Holographic projection is a Nolid 3D technology without glasses, and the audience can see three-dimensional virtual characters. This technology is widely used in some museums. Holographic stereoscopic projection equipment is not realized by digital technology, but the projection equipment projects images from different angles onto imported MP holographic projection film, so that you can't see other images that don't belong to your own angle, thus realizing real holographic stereoscopic images. 360-degree phantom imaging system: 360-degree phantom imaging is a kind of mid-air imaging that suspends three-dimensional images in real life, creating an illusory and real atmosphere, with peculiar effect, strong sense of depth and hard to distinguish between true and false. In the middle of the illusion in the air, we can combine objects to realize the combination of images and objects. It can also be equipped with a touch screen to realize interaction with the audience. According to the need, it can be made into four windows, each with a maximum size of 2-4 meters. Can be made into holographic phantom stage, product three-dimensional 360-degree demonstration; Real people and imaginary people perform on the same stage; Dream stage of science and technology museum. 3d holographic projection 3d holographic projection is suitable for individual items with rich details or internal structures, such as watches, famous cars, jewelry, industrial products, figures, comics and so on. Give the audience a completely three-dimensional feeling. Holographic interactive display system is the crystallization of nano-sensing touch film and scattering rear projection development technology. It is a novel and extraordinary way of displaying. Visitors can interact through the holographic display glass, giving visitors a mysterious and magical illusion, and providing a modern and fashionable interactive means for display and inquiry. When there is no image, the system is completely transparent and can be integrated with glass decoration. Under the specific software production method, the system can also provide a special image effect floating on the glass, giving customers a strong visual shock. At the same time, this exhibition can realize the control functions such as touching and selecting with fingers or other natural objects on the projection screen, opening the interface, changing the screen, querying information and dragging. Brand-new technology helps you break down the barrier between the virtual world and the real world. The appearance of a brand-new projection technology-holographic projection technology has enabled people to break this barrier and experience the unprecedented pleasure of visual impact. System Principle Holographic projection technology is a technology to record and reproduce the real three-dimensional image of an object by using the principles of interference and diffraction. The first step is to record the light wave information of the object by using the interference principle, which is the shooting process: the object to be photographed forms a diffuser beam under laser irradiation; The other part of the laser beam, as a reference beam, hits the holographic negative and interferes with the object light beam, converting the phase and amplitude of each point on the object light wave into spatially varying intensity, thus recording all the information of the object light wave by using the contrast and interval between interference fringes. After developing and fixing the negative recording interference fringes, it becomes a Norid hologram. The second step is to reproduce the light wave information of the object by using the diffraction principle, which is the imaging process: the hologram is like a complex grating. Under the irradiation of coherent laser, the diffracted light waves of linearly recorded sinusoidal holograms 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. [2] The 3D holographic projection system is a system that records and reproduces real 3D images of objects by using the principles of interference and diffraction. All-new things have changed people's aesthetic attitude towards those traditional stage sounds and photoelectric technology. Scope of application: product display, automobile and clothing conference, stage program, interaction, bar entertainment, interactive projection of places, etc.
