual objects or scenes.
Computer-generated holography (CGH) is a technique that uses computer algorithms to generate holograms.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.

Ordinary holograms are three-dimensional images encoded in a two-dimensional surface, such as the hologram on a typical credit card. "This time, the entire universe is encoded," he said.
You can now turn your old smartphone into a hologram because the future
Since its introduction, vibrometry by holographic interferometry has become commonplace. Powell and Stetson have shown that the fringes of the time-averaged hologram of a vibrating object correspond to the zeros of the Bessel function (), where (,) is the modulation depth of the phase modulation of the optical field at , on the object.

Government scientists working out of trailer in Illinois are testing out the hypothesis that we're all living in a holographic world. Yes, that means that Albert Einstein may not have been totally ...
