Specific embodiment
Figure 1 illustrates the partial cross section of the safety device 10 with transparent or translucent substrate 15, the substrate
15 have the first face 16 and the second face 17.The array of concentrating element is formed in the first face 16 in the form of Part-spherical lenticule 20
On, and the array of corresponding multiimage's element 30 is formed on the second face 17.
Concentrating element 20 can be formed directly in the surface in the first face 16 of substrate 15, it is preferable that being formed in for example
Applied by intaglio printing into the imprintable radiation curable ink in the first face 16.
Image component 30 can be the printing image component for for example applying the surface to the second face 17 by flexible version printing.
It is preferable, however, that image component is by imprintable radiation curable ink is applied to the second face 17, by embossment structure array
In being stamped into imprintable radiation curable ink and make ink solidification and the impressing image component that formed.
Fig. 2 is the partial cross section of the secure file 100 for including safety device 10.Secure file is included with the first face 106
With the transparent or translucent substrate 105 in the second face 107.Opaque ink 108, the layer of opaque ink 109 apply respectively
To the first face 106 and the second face 107 in addition to the window area residing for safety device 10.Preferably, in window area
Apply opaque ink 108,109 before forming safety device 10, to be easier to make safety device 10 be aligned with window area.
Referring now to Fig. 3, Fig. 4 and Fig. 8, the more details of safety device 10 are shown.By creating shakeization or half color
Tune into the melt the array of the generation of input picture 200 applying to the image component 30 in the second face 17 of device 10 of version.Shown in Fig. 8
In example, in each pixel-map to three brightness degrees of monochrome bit Figure 200, each brightness degree is corresponding to such as the right side
The rugosity of the specific line of the image component shown in the zoomed-in view in the region 211,212,213 of the image component array 210 of side
(amplitude modulation(PAM)).In the embodiment of alternative, (frequency modulation(PFM)) can be modulated according to the brightness degree of input picture 200 in base
The spatial distribution of the image component 30 on the second face of bottom 17, but amplitude modulation(PAM) is preferred.
Each image-region 211,212,213 includes pixel 25, pixel 25 be with overlapping part sphere lenses 20
The square area of the corresponding size of size.Pixel 25 will typically be the magnitude of 45 square microns to 65 square microns, but
It should be noted that greater or lesser size can be selected to be adapted to specific application.Will additionally appreciate, pixel is not necessarily square
, but select square pixel in numerous applications for convenience's sake.
Image-region 211 is a part of corresponding with the brightest area of input picture 200, and similarly includes producing maximum
The impressing image component 30 of the reflected light or transmitted light of amount, i.e., the rugosity with maximum line.Image-region 212 is located at image
In 200 time most bright part, and therefore compared with image component 30, the rugosity of the line of the image component 31 of image-region 212
It is slightly reduced.Similarly, the image-region 213 in the most black region of input picture 200 has the rugosity minimum of its line
Image component 32.
Image component 30,31,32 all has substantially the same shape, and the rugosity of only its line is different.Can be by line
Rugosity modulation to the process for being used to apply image component the degree that allowed of resolution.For flexible version printing, minimum point
Resolution is for about 7 microns.For moulding process, minimum resolution by for create impression block (master) electron beam or other
The resolution of process is limited, and can be nanometer scale.Because moulding process allows finer between the rugosity of line
Classification, and hence allow to finer brightness degree, seamlessly transit so as to produce between different colours or luminance area
Effect, so moulding process is preferred.
When the spacing of two arrays is slightly different or during rotatably misalignment, the array and image component 30 of lens 20,
Image component 31, the array of image component 32 can produce the image of More's amplification.Lens arra and cycle b for cycle a
Image component array amplification by a2/ Δ is given, wherein, Δ=a-b is pitch difference.If lens arra and pattern matrix
Cycle a it is identical, but its axis is each other in θ angles, then amplification be for about 1/ (1-cos θ).
3 × 3 grids of the pixel 25 in Fig. 3 include three image components 30,31 and 32.Each image component 30,31 or
32 is the non-diffraction unit of the impressing or printing surrounded by the region 35,36 or 37 of the surface relief structure including impressing respectively
Part.Surface relief structure in background area 35, background area 36 and background area 37 each other can have identical parameter (impressing
Depth, spatial frequency, curvature, azimuth), or if it is required, then surface relief parameter can change.
Will additionally appreciate, image component 30 can be formed to image component 32 by the non-embossed region of pixel 25,
That is, in addition to the region on the border of the shape with image component 30,31 or 32, whole pixel 25 is stamped.
Surface relief structure can be diffraction to produce its bright background area changed with viewing angle.Alternative
Ground, surface relief structure can be wavelet length (zero level) grating that particular color is respectively provided with all viewing angles.Advantageously, son
Wavelength structure generally also produces strong polarity effect, and thus changes the azimuth of the embossment structure (for example) between pixel
The further authentication feature that can be observed under polarisation filter can be caused.
Optical effect by produced by the device 10 of Fig. 1, Fig. 3, Fig. 4 and Fig. 8 is as follows.

At least one amplify and the single image element 30 of the version 130 of rotation, image component 31, image component 32.Although figure
Element 30, image component 31, image component 32 are incomplete same, but can be that the rugosity for making its line differs sufficiently small journey
Degree so that be single sampled images " average " by the collective effect produced by the single image element sampled by lens 20.
Image can also show as floating on or below the plane of device 10, and/or with causing device 10 to retreat by observer
Tiltedly and turn forward or tilt, picture showing goes out to show that positive parallax (orthoparallactic) is moved.If using spreading out
Penetrate background area 35, diffraction background area 36 and diffraction background area 37, then the image 130 for amplifying can also have bright color and
Optically-variable background.
When the second 17 finder 10 of face from substrate 15, single image element 30,31,32 is not exaggerated, and its
Size it is too little and can not by visually perceiving, (preferably 150 microns or less magnitude, even more preferably less than 70 microns, with
As for the viewing distance at 20 centimetres perceive less than), the common effect for producing monochromatic or colored image 200.
Therefore, when observing from first face 16 of transparent or translucent substrate 15, device 10 instead intuitively produces light
The image of floating that is variable, amplifying or motion is learned, and when observing from second face 17 of transparent or translucent substrate 15,
Device 10 produces immutable, tone the monochromatic or panchromatic image of optics.

Surface relief structure.Surface relief structure can have identical parameter (depth of impressing, space frequency in each image component
Rate, curvature, azimuth), or parameter can change from pixel to pixel or between the different rugosity of image component.When by saturating
When mirror 20 is observed, the embodiment of Fig. 5 and Fig. 6 produces at least one according to the color of the single image element being sampled and amplifies simultaneously
And the single image element 40,41,42 of the version 140 for rotating, which is also coloured.For Fig. 3 and 4, when from transparent or half
When second face 17 of transparent substrate 15 is observed, the device in Fig. 5 and Fig. 6 shows that optics as shown in Figure 8 is immutable, tone
Monochromatic or full-colour image.
