Press, with the rapid development of science and technology, the projection of images is not only 2D technology, but also the projection technology of 3D images. Among them, holography (English: Holography), also known as holographic projection, holographic 3D, is more A photographic technique that records all the information (amplitude, phase) in the light waves reflected (or transmitted) by the object, and the light reflected or transmitted by the object can be completely reconstructed through the recording film, as if the object were there. By observing photos from different orientations and angles, you can see different angles of the object being photographed, so the recorded images can produce stereoscopic vision.

Of course, when holographic projection is used to project portraits or human-shaped standing cards, traditional projection tripods are currently used, and the wide screen is installed horizontally (16:9 width and height), so it is not convenient to project portraits or human-shaped standing cards. of upright feet are available. Traditionally, if it is installed in the horizontal direction of the wide screen (16:9), when displaying portraits, only the resolution of the short side can be used, that is, when 1920x1080, the portrait resolution height is only 1080, not 1920, and the left and right sides of the screen are at the same time. The resolution is also a lot of waste.
