What is a hologram?

Holographic technology is a technique that uses the principles of interference and diffraction to record and reproduce a true three-dimensional image of an object. Holography refers to the use of projection methods to record and reproduce all the information of the light emitted by an object. Holographic image The technology is commonly known as virtual imaging technology or holographic imaging. Its imaging principle is to record the phase and amplitude of the object's light wave through light wave interference, and at the same time, use the diffraction principle to display the object's light wave information, thereby achieving the imaging effect.

Since the advent of lasers in the 1960s, Holographic image the technology has developed rapidly. Holographic image It is a popular term for virtual imaging technology, also known as holographic imaging. Its basic imaging mechanism is to use light wave interference to simultaneously record the amplitude and phase of the object's light wave, and then use the diffraction principle to reproduce the object's light wave information. Holographic image The reproduced light wave information retains the amplitude and phase information of the original object's light wave, so the reproduced image has a strong three-dimensional effect. When people watch Holographic image it, they can obtain the same visual effect as watching the original object, including various positional parallax. Since the light information of each point on the object is recorded in the holographic image after imaging, in principle, any Holographic image part of it can reproduce part of the original object's image. If multiple exposure techniques are used, multiple images of the same object in different states can be recorded on the same film, and they can be displayed without interfering with each other. In addition, the Holographic image can be correspondingly enlarged or reduced.

Holographic image Advantages of:

1. The reconstructed three-dimensional image is conducive to preserving precious artistic materials.

2. When shooting, every point is recorded on the hologram, even if the photo is damaged, it does not matter.

3. The scene has a strong three-dimensional effect and is lifelike. With the help of a laser, it can be displayed at various exhibitions.
