Definitions
- This invention relates to an improved form of optical security device for use in the protection of documents and articles of value from counterfeit and to verify authenticity. More specifically, this invention relates to an optical security device that provides enhanced design capability, improved visual impact, and greater resistance to manufacturing variations.
- Micro-optic film materials projecting synthetic images generally comprise: an arrangement of micro-sized image icons; an arrangement of focusing elements ⁇ e.g., microlenses, microreflectors); and optionally, a light-transmitting polymeric substrate.
- the image icon and focusing element arrangements are configured such that when the arrangement of image icons is viewed using the arrangement of focusing elements, one or more synthetic images are projected. These projected images may show a number of different optical effects.
- Such film materials may be used as security devices for authentication of banknotes, secure documents and products.
- these materials are typically used in the form of a strip, patch, or thread and can be either partially or completely embedded within the banknote or document, or applied to a surface thereof.
- ID identification
- these materials could be used as a full laminate or inlayed in a surface thereof.
- product packaging these materials are typically used in the form of a label, seal, or tape and are applied to a surface thereof.
- 7,738,175 which reveals a micro-optic system that embodies (a) an in-plane image having a boundary and an image area within the boundary that is carried on and visually lies in the plane of a substrate, (b) a control pattern of icons contained within the boundary of the in-plane image, and (c) an array of icon focusing elements.
- the icon focusing element array is positioned to form at least one synthetically magnified image of the control pattern of icons, the synthetically magnified image providing a limited field of view for viewing the in-plane image operating to modulate the appearance of the in-plane image. In other words, the appearance of the in-plane image visually appears and disappears, or turns on and off, depending upon the viewing angle of the system.
- optical security device which comprises:
- control patterns of icons contained on or within the at least one in-plane image forming an icon layer each control pattern being mapped to areas of the in-plane image having a range of grayscale levels, wherein placement of the control patterns of icons within the in-plane image is determined using one or more control pattern probability distributions associated with each grayscale level within all or part of the in-plane image,
- the array of icon focusing elements is positioned to form at least one synthetically magnified image of at least a portion of the icons in each coextensive control pattern of icons, the at least one synthetically magnified image (which intersects with the at least one in-plane image) having one or more dynamic effects, wherein the one or more dynamic effects of the at least one synthetically magnified image are controlled and choreographed by the control patterns of icons.
- the synthetically magnified images demonstrate dynamic optical effects in the form of, for example, dynamic bands of rolling color running through the in-plane image, growing concentric circles, rotating highlights, strobe-like effects, pulsing text, pulsing images, rolling parallel or non-parallel lines, rolling lines that move in opposite directions but at the same rate, rolling lines that move in opposition directions but at different or spatially varying rates, bars of color that spin around a central point like a fan, bars of color that radiate inward or outward from a fixed profile, embossed surfaces, engraved surfaces, as well as animation types of effects such as animated figures, moving text, moving symbols, animated abstract designs that are mathematical or organic in nature, etc.
- Dynamic optical effects also include those optical effects described in U.S. Patent No. 7,333,268 to Steenblik et al., U.S. Patent No. 7,468,842 to Steenblik et al., and U.S. Patent No. 7,738,175 to Steenblik et a/., all of which, as noted above, are fully incorporated by reference as if fully set forth herein.
- one or more layers of metallization cover an outer surface of the icon layer.
- the synthetically magnified image(s) of the in-plane image(s) is always On'.
- the device is tilted synthetically magnified images in the form of bands of color sweep over the surface of the in-plane image, revealing tremendous detail ⁇ i.e., improved visual impact).
- the bands of color are 'choreographed' using the multiple control patterns of icons.
- the 'ghost image' which is troublesome for the micro-optic system of U.S. Patent No. 7,738,175, helps the optical effects of the present invention to be more convincing by providing a silhouette of the in-plane image at every tilt angle that can always be seen.
- the in-plane image may be made much larger thereby providing enhanced design capability.
- the inventive device is less sensitive to manufacturing variations. While any such manufacturing variation may serve to change the angle and shape of the synthetic images, the relative choreography will remain the same, and thus the effect will not be disturbed to the same extent as the prior art system.

