Holographic technology is a technology that records and reproduces the real three-dimensional image of an object by using interference and diffraction principle. It uses laser as illumination source, divides the light emitted by the source into two beams, superimposes interference on the photosensitive plate, and finally reproduces the hologram by using the basic principle of digital image.

1. Holographic technique is a technique that records and reproduces the real three-dimensional image of an object by using interference and diffraction principles.

2. Holographic photography uses laser as illumination source, and divides the light emitted by the light source into two beams, one beam directed to the photosensitive film, and the other beam reflected by the object and then directed to the photosensitive film.

3. Two beams of light superimpose on the photosensitive plate to produce interference. Finally, the hologram reconstructed by the basic principle of digital image is further processed to remove the digital interference and obtain a clear hologram.

4. At present, the main application places of holographic imaging technology are commercial exhibition, stage performance, entertainment, art, education, media science, technology design and so on. In terms of its stage application, holographic imaging technology can not only produce three-dimensional aerial illusion, but also make the illusion interact with performers to complete the table together. Performing, produces a shocking performance effect.
