Lenticular
Lenticular imaging uses an array of narrow cylindrical lenses to direct different parts of an interlaced image toward different viewing positions. The optical sheet is aligned with a picture or electronic panel containing thin strips from multiple source views.
Because each eye occupies a different position, the two eyes can receive different views and perceive stereoscopic depth. Moving sideways reveals additional views, allowing motion parallax, animation, or an image flip.
Traditional lenticular prints use a fixed interlaced image beneath a plastic lens sheet. Electronic lenticular displays combine a high-resolution panel, an optical layer, and software-generated interlacing. In both cases, the image pitch and optical pitch must be accurately aligned.
Common limitations include reduced resolution per view, a restricted viewing zone, crosstalk between views, sensitivity to alignment, and visible jumps when too few viewpoints are provided.
A lenticular lens sheet sends different image strips in different directions.