- the method for forming the icon layer in this exemplary embodiment comprises: selecting a sequence of grayscale in-plane images, selecting a set of control patterns of icons for each grayscale in-plane image; and using the grayscale in-plane images to drive placement of its respective control patterns of icons within the in-plane image to together form the icon layer.

- optical security device of the present invention By way of the optical security device of the present invention, a new platform for giving very detailed images is provided. As mentioned above, the inventive device provides enhanced design capability, improved visual impact, and greater resistance to manufacturing variations.
- the in-plane image of the inventive optical security device is an image that has some visual boundary, pattern, or structure that visually lies substantially in the plane of the substrate on which or in which the in-plane image is carried.
- grayscale in-plane image 10 in the form of a monkey's face is marked with reference numeral 10.
- Grayscale in-plane image 10 which is simply an image in which the only colors are shades of gray ⁇ i.e., shades from black to white), has a boundary 12 and an image area 14 within the boundary that, as noted above, visually lies substantially in a plane of a substrate on which the in-plane image 10 is carried.
- the grayscale image was made so that the parts that seem 'closest' to the viewer (the eyes and nose) are whitest, while the parts that seem 'farthest away' from the viewer are darkest.
- a single grayscale image (such as that shown in FIG. 1A) is chosen and scaled to the 'actual size' that it should be in physical form.
- the image is scaled to a size ranging from about several square millimeters to about several square centimeters. This is typically much larger than the focusing elements, which in terms of microlenses typically having a size on the order of microns or tens of microns.
- a tiling 16 is superimposed onto the grayscale image 10.
- This tiling 16 represents cells that will contain the control patterns of icons.
- the size of each cell is not limited, but in an exemplary embodiment, is on the order of the size of one or several focusing elements ⁇ e.g., from several microns to tens of microns). While rectangular- shaped cells are shown in FIG. 1 B, any variety of shapes that form a tessellation can be used ⁇ e.g., parallelograms, triangles, regular or non-regular hexagons, or squares).
- a numerical range is then selected to represent the colors black and white and the various levels of gray in between black and white.
- Some methods map black to 0 and white to 255, and the levels of gray to the integers in between ⁇ e.g., in 8-bit grayscale images), while some methods use larger ranges of numbers ⁇ e.g., in 16 or 32 bit grayscale images).
- 0 is used for black and 1 is used for white and the continuum of real numbers in between 0 and 1 is used to represent the various levels of gray.
- the level of grayscale at the location of each cell in the grayscale image 10 is then determined. For example, and as best shown in FIG. 2, for each cell, a common point is chosen ⁇ e.g., the lower-left corner of each rectangular tile or cell) and the level of grayscale of the in-plane image 10 corresponding to that point is measured at the common point and assigned to the cell. This can be achieved through direct measurement of the grayscale image at that point (as illustrated in FIG. 2), or the value can be interpolated from the pixels of the grayscale image using various image sampling techniques.
- the pixels of the grayscale in-plane image 10 are smaller than the cells of the tiling 16.
- the pixels of the grayscale in-plane image can be larger than the cells.
- Each cell is then assigned a number which represents the determined level of grayscale and which falls within the selected numerical range ⁇ e.g., 0-1 ). This assigned number is referred to as the cell's grayscale value.
- the coextensive control patterns of icons are contained on or within the in-plane image(s) forming an icon layer, with each control pattern containing icons mapped to areas of the in-plane image that fall within a range of grayscale levels ⁇ e.g., a grayscale level between 0 (black) and 0.1667).
- a control pattern probability distribution is specified, which serves to assign a range of random numbers to each control pattern.
- Each cell is then provided with a random number that falls with the selected numerical range ⁇ e.g., 0-1 ) using a RNG.
- control pattern probability distribution effectively sets the probability that a particular control pattern in the control pattern palette will be used to fill a particular cell.
- FIG. 3 An example of a control pattern distribution is shown in FIG. 3.
- three different control patterns are in the control pattern palette (Control Pattern A (CP A), Control Pattern B (CP B), Control Pattern C (CP C)), with each control pattern occupying its own triangular region in the control pattern distribution.
- Each possible grayscale value is mapped to a vertical cross section of this distribution. The vertical cross section showing which random numbers correspond to which control pattern.
