Ground interactive projection

Ordinary projection is the process of projecting a two-dimensional image onto a flat screen, where the viewer sees a flat image. Holographic projection can present real three-dimensional images, allowing viewers to observe different faces of objects from different angles, with a strong sense of three dimensionality and realism. In addition, ordinary projection usually only requires simple equipment such as projectors and screens, while holographic projection requires more complex optical systems and technologies to achieve.

Holographic projection has a wide range of applications in multiple fields. In the commercial field, it can be used for product display, advertising promotion, stage performances, etc., such as three-dimensional product display in shopping malls and virtual singer performances at concerts. In the field of education, it can be used for teaching demonstrations to help students understand complex scientific knowledge more intuitively. In the field of exhibition display, it can create an immersive exhibition experience and attract the attention of the audience.

Firstly, during the recording process, a reference light and an object light are simultaneously irradiated onto the object, causing interference between the two beams. The intensity and phase information of the object are recorded on the photosensitive material, forming a hologram. Then, during the reproduction process, the hologram is illuminated with the same beam of light as the reference light, and the hologram acts like a complex diffraction grating, causing the light to diffract and thus reproducing the three-dimensional image of the object.

One is the resolution and clarity of the image. To achieve high-resolution and high-definition 3D image reproduction, advanced optical equipment and algorithms are required. The second is the control of light interference and diffraction, which requires precise control of the propagation and interference conditions of light rays to ensure the stability and accuracy of the image. The third is the complexity and cost of the system. Holographic projection systems are usually quite complex, including optical components, light sources, control systems, etc., with high costs, which limits their widespread adoption.

Holographic projection is a technique that utilizes the principles of interference and diffraction to record and reproduce the true three-dimensional image of an object. It records the light information of an object on a hologram, and then uses a specific light source to illuminate the hologram, so that the three-dimensional image of the object can be presented in the air, and the audience can see the realistic stereoscopic image without wearing special glasses.
