The present invention relates to the technical field of display devices, in particular to an optical imaging structure, including: an optical imaging component, including a frame, a display screen, a light-emitting element, optical glass and a mirror surface, the optical glass is fixedly installed on one side of the frame, and the mirror surface is fixedly installed on the frame On the other side, several light-emitting elements are fixedly installed on the inner wall of the frame; the present invention presents an infinitely extended tunnel vision through repeated reflection between the mirror surface and the optical glass, and the image displayed on the display screen is in the middle of the infinitely extended tunnel Floating display, the image and the subsequent tunnel space form a visual distance difference, showing the visual effect of floating imaging. Through the detection of the viewer's position and data algorithm processing by the eye tracking device and holographic processing platform, the holographic image can be adjusted in time. The display angle enables the viewer to always observe the image angle of the correct perspective relationship, combined with the visual effect of floating imaging, so as to realize the visual effect of naked-eye 3D floating imaging.