- CP A Control Pattern A
- CP B Control Pattern B
- CP C Control Pattern C
- Each possible grayscale value is mapped to a vertical cross section of this distribution. The vertical cross section showing which random numbers correspond to which control pattern.
- the probability that Control Pattern A should be chosen is 100%
- the probability that Control Pattern B should be chosen is 0%
- the probability that Control Pattern C should be chosen is 0%. This is because all of the random numbers between 0 and 1 will correspond to control pattern A.
- control pattern probability distribution is simply a mathematical construct that connects a random number to the choice of control pattern.
- the control pattern distribution can adjust many different aspects of the dynamic optical effects of the subject invention, such as, for example, more rapid or slower transition between control patterns, and multiple control patterns visible simultaneously.
- different portions of the in-plane image may have different control pattern distributions and different collections or palettes of control patterns. This would allow some portions of the in-plane image to be activated with left-right tilting, while other portions are activated with towards-away tilting, and yet other portions to be activated regardless of the direction of tilt.
- the primary purpose of the control pattern distribution is to automatically 'dither' or smooth the boundaries between the parts of the grayscale image that would be filled with different control patterns of icons. Because the control pattern distribution provides a probabilistic means by which the control patterns of icons are chosen, the areas of the in-plane image that are assigned to a given control pattern need not be sharply defined. Instead, there can be smooth transition from one control pattern's area to the next. [0042] Sharp boundaries can, however, be made to exist through proper definition of the control pattern probability distribution. A control pattern distribution that would provide sharp transition from one control pattern to the next is shown in FIG. 4. Because there is no vertical overlap between the Control Pattern regions in this distribution, the random numbers essentially play no role in the selection of the control patterns.
- any grayscale value from 0.0 to 0.25 would result in that cell being filled with Control Pattern C
- any grayscale value from 0.25 to 0.7 would result in that cell being filled with Control Pattern B
- any grayscale value from 0.7 to 1.0 would result in that cell being filled with Control Pattern A.
- the next step in the inventive method for forming an icon layer of an optical security device is filling each cell with its determined control pattern of icons.
- the dynamic effects of the synthetically magnified images generated by the inventive optical security device are controlled and choreographed by the control patterns of icons. More specifically, the choreography of these images is prescribed by the relative phasing of the control patterns and by the control pattern distribution, in addition to the nature of the grayscale in-plane image.
- FIG. 5 a collection of six (6) control patterns, each made up of different gray-toned icons in the form of horizontal lines 18, is shown for illustrative purposes.
- the bold black outlines 20 represent the tile which would be used to repeat (tessellate) the control patterns of icons on a plane.
- the tiles for these six control patterns which define the manner in which the control patterns are tessellated onto a plane, happen to be the same rectangular shape.
- the tiles can adopt any shape that forms a tessellation.
- the tiles shown in FIG. 5 also have the same dimensions.
- the tiles are 'in phase' in the sense that they meet up along the same grid. This ensures that, when the control patterns are distributed on or within the in-plane image, the relative timing of when the control patterns are 'activated' remains constant.
- the icons in each control pattern are shifted relative to the icons in other control patterns.
- the icons may be very slightly shifted up by a few hundred nanometers or slightly more dramatically shifted by a few microns.
- the icons in each control pattern could be shifted left-right or right- left, while for control patterns of icons in the form of diagonal lines, the icons in each control pattern could be shifted along the diagonal.
- the control patterns could have an intentionally coordinated 'starting point' and fall along different grids.
- control patterns While six (6) control patterns are shown in FIGS. 5 and 6, the number of control patterns used in the present invention is not so limited. In fact, the number of control patterns of icons could be of infinite number and variety if they are generated mathematically.
- each tile is sized to two focusing elements with hexagonal base diameters.
- each tile is in the shape of a rectangular box that represents two hexagons.
- the collective group of all of the control patterns shown in FIG. 7 completely and evenly covers the tile 24.
- the idea that the control patterns 'completely and evenly' cover the tile, however, is not meant to be limiting.
- the collective group of all of the control patterns may only partially cover the tile, or may cover the tile multiple times ⁇ i.e., several control patterns occupy the same space on the tile).
