Embodiment
The ultimate principle of the utility model foundation is interference of light.When light through a multi-layer optical film was, because the interior change of refractive of assembly of thin films, light can produce the phenomenon of interference, and promptly the light in part zone can strengthen because be concerned with, and the light in another part zone can weaken because cancel out each other.No matter be that light all will be followed Bragg's law from the multilayer film reflection or through multilayer film, for simplicity, do explanation with monofilm, that is: here
Here, λ is an optical wavelength, and θ is the angle of light degree.D is a film thickness, and n is the refractive index of membraneous material.The relevant enhancing of light occurs in δ=2 π, 4 π ..., 2m π, wherein m is a natural number, that is to say:
mλ＝2dcosθ. (2)
In the scope of visible light, just in 375nm～800nm scope, light can produce an interference spectrum because of coherent phenomena, as shown in Figure 1.This interference spectrum shows as specific color under people's naked-eye observation.
When changing multi-layer film structure, that is to say the rete order that changes assembly of thin films, the refractive index of thicknesses of layers or film material all will change the interference spectrum of light transmission or reflection.Like this, transmission or catoptrical interference spectum will have the uniqueness that oneself can not obscure as fingerprint.Because these spectrum all are shown as fixing color under people's naked eyes, can be perceived by people, so interfere formed spectrum can be used as password by these multi-layer optical films.The design of multilayer film itself also just can be regarded as password is being set.
Optical filter through the design of special film system can be a bandpass filter.This special film system is characterised in that a certain layer thickness in the film system that to make a thickness be visible wavelength 1/4 doubles, and when becoming visible wavelength 1/2 λ, can realize the function of bandpass filtering like this.It can make the light of some wave band pass through selectively, and allows the light of other wave band disappear because of interfering, as shown in Figure 2.This function can be called as decoding, and this function can be utilized to carry out the false proof pseudo-work of debating.
Double insurance described in the utility model is false proof debates pseudo-spectrum and establishes yard decoding device and make according to an above-mentioned principle.It is formed by establishing chip reconciliation chip.As shown in Figure 3, the core of establishing chip reconciliation chip is multi-coated interference film 2, and multi-coated interference film 2 combines with substrate 3 surfaces by the mode of plated film or printing, and light 1 is radiated on the multi-coated interference film 2.The assembly of thin films of multi-coated interference film for being formed by stacking by the two-layer or two-layer above dielectric material with different refractivity, its composition can adopt such as Ti

2/ MT/SiO
2)
MHere MT can be transition metal Al, Cr, and Ag, any one of Cu etc., its rete is several different according to false proof needed spectrum complexity, does not wait can be from 2 layers to 300 layers.This multi-coated interference film can be made by the accurate controlled vacuum coating technology of various thicknesses of layers, such as sputter, and electron gun evaporation, the indirect sputter of ion gun, chemical reaction plated film, electroless-plating or the like.
If it is plates that chip is conciliate the substrate of chip, its material can be multiple for glass, crystal, plastics, metal, pottery, man-made fiber, synthetic material etc.
If the lip-deep multi-coated interference film of chip is divided into two parts, is called and establishes yard plated film and background plated film.If the sign indicating number plated film is made into specific literal or pattern according to actual needs, be coated on the surface of blank substrate.In all the other positions of substrate surface is the background plated film.This can realize by covering cover substep plated film or printing technology.The color of background plated film is identical with the color of establishing yard plated film, has peak value separated from one another but difference is the interference spectrum transmissivity distribution of establishing yard plated film, just as shown in Figure 4.Therefore, when changing observation angle, significant change can take place in the interference spectrum color with this specific character.And if background adopts the print force formula to make, self there is not assembly of thin films in it; If the background plated film adopts the method directly be coated with to make, also have on it and establish yard identical assembly of thin films of plated film color, but the peak Distribution of this background plated film interference spectrum is different with the peak Distribution of establishing yard plated film.Like this, as shown in Figure 5, when the people is in zero degree (being the normal direction of membrane plane) observation, establishes the pattern of establishing yard plated film in the chip and be submerged in the background plated film, be difficult to identified; And when people change viewing angle, because the wavelength of light that interferes changes to some extent, significant change also takes place in corresponding spectral color, identical with it change color then can not take place in the background plated film, this yard plated film obvious color of establishing changes the different change color of the background plated film different with peak Distribution or does not change and forms a sharp contrast, thereby the pattern of establishing yard plated film is separated out from the background plated film, as shown in Figure 6, can know identification for people.
