lenticular lenses seminar ppt
A lenticular lens is an array of magnifying lenses, designed so that when viewed from slightly different angles, different images are magnified. 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.
LENTICULAR LENSES
Lenticular lenses are plastic lenses consisting of an array of optical elements (lenticules). When viewed from different angles, different areas under the lens are magnified.
UNDERSTANDING PITCH
Pitch is the count of lenticules per inch in a certain lenticular lens, measured in LPI. A lenticule is a single optical element, a vertical strip in the lenticular sheet.
LENTICULAR IMAGES
Lenticular images are specially prepared images to which the lens is attached. Views are arranged under lenticules so that each eye is projected a different view. The brain then integrates these views into a single coherent 3D image.
UNDERSTANDING INTERLACING
Interlacing is the process of creating a lenticular image from a set of 2D images. A small strip is taken from each 2D image and is combined in one image to match a specific lens pitch.
LENTICULAR LENS DURABILITY
The lenticular lens is manufactured from various types of plastic (PETG, PVC, Acrylic). The lens's ability to withstand extreme weather depends on the type of plastic from which it is made. Its resistance to vandalism, scratches, breakage and fire is determined by the plastic used.
PURCHASING LENTICULAR LENS
There are several lenticular manufacturers around the world. HumanEyes has secured special pricing for its customers with some of them.
For more information, please contact HumanEyes at 3d[at]humaneyes.com.
SIZES OF LENTICULAR SHEETS
There are standard sizes for lenticular sheets; however, for larger orders, manufacturers may be willing to cut the sheets to a certain size.
STORAGE OF LENSES
To avoid any shrinking or expanding of the plastic due to humidity or temperature changes, lenses should be stored in a controlled environment.
