It examines, and with the variation at visual angle, pattern can be relatively moved.It has distinctness relative to existing optics motion graphics
The characteristics of, pattern content is abundant, it can be achieved that the directions such as orthogonal, parallel move, and technology of preparing is more demanding etc..This structure can be used for
Commodity packaging and anti-counterfeit field.
In order to achieve the above objectives, it is proposed by the present invention it is a kind of based on microlens array and micrographics array can be along one party
To the preparation method of mobile motion graphics, specific steps include：
(1) preparation of microlens array；According to a preliminary estimate moir patterns amplification effect so that it is determined that lenticule period be D,
Lens rise is that h is prepared by rectangular arranged using the method for contact photolithography；
(2) preparation of micrographics array；Design micrographics array, period d, press rectangular arranged, micrographics array with
The angle theta of microlens array (horizontal direction) overlapping determines according to the following formula：
Wherein γ is motion graphics and horizontal direction angle, and D, d are respectively the period of microlens array and micrographics array,
θ is the angle of micrographics array and horizontal direction, the angle θ of micrographics array is calculated according to selected D, d and γ, and use
It is prepared by the method for contact photolithography；
(3) size of thickness is selected to be equal to the PE film or PVC film of the focal length of lens, on one side as the carrier of microlens array,
Another side and the PE film or PVC film that are printed on micrographics array is glued.
Beneficial effects of the present invention, there is provided a kind of novel figure move modes, enhance human visual experience, separately
On the one hand, design preparation has centainly technical, it is difficult to be imitated.
