Various 3 Dimension Image Techniques receive more and more attention in fields such as information, display, medical treatment, military affairs.Utilize lenticule Technology realizes three-dimensional imaging, has unusual potentiality and prospect.It is the integrated photography proposed in 1908 by G.Lippman Art develops.One group of two-dimensional cell image with three-dimensional scenic difference perspective relation is remembered by a lens arra and image acquisition Record, it is not necessary to special observation glasses and illumination, it is possible to observe directly the three of original scene in the front of display microlens array Dimension image.Universal along with the development of microlens array manufacturing process and high-resolution printing and imageing sensor, integration imaging skill Art has attracted the properties of increasing concern, integration imaging and Display Technique, the such as depth of field, visual angle and resolution etc., Have also been obtained bigger lifting.

In recent years, in terms of integration imaging imaging suspension optical thin film exploitation, there are the two noticeable progress of class: the first kind is individual Property Three-Dimensional Dynamic aerial image is write comments on a document, as Minnesota Mining and Manufacturing Company Douglas Dunn etc. (Personalized, Three-Dimensional Floating Images for ID Documents) in article and follow-up (Three-Dimensional Floating Images as Overt Security Features. SPIE-IS&T/Vol.607560750G-10) article proposes use the lens (NA > 0.3) of large-numerical aperture to make laser beam converge Gathering surface before or after microlens array, this convergent point collects record laser recording under microlens array by microlens array On material, change the relative position between laser beam focus points and microlens array and form figure, ultimately form Three-Dimensional Dynamic space The special visual effect of imaging, observes sample from microlens array side.The method needs to utilize lenticule imaging, to backing material Ablation, therefore resolution is relatively low.Equations of The Second Kind is based on More's imaging technique, and it utilizes the focussing force of microlens array by micro-figure Case is amplified expeditiously, it is achieved has certain depth of field and presents the pattern of peculiar dynamic effect, american documentation literature US7333268B2, Chinese patent literature 201080035671.1 disclose one and are applied to the marketable securities opened window safety lines such as banknote Microlens array safety element, its basic structure is: the upper surface at transparent base layer arranges preiodic type microlens array, The lower surface of transparent base layer arranges the micro-pattern array of preiodic type of correspondence, micro-pattern array be positioned at the focal plane of microlens array or its Near, micro-pattern array is roughly the same with microlens array arrangement, is zoomed into the More of micro-pattern array by microlens array Picture;The optical imaging film being made up of transmission focusing unit, its thickness is generally higher than three times of lenticule radius of curvature.Therefore, In order to reduce film thickness, it is necessary to use small-bore lenticule unit.Such as, bank-note paper safety line thickness is necessarily less than 50 Micron, therefore the diameter of lenticule unit is also necessarily less than 50 microns.Less lenticule unit limits the size of micro-pattern, Limit the design space of micro-pattern.

In order to overcome above-mentioned limitation, Chinese patent literature CN104118236A, CN201310229569.0, CN201410327932.7 proposes a kind of micro-focusing element array optical anti-counterfeit element and valuables.They use preiodic type micro- Focusing element array, film thickness can be reduced to the radius of curvature of micro-concentrating element, still obtain putting of preiodic type by it Big picture and text structure.When left and right or when tilting forward and back this imaging thin film, the image of the multiple amplification picture and text structures having other enters Enter viewing area.Chinese patent literature ZL201010180251.4 proposes a kind of optical anti-counterfeit element and uses this Security element Product.It is based on transmissive operation pattern, and the lenticular centre coordinate of each transmission-type in transmission-type micro-lens arrays layer is micro- Random distribution in lens array layer, the lenticule in micro-lens arrays layer is arranged with the micro-picture and text one_to_one corresponding in micro-picture and text layer.Should The structure mentioned in patent has three defects: one, owing to using transmission-type microlens array, micro-focusing unit layer, transparent The gross thickness of wall and picture and text structure sheaf will be greater than the bore of micro-concentrating element;Two is not limit to be positioned at base material first surface Microlens array and the position coordinates relation of micro-picture and text array, from the principles of science, under many circumstances, this structure will not Moir é pattern can be produced.Three be element use time, people from lenticule elementary layer unilateral observation to amplify micro-picture-text image, when When surface microlens array is covered by transparent foreign objects such as water, focusing lenslet will no longer play a role, and has the biggest in actual use Inconvenience.

In many situations, it is desirable to acquisition and there is stereo suspending effect, unique image.It is therefore proposed that new scheme, Unique 3D visual effect is provided, is not affected by observation visual angle, by the eyeball of people more can be attracted, make people obtain one Planting the shock effect of vision, and be easy to observation, the weatherability strengthening device is extremely necessary.

At present, imaging thin film of the prior art mainly includes substrate layer 10, microlens layer 11 and the patterned layer of outwardly convex 12, as shown in Figure 1.Wherein, microlens layer 11 and patterned layer 12 lay respectively at the upper and lower surface of substrate layer 10.
