With the development of modern technology, the design of the exhibition hall is constantly innovating and upgrading. Among them, holographic cabinet and phantom imaging, as two advanced display technologies, have received extensive attention and application. However, many people don't really understand the difference between the two. This paper will make a detailed comparative analysis of the holographic cabinet and phantom imaging in the exhibition hall from the aspects of technical principles, application scenarios, and visual effects.
First of all, from the point of view of technical principles, there are obvious differences between holographic cabinets and phantom imaging. Holographic cabinet is a kind of holographic cabinet that uses the principle of laser interference to record the holographic image of the object, and then projects the holographic image onto the transparent holographic glass through the irradiation of the laser beam to form a three-dimensional virtual object. The audience can feel the three-dimensional effect of the object by observing the virtual object on the holographic glass. Phantom imaging is a kind of optical principle that uses optical principles to project the image of virtual objects onto a special screen through projection equipment, and then through optical reflection, the audience has an optical illusion, as if seeing the object suspended in the air.
Secondly, from the perspective of application scenarios, holographic cabinets and phantom imaging have their own characteristics. The holographic cabinet is suitable for displaying various three-dimensional items, such as cultural relics, artworks, commodities, etc. Since the holographic cabinet can present the three-dimensional form of the object, the audience can understand the details of the object more intuitively. In addition, the holographic cabinet can also realize interactive functions, and the audience can interact with virtual objects by touching the screen or gesture operation. Phantom imaging, on the other hand, is more suitable for displaying large-scale scenes, such as urban planning, landscape design, etc. Phantom imaging can project virtual scenes onto a huge screen, giving the audience an immersive experience. At the same time, phantom imaging can also achieve multi-angle**, allowing the audience to enjoy every detail of the virtual scene from different angles.
Moreover, from the visual point of view, the holographic cabinet and phantom imaging have their own characteristics. The visual effect of the holographic cabinet is more realistic, and the audience can observe the three-dimensional form of the object, and even see the texture and light and shadow effects of the object. In addition, the holographic cabinet can also realize dynamic display, and objects can be rotated, flipped and other actions on the holographic glass, which increases the interest of the display. The visual effects of phantom imaging are even more dreamy, and the virtual objects that the audience sees seem to float in the air, giving people a visual experience that transcends reality. Phantom imaging can also realize the combination of virtual and real, combining virtual objects with real scenes to create unique visual effects.
Finally, holographic cabinets and phantom imaging are also different from the cost and maintenance perspectives. The cost of holographic cabinets is relatively high, which is mainly reflected in the investment in holographic glass and laser equipment. In addition, the maintenance of the holographic cabinet is also more complicated, and the laser equipment needs to be regularly debugged and maintained. The cost of phantom imaging is relatively low, which is mainly reflected in the investment in projection equipment and screens. Maintenance of Phantom Imaging is relatively simple and requires only regular cleaning of the screen.
To sum up, there are obvious differences between the holographic cabinet and phantom imaging in the exhibition hall in terms of technical principles, application scenarios, visual effects, etc. The holographic cabinet is suitable for displaying three-dimensional items, with real visual effects and interactive functions;Phantom imaging, on the other hand, is suitable for displaying large-scale scenes, with dreamy visual effects and multi-angle features. When choosing a display technology, it should be considered comprehensively according to actual needs and budget.
