![]() This shape dramatically improves the image quality. It was determined that the most viable cross-sectional shape for the lenticular lenses is elliptical. The objectives of this research effort were to develop a realistic analytical model, to significantly improve the image quality, to develop the tooling necessary to fabricate lenticular lens array extrusion cylinders, and to develop enhanced fabrication technology for the extrusion cylinder. ![]() This limitation causes the lenticular lens arrays to be generally thick (0.5 mm) and not easily wrapped around such items as cans or bottles. The principal limitation to the resultant image quality for current technology lenticular lenses is spherical aberration. The lenses comprise a front surface having a spherical cross- section and a flat rear surface upon where the material to be displayed is proximately located. The use of these typically cylindrical lens arrays for this purpose began in the late 1920's. ![]() In general, lenticular arrays can create from interlaced printed images such visual effects as 3-D, animation, flips, morph, zoom, or various combinations. Lenticular lens arrays are widely used in the printed display industry and in specialized applications of electronic displays.