- FIGS. 8 and 9 the intersection of the grayscale in-plane image 10 with a synthetically magnified image generated by a control pattern of icons is shown.
- the synthetic images are depicted as small rectangles floating above the surface of this exemplary embodiment of the inventive optical security device.
- the surface of the inventive device carries the grayscale in-plane image 10.
- the synthetic images generated by the control patterns of icons can be thought of as being projected onto the surface of the inventive device, they are also shown in these figures as lying on the surface of the device.
- the intersection of the in-plane image 10 and the synthetic image, along with the control pattern distribution, determines what a viewer 26 will actually see.
- the inventive optical security device is tilted towards-away from the viewer, the collective focal points of the focusing elements will effectively shift upward and downward.
- This means that the intersection of a synthetic image with the in-plane image 10 will shift accordingly so that the synthetic image from a new contributing control pattern will highlight the in-plane image.
- the viewer 26 sees the intersection of the synthetic image 28 formed by Control Pattern F with the middle of the in-plane image 10
- the viewer 26 now looking from a different angle, sees the intersection of the synthetic image 30 formed by control pattern D with the middle of the in-plane image 10.
- FIGS. 10 and 11 examples of control pattern distributions, and the resulting images that a viewer would see, are shown.
- the control pattern distribution 32 shown in FIG. 10A is a "hard transition" control pattern distribution, which as alluded to above, results in sharp transitions between the synthetic images generated by the control patterns of icons.
- FIG. 10B the grayscale image 10 is shown for reference purposes along with a collection of views 34 of the intersection between the control patterns' synthetic images and the in-plane image.
- the control pattern distribution 36 shown in FIG. 11A is a "soft transition" control pattern distribution, which as also alluded to above, results in smooth transitions between the synthetic images generated by the control patterns of icons.
- FIG. 11 B the grayscale in-plane image 10 is shown for reference purposes along with a collection of views 38 of the intersection between the control patterns' synthetic images and the in-plane image.
- FIGS. 10B and 11 B Referring to the 'frames' of the animation offered by these exemplary embodiments of the inventive optical security device, which are shown in FIGS. 10B and 11 B, it will be seen that the use of a 'hard transition' control pattern distribution results in a 'hard boundary' between the different control pattern contributions to the in-plane image as a whole, while the use of a 'soft transition' control pattern distribution results in 'soft boundary' contributions to the in-plane image as a whole. In both embodiments, the viewer will see sweeping elevations rolling over a surface shaped like the in-plane image (i.e., a monkey's face).
- the dynamic optical effects demonstrated by the present invention are determined by the relative phasing of the control patterns and by the control pattern distribution, in addition to the nature of the grayscale in-plane image.
- the in-plane image 10 is shown 'filled' with the six (6) control patterns of icons shown in FIG. 6.
- FIG. 13 one of the images (without dynamic optical effects) 40 viewable from a surface of the inventive optical security device employing the 'filled' in-plane image shown in FIG. 12, is illustrated.
- each grayscale image is assigned a column, or "set" of control patterns of icons.
- the method for forming the icon layer in this exemplary embodiment is described above, with the selection of control patterns of icons being carried out for each grayscale image simultaneously, forming an overlay of the results of a plurality of grayscale images.
- a collection of six grayscale images form an animation.
- the control patterns within the same "set” have variation in the vertical direction. That means that, for a given set (or, similarly, for a given grayscale image), tilting in the vertical direction will have the effect of rolling the color through the image in a choreography described by that set's control pattern probability distribution.
- Corresponding control patterns in adjacent sets have variation in the horizontal direction. That means that tilting in the horizontal direction will have the effect of changing the grayscale image and can produce the effect of an animation.
- the sets of control patterns of icons can be coordinated such that there is one effect when the device is tilted towards-away (due to the variation within a set of control patterns of icons) and a different effect when the device is tilted right-left or left-right (due to the variation among the sets of control patterns of icons).
- the icons shown and described herein are rather simple in design, adopting the shape of simple geometric shapes (e.g., circles, dots, squares, rectangles, stripes, bars, etc.) and lines ⁇ e.g., horizontal, vertical, or diagonal lines).
- the icons may adopt any physical form and in one exemplary embodiment are microstructured icons ⁇ i.e., icons having a physical relief).
