What is holographic projection technology?

Nowadays, Holographic projection technology is used in many exhibitions or science museums. Holographic projection technology is a popular high-tech technology in recent years. 3D Images are presented to the audience, breaking the barrier between the virtual world and the real world. People can feel the impact of real images anytime, anywhere. Many people don't understand what holographic projection technology is.

What is Holographic projection technology? Holographic projection technology, also known as virtual imaging technology, is a technology that uses the principles of interference and diffraction to record and reproduce the true three-dimensional image of an object. Each part of the hologram records the optical information of each point on the object. Therefore, in principle, each part of the hologram can reproduce the entire image of the original, and multiple different images can be recorded on the same film through multiple exposures, and these images can be displayed separately without interference.

Holographic projection technology can not only produce three-dimensional illusions in the air, but also allow the illusions to interact with the performers to complete the performance together, producing a shocking performance effect. In our lives, holographic projection technology is becoming more and more widely used, and many large shopping malls have specially established holographic projection areas. According to the environment's scenery, design corresponding animation effects, so that the environment and the projection picture echo each other, creating a visual impact and stunning feeling.

Holographic technology is a promotional method that uses a holographic film with projection and adds image content to display products. It provides magical holographic images that can be imaged on glass or acrylic materials. It combines decoration and practicality. When there is no image, it is completely transparent, giving users a brand-new interactive experience. Holographic projection equipment includes: holographic projector, holographic projection screen, holographic projection film, holographic projection content production, etc.

Holographic projection Technical principle:

1. Using the principle of interference to record the light wave information of the object, that is, the shooting process. The subject forms a diffuse object light beam under laser irradiation. Another part of the laser is used as a reference light beam and is projected onto the holographic film, superimposed with the object light beam to produce interference, converting the phase and amplitude of each point on the object light wave into spatially varying intensity. Using the contrast and spacing between interference fringes, all information of the object light wave can be recorded.

2. Using the principle of diffraction to reproduce the light wave information of the object, that is, the imaging process. A hologram is like a complex grating. Under the irradiation of coherent laser, the diffraction light wave of the sinusoidal hologram can give two images, namely the original image and the conjugate image. The reproduced image has a strong three-dimensional effect and a realistic visual effect.

These technological innovations not only break the traditional static exhibition promotion methods but also provide visitors with an interactive and interesting viewing mode. At the same time, they have also pushed the projection technology and application development to a new peak, showing us a different multimedia interactive experience.