Separating chip is to utilize the interference of light to compose and filter to lead to a bandpass filter of light.Decoding film system is coated on the transparent substrate, on the substrate of making as glass, crystal or transparent plastic sheet, designs this band of separating on the chip and leads to the position according to establishing the diverse location of establishing yard plated film and two kinds of different films crests that system occurs of background plated film on the chip.As shown in Figure 7, cover on when establishing on the chip when separating chip, a peak value on a peak value being arranged and separate chip on having only in the spectrum of establishing on the chip of establishing yard plated film overlaps, and a peak value on not having any peak value and separate chip in the background plated film overlaps.Therefore, separate chip and resemble and to establish yard plated film the bandpass filter and display, simultaneously background is filtered out fully with a kind of color.This process is exactly the decode procedure of this patent.We call the decoding film to this multi-coated interference film, and corresponding chip is separates chip.
The utility model is established yard plated film and is made into specific trade mark or literal pattern and background plated film and is coated on the substrate step by step in use, and substrate itself can be attached to by the mode that hot pressing is transmitted on the false proof commodity or file wanted.Owing to establish the spectral characteristic of yard plated film, when the people when zero angle is observed, it is extremely difficult or can not be identified to establish yard plated film pattern.At this moment, there are two kinds of force methods to identify with establishing a yard plated film pattern.The one, any axis rotates in yard face along establishing with establishing chip, that is to say the angle that changes observation.When observation angle changed, the effective film thickness of establishing yard plated film of multilayer changed, and at this moment established chip interference spectum integral body and moved to the shortwave direction, also can change so establish the color of yard plated film, and this variation was different from background plated film change in color.This phenomenon can be used as our the false proof first step of debating puppet, and we are referred to as self check.In addition, the chip of separating that will have above-mentioned film layer structure is placed on and establishes on the chip, according to the interference of light and the principle stated above, even under the observation of zero degree, the pattern of establishing yard plated film can be separated identifying equally from the background plated film, thereby make the pattern of establishing yard plated film can be identified.Here it is false proof second step of debating puppet of this device, and we are referred to as auxilliary inspection.By these two steps, this false proof device can have good anti-counterfeiting performance, this just the utility model be called as that double insurance is false proof debates the reason that pseudo-spectrum is established yard decoding device.
According to the concrete needs of commodity counterfeit prevention, this double insurance is false proof, and to debate the chip of establishing that pseudo-spectrum establishes in yard decoding device can be that transmission-type can be a reflection-type also, must be transmission-type but separate chip.
Because the structure of multi-coated interference film is slightly different, its corresponding spectrum just has tangible difference, and separate in the chip interference spectum peak value and establish in the chip peak value on the icon spectrum fully correspondence just can reach the decoding purpose, so originally establish the characteristics that chip reconciliation chip has uniqueness.In addition, the structure of multi-coated interference film hardly may be by research interference spectum and reverse resolution comes out, and therefore, this false proof device has fabulous anti-counterfeiting performance.If this false proof device carries out large-scale production, cost can fall very lowly, is fit to large-scale promotion and uses.
What need statement is that specific embodiment of the present utility model has been done detailed explanation to summary of the invention of the present utility model.For one of ordinary skill in the art, the any conspicuous change of under the prerequisite that does not deviate from the utility model spirit, it being done, particularly, all constitute to the utility model infringement of patent right, with corresponding legal responsibilities to the replacement that is equal to of some parts.
