lenticulation

The term "lenticular" describes something that has the shape of a double-convex lens or is related to a lens. In photography, "lenticules" are minute lenses found on the base side of a film, used in stereoscopic or color photography.12

Lenticular technology is employed in creating three-dimensional images. By splitting a scene into narrow vertical strips from two viewpoints (similar to how human eyes perceive depth) and interlacing them, a lenticular grid can be superimposed. This allows the left eye to see the left-eye image strips and the right eye to see the right-eye image strips, creating a stereoscopic effect. These parallax stereograms are often seen in displays and can be reproduced in print with a lenticular pattern overlay. This technique is also utilized in photogrammetry for measuring objects and creating detailed maps.3
