Background
A hologram image is a three-dimensional image formed by recording a subject on a high-resolution hologram film using a panoramic camera with a laser light source.

At present, there are various methods for obtaining stereoscopic effect, and the most used technology is lenticular lens technology, which is also called lenticular lens or micro-lenticular lens 3D technology, and the most advantage is that the brightness is not affected. The principle of the lenticular technology is to add a layer of lenticular lenses in front of the display screen so that the image plane of the display screen is at the focal plane of the lenses, so that the pixels of the image under each lenticular lens are divided into several sub-pixels, and the lenses can project each sub-pixel in a different direction.
