A lenticular sheet is a flat piece of plastic or other material that has long ridges that lens light going through.
There are two types: 1D and 2D. 1D is the normal type. 2D lets you see light fields, also known as integral images.
A particular application of 2D lenticular sheets is integral photography (the purpose of which is to allow users to see 3D images), where two perpendicularly placed lenticular sheets can be used as a cheaper alternative to a fly-eye lens.[1] Two orthogonally stacked lenticular lenses work as if they were a single fly’s eye lens.[2]
They are measured in LPI (lenses per inch)
It can be in 8.5 by 11 form factor.
They were popularized by Vari-Vue.
