3D holograms are a relatively recent and revolutionary technology that most people have only seen in Hollywood films. They've now become a reality in an imposing way. The disparity between what the eye sees and what the mind is aware of can result in an extraordinarily long attention span, which is a perfect way to embed product details or build a positive picture in people's minds. Although the eye sees what appears to be a tangible object or impact, such as fire, the brain recognizes that what it is seeing is not accurate. And it is precisely this effect that naturally induces a long attention span in the observer, resulting in up to 80% of people watching a 2–3-minute hologram from beginning to end – an effect that cannot be replicated with a traditional film projected on television.

Apart from that, a 3D hologram is highly appealing, making it ideal for presenting complex technical concepts and showcasing precious stones and other visually attractive objects. This technology allows you to highlight their elegance and perfection while still displaying them in a highly aesthetic manner, rendering the presentation a sensory experience.

The desk hologram fan is the smallest solo hologram display we made. The diameter is 314mm only. Because of the tiny size, it can be carried at any time, and it can be fixed on some device like bicycle or the bodies.

What is a hologram?

Ans: Holography is a technique that allows you to record and reconstruct a wavefront. Holography is best known for creating three-dimensional images, but it can also be used for various other things. Any form of wave can theoretically be turned into a hologram. A hologram (from the Greek for "complete definition" or "complete picture") is created by superimposing a second wavefront (usually called the reference beam) on the wavefront of interest, resulting in an interference pattern that is captured on a physical medium.

What is a hologram test?

Ans: Optical holography is an imaging technique that uses an interferometric pattern on film to record the amplitude and phase of light reflected from an object. As a result, the complete 3-D representation of the target can be reconstructed. The test sample is compared interferometrically in two separate stressed states in HNDT.
