3D Holographic Advertising Machine
3D holographic devices utilize holographic technology to create or display three-dimensional images. This technology can generate images in space, allowing viewers to see stereoscopic visuals without any auxiliary visual aids like 3D glasses. Holographic images can be observed from different angles, possessing realistic depth perception and parallax effects, making them appear as if real objects are suspended in the air.
Technical Principles
The holographic projection device does not utilize digital technology. Instead, it projects and stitches images from different angles onto a holographic film. This method ensures that viewers only see the image intended for their specific angle, thereby achieving genuine 3D holographic stereoscopic imaging.
Imaging Process
Step 01: Imaging Process
Firstly, the light wave information of the object is recorded using interference principles, which is the recording process. The object under laser irradiation forms a diffuse-type object light beam. Another part of the laser acts as a reference beam and is projected onto the holographic plate, overlapping with the object beam to create interference. This process converts the phase and amplitude of the object light wave at each point into varying intensities in space, capturing all the information of the object light wave using the contrast and spacing between interference fringes. After developing and fixing processes, the holographic plate becomes a hologram, also known as a holographic photograph.
Step 02: Imaging Process
The 3D holographic advertising machine is a novel advertising media device. It employs LED strip rotation display technology and the persistence of vision principle to display graphics, animations, and videos. Due to its lack of borders and backgrounds, it creates a visual sensation of images floating in mid-air. Changsha Yihong Information Technology Co., Ltd. leads in the independent research and manufacturing of 3D holographic screens and holographic visual systems, focusing on naked-eye 3D technology.
Application Scenarios
Currently, holographic advertising machines are primarily used in advertising media and exhibition fields. They can play 3D images and videos, embed WiFi modules for network connectivity, and feature realistic 3D video playback, long lifespan, low energy consumption, easy installation and use, high usability, and wide applicability. They are widely installed in indoor and semi-outdoor settings such as shopping malls, cinemas, hotels, restaurants, exhibition halls, specialty stores, subways, and airports.
Product Introduction
The appearance of a holographic advertising machine resembles that of a fan, consisting of two, four, six, or eight blades made up of LED light strips. The minimum spacing between blades is P0.18, and the maximum spacing is P0.78. When the holographic advertising machine rotates at high speed, it generates complete images. Because of its borderless and background-less design, users perceive the images as suspended in the air. It can be used bare or installed with stands for floor-standing or ceiling-mounted applications. The holographic advertising machine supports multi-unit splicing and adapts to all types of venues, including irregular splicing configurations. Compared to LED screens of similar size, holographic advertising machines are more cost-effective. Various styles and sizes of holographic advertising machines are available, offering customizable content playback and customizable outer casings such as circular, square, semi-circular, double-sided spherical, and more. There's always a model that suits your needs!
