Analysis of the Columnar Lens Grating Used for Auto-Stereoscopic Three Dimensional Printing with Different Sizes

Columnar lens grating is the most frequently-used grating in modern auto-stereoscopic three dimensional (3D) printing. It has a very important impact on the auto-stereoscopic 3D presswork. Micro-analysis about columnar lens grating of auto-stereoscopic 3d presswork with different sizes is given in this work. The formula is obtained in which micro-parameters of the columnar lens grating come into contact. A practical analysis about the columnar lens grating used for auto-stereoscopic 3D presswork with same visual effect but different sizes is given with the aid of a scanning electron microscope (SEM). Moreover, the reason for different sizes of columnar lens grating used for auto-stereoscopic 3D presswork is presented, and the formula is proved practical by practical analysis. Various microcosmic parameters of columnar lens grating will be suitable for different sizes of the auto-stereoscopic 3D presswork.
