A lenticular lens is an array of magnifying lenses, designed so that when viewed from slightly different angles, different images are magnified.^{[1][failed verification (See discussion.)]} The most common example is the lenses used in lenticular printing, where the technology is used to give an illusion of depth, or to make images that appear to change or move as the image is viewed from different angles.

Applications[edit]

Lenticular printing[edit]

Lenticular printing is a multi-step process consisting of creating a lenticular image from at least two existing images, and combining it with a lenticular lens. This process can be used to create various frames of animation (for a motion effect), offsetting the various layers at different increments (for a 3D effect), or simply to show a set of alternate images which may appear to transform into each other.

Israeli artist, Yaacov Agam uses lenticular printing as a key element in the construction of his kinetic art creations.

Corrective lenses[edit]

Lenticular lenses are sometimes used as corrective lenses for improving vision. A bifocal lens could be considered a simple example.

Lenticular eyeglass lenses have been employed to correct extreme hyperopia (farsightedness), a condition often created by cataract surgery when lens implants are not possible. To limit the great thickness and weight that such high-power lenses would otherwise require, all the power of the lens is concentrated in a small area in the center. In appearance, such a lens is often described as resembling a fried egg: a hemisphere atop a flat surface. The flat surface or 'carrier lens' has little or no power and is there merely to fill up the rest of the eyeglass frame and to hold or 'carry' the lenticular portion of the lens. This portion is typically 40 mm (1.6 in) in diameter but may be smaller, as little as 20 mm (0.79 in), in sufficiently high powers. These lenses are generally used for plus (hyperopic) corrections at about 12 diopters or higher. A similar sort of eyeglass lens is the myodisc, sometimes termed a minus lenticular lens, used for very high negative (myopic) corrections. More aesthetic aspheric lens designs are sometimes fitted.^[2] A film made of cylindrical lenses molded in a plastic substrate as shown in above picture, can be applied to the inside of standard glasses to correct for diplopia. The film is typically applied to the eye with the good muscle control of direction. Diplopia (also known as double vision) is typically caused by a sixth cranial nerve palsy that prevents full control of the muscles that control the direction the eye is pointed in. These films are defined in the number of degrees of correction that is needed where the higher the degree, the higher the directive correction that is needed.

Lenticular screens[edit]

Screens with a molded lenticular surface are frequently used with projection television systems. In this case, the purpose of the lenses is to focus more of the light into a horizontal beam and allow less of the light to escape above and below the plane of the viewer. In this way, the apparent brightness of the image is increased.

Ordinary front-projection screens can also be described as lenticular. In this case, rather than transparent lenses, the shapes formed are tiny curved reflectors.

3D television[edit]

As of 2010, a number of manufacturers were developing auto-stereoscopic high definition 3D televisions, using lenticular lens systems to avoid the need for special spectacles. One of these, Chinese manufacturer TCL, was selling a 42-inch (110 cm) LCD model—the TD-42F—in China for around US$20,000.^[3]

Lenticular color motion picture processes[edit]

Lenticular lenses were used in early color motion picture processes of the 1920s such as the Keller-Dorian system and Kodacolor. This enabled color pictures with the use of merely monochrome film stock.^[4]

Angle of view of a lenticular print[edit]

The angle of view of a lenticular print is the range of angles within which the observer can see the entire image. This is determined by the maximum angle at which a ray can leave the image through the correct lenticule.

Angle within the lens[edit]

The diagram at right shows in green the most extreme ray within the lenticular lens that will be refracted correctly by the lens. This ray leaves one edge of an image strip (at the lower right) and exits through the opposite edge of the corresponding lenticule.

Definitions[edit]

• ${\displaystyle R}$ is the angle between the extreme ray and the normal at the point where it exits the lens,
• ${\displaystyle p}$ is the pitch, or width of each lenticular cell,
• ${\displaystyle r}$ is the radius of curvature of the lenticule,
• ${\displaystyle e}$ is the thickness of the lenticular lens
• ${\displaystyle h}$ is the thickness of the substrate below the curved surface of the lens, and
• ${\displaystyle n}$ is the lens's index of refraction.

Calculation[edit]

${\displaystyle R=A-\arctan \left(\frac{p}{h}\right)}$,

where

${\displaystyle A=\arcsin \left(\frac{p}{2r}\right)}$,

${\displaystyle h=e-f}$ is the distance from the back of the grating to the edge of the lenticule, and

${\displaystyle f=r-\sqrt{r^2-{\left(\frac{p}{2}\right)}^2}}$.

Angle outside the lens[edit]

The angle outside the lens is given by refraction of the ray determined above. The full angle of observation ${\displaystyle O}$ is given by

${\displaystyle O=2(A-I)}$,

where ${\displaystyle I}$ is the angle between the extreme ray and the normal outside the lens. From Snell's Law,

${\displaystyle I=\arcsin \left(\frac{n\sin (R)}{n_a}\right)}$,

where ${\displaystyle n_a\approx 1.003}$ is the index of refraction of air.

Example[edit]

Consider a lenticular print that has lenses with 336.65 µm pitch, 190.5 µm radius of curvature, 457 µm thickness, and an index of refraction of 1.557. The full angle of observation ${\displaystyle O}$ would be 64.6°.

Rear focal plane of a lenticular network[edit]

The focal length of the lens is calculated from the lensmaker's equation, which in this case simplifies to:

${\displaystyle F=\frac{r}{n-1}}$,

3d Lenticular Art

where ${\displaystyle F}$ is the focal length of the lens.

The back focal plane is located at a distance ${\displaystyle BFD}$ from the back of the lens:

${\displaystyle BFD=F-\frac{e}{n}.}$

A negative BFD indicates that the focal plane lies inside Windows 8 pro product key. the lens.

In most cases, lenticular lenses are designed to have the rear focal plane coincide with the back plane of the lens. The condition for this coincidence is ${\displaystyle BFD=0}$, or

${\displaystyle e=\frac{nr}{n-1}.}$

This equation imposes a relation between the lens thickness ${\displaystyle e}$ and its radius of curvature ${\displaystyle r}$.

Example[edit]

The lenticular lens in the example above has focal length 342 µm and back focal distance 48 µm, indicating that the focal plane of the lens falls 48 micrometers behind the image printed on the back of the lens.

The only concern that remains with the sequence is the total number of images. The number of images needed to produce a lenticular image is the product of several factors. I mentioned earlier that 36 images is a number popular for high quality 3D lenticular prints. This is based on the popularity of piezo (Epson) printers in the lenticular industry that have a print head resolution different from that of thermal (HP) printers. The resolution of the printer and the resolution of the lenticular lens have a relationship that determines the best number of images for a sequence. The formula is DPI/LPI where the DPI is the actual print head resolution (not the stepper motor resolution) and the LPI is the fixed value of the lens. If you are printing this yourself determine the print head resolution of your printer and decide what lens you want to use. If the number of images in your sequence is not an exact number consider duplicating the end images if you are short a few, removing the end images if you have too many or using software like After Effects to “retime” the entire sequence to your final image count.
If you are having these printed elsewhere your service provider should be able to take your image sequence, whatever the total number, and adjust it for their workflow.
