Main Imaging Module: The physical resolution shall be no less than 1920×1920; the imaging ratio is 1:1; the imaging contrast ratio is no less than 1000:1.

Holographic Imaging Module: 360° holographic. The light transmittance of the holographic imaging area shall be no less than 65%, and the reflectivity shall be no less than 30%; the overall holographic image shall be visible under normal daylight illumination; the holographic imaging can be viewed simultaneously from all sides, and the maximum viewing angle on a single side shall be no less than 140°.

Function Overview: The volume of the holographic imaging area shall be no less than 500mm×500mm×250mm; it supports group learning. The four sets of touch screens should be integrally connected with the teaching system. Each group of students participating in interactive learning can independently operate the teaching software through the interactive touch screen without interference. The system should also have room for upgrading and can expand network expansion capabilities such as remote centralized control or mobile terminal control. The video playback controlled by the teacher's end can be synchronized to the multimedia terminal devices to realize the linkage between the multimedia terminal devices and the holographic devices.
