Optica Glossary

3D (Effect)

The perception of depth as seen in a lenticular image. This effect involves layering multiple elements of an image into foreground, middle, and background planes. These elements are then shifted relative to one another to produce the appropriate parallax.

Animation (Effect)

This effect uses frames in the sequence of the action arranged in order of occurrence. This sequence can be short with only two images or longer sequences of motion and changing when walking past the lenticular image. Think of it as being 2 images in 1 space, but seen from different angles. It is also known as a “flip” image.

Combo (Effect)

A combination of various effects on one lenticular image—for example, 3D and Animation.

Lens

One of many tiny cylindrical or spherical lens segments formed on the surface of the film. The Micro Optical Material is a design array to produce the appropriate visual effect upon printing the back surface.

Lenticular

1) shaped like a lentil or a biconvex lens.
2) of the lens of the eye. [L lenticularis (as lentil)]1

Lenticular is a lens material that separates an image viewed on the rear surface of the lens into a binocular or sequence view that allows the viewer a depth or motion sensation.

Lenticular printing

An imaging process in which alternating strips of images are placed on the back of a transparent sheet with a series of curved ridges (lenticules), through which light is passed and through refraction and magnification makes a single complete image; as one changes the angle of the card in relation to one’s line of sight, one sees the different image strips as a series of complete images.2

Lenticules

One of many tiny cylindrical or spherical lens segments embossed on the surface of a film used in stereoscopic and color photography.3

LPI

Lens per inch.

Micro Optical Material

1) shaped like a semi-circular lens or a binocular lens.
2) of the lens of the eye. [L lenticularis (as lentil)]1

Optica™ is a superior material that separates an image viewed on the rear surface of the lens into a binocular or sequence view that allows the viewer a depth or motion sensation.

Morph (Effect)

This effect involves the gradual changing or transformation of one image into another using computer animation techniques. This is best achieved with similar shapes or objects.

Parallax

The apparent displacement of an observed object due to a change in the position of the observer.4

Pitch

Mechanical Pitch: The exact count or number of lenticules per inch (LPI).

Visual Pitch: The adjusted pitch value to account for optics and viewing distance.

Stereo Vision

Stereopsis or Stereoscopic Vision—A byproduct of good binocular vision; vision wherein the separate images from two eyes are successfully combined into one three-dimensional image in the brain.

Zoom (Effect)

This effect is a variation of the animation process involving gradually increasing the size of a single image to achieve a zoom effect. This gives the impression of the image moving closer to the viewer.
