Principle and application of holographic technology

The principle and application of holographic technology: The first step is to record the information of the object light wave by using the interference principle, and the other part of the laser beam is superimposed with the object light beam as a reference beam to produce interference, thus converting the phase and amplitude of each point on the object light wave into the intensity that changes in space, and recording all the information of the object light wave by using the contrast and interval between interference fringes.

Features and advantages:

1. The reconstructed stereoscopic image is beneficial to the preservation and collection of precious artworks.

2. When shooting, every point is recorded on any point of the hologram, even if the photo is damaged, it doesn't matter much.

3. Holograms have strong stereoscopic impression and vivid images, and can be displayed in various exhibitions with the help of lasers, which will get very good results.

Holographic technology includes the future. Whoever uses this technology first will be the first to enter the ranks of advanced technologies in the future. Holographic projection technology is the reverse display of holographic technology, which essentially forms a three-dimensional image on air or a special three-dimensional lens. Unlike plane screen projection, which only realizes stereoscopic effect on two-dimensional surface through perspective and shadow, holographic projection technology is a real 3D image, which can view different sides of the image from any angle of 360.

The principle of holography is applicable to all kinds of waves, such as X-rays, microwaves, sound waves and electronic waves. As long as these waves have enough coherence in forming interference patterns.
