Description

Technical Field

[0001] The utility model relates to the technical field of holographic imaging, and particularly relates to a holographic display system for a venue. Background Technique

[0002] Holographic imaging is a photographic method that can record and reproduce the three-dimensional (stereoscopic) image of an object without using a lens. It is a technology that can record the amplitude and phase information of the light wavefront from an object and can reproduce this light wave when needed.

[0003] When holographic imaging is displayed as holographic projection, light waves are a type of electromagnetic wave that carry amplitude and phase information during propagation. Ordinary photography uses a photosensitive material (such as a photographic film) as the recording medium and a lens imaging system (such as a camera) to form an image of an object on the photosensitive material. What it records is only the intensity distribution image of the light wave from the object, that is, the amplitude information, and does not include the phase information. Therefore, ordinary photography can only capture two-dimensional (plane) images. To record the amplitude and phase information of light waves simultaneously, a coherent reference light beam can be used, and the optical path difference between the object light and the reference light is used to determine the phase difference between the two light waves. Therefore, with the help of the reference light, the amplitude and phase information of the light wave from the object can be recorded.

[0004] Currently, the display of holographic imaging usually requires a large space, and holographic imaging is mainly used in conference venues where the space is limited. Moreover, in actual use, the equipment needs to be combined before it can be used, which is labor-consuming. Content of the Utility Model
