What equipment is needed to realize holographic projection?
Holographic projection equipment includes: holographic projector, holographic projection screen, holographic projection film, holographic projection content production, etc. Holographic projection is divided into 180 degree holographic projection and 360 degree holographic projection and phantom imaging.

Holographic technology can be subdivided into optical holography, digital holography, computer holography, microwave holography, reflection holography, acoustic holography and so on. Used in display, measurement, encryption, identification and other fields, our common traditional holographic technology is optical holographic technology.

Holographic projection technology is a popular high-tech technology in recent years. Using holographic film with projection and image content to display products is a sales promotion method. It provides magical holographic images, which can be imaged on glass or acrylic materials.

This brand-new interactive display technology combines decoration and practicality, is completely transparent when there is no image, gives users a brand-new interactive feeling, and becomes the most fashionable product display and marketing means.

Principle of holographic projection technology;

Using the principle of interference to record the light wave information of the object, this is the shooting process: the photographed object forms a diffuser beam under laser irradiation; The other part of the laser beam is used as the reference beam of the holographic negative, which interferes with the object beam.

The phase and amplitude of each point on the object light wave are converted into intensity that varies in space, so that all information of the object light wave can be recorded by using the contrast and interval between interference fringes. Negative recording interference fringes become holograms, or holograms, after being developed and fixed.

It is an imaging process to reproduce the light wave information of an object by using the diffraction principle: a hologram is like a complex grating. Under the irradiation of coherent laser, the diffracted light wave of linearly recorded sine hologram can generally give two images, namely the original image (also called the initial image) and the * * * yoke image. The reproduced image has strong stereoscopic effect and real visual effect.

Every part of the hologram records the light information of every point on the object, so in principle, every part of the hologram can reproduce the whole image of the original object. Through multiple exposures, multiple different images can be recorded on the same negative, and they can be displayed separately without interference.
