3D Lenticular Sheet/Grating
3d lenticular sheet can show various different special effects on tailor-made film by combining digital technology and traditional printing technology. It can display vivid stereoscopic effect, showing animated fragments as in films and fantastic changing effects.
3d lenticular sheet is a slice made of lens. When we see from one side of the scene, we could see the image in a very thin line from the other side and the position of the line is determined by observing angles. When we observe from different angles, we could see different images.
According to the research, when we observe a 3d lenticular subject, as our eyes are seperate in two places, the images that we observe are different, there exists aberration. As it exists, we could feel the changing depth. This is the so-called stereoscopic visual theory. According to the theory, if we could make our left and right eye see different images, we could feel a depth space.
