Embodiment Construction
[0021] Such as image 3 As shown, a volumetric three-dimensional display device based on circular screen scanning includes a high-speed projection device 1, a screen rotation transmission device 2, a screen group, a rotation speed detection device 3, a central control module 4 and a PC 5, and the screen The group includes a plurality of screens 6, and the plurality of screens 6 are fixedly installed on the screen rotating transmission device 2. The upper horizontal section of the screen rotating transmission device 2 is an imaging space 7, and the high-speed projection device 1 is located directly in front of the imaging space 7. The distance between two screens 6 requires that when one screen 6 is located in the imaging space 7, the rest of the screens will not block the imaging optical path of the imaging space 7, and the rotating speed detection device 3 is installed on the screen rotation transmission device 2, and the detection screen rotation transmission device 2, the P...
