Abstract
The utility model discloses an optical detector of digital watermarks, which comprise a purple light lamp (2) and a power supply switch (3). The utility model is characterized in that the optical detector of digital watermarks also comprise an optical lens (1), wherein a corresponding relationship between the optical lens and a watermark mark printed on each of the objects which need counterfeiting prevention, such as printed matters, tickets, etc. is established. The optical detector of digital watermarks is long; the optical lens (1) is positioned at the front part, the purple light lamp (2) is positioned on the optical lens (1), and the power supply switch (3) is positioned at the front side part. The optical detector of digital watermarks of the utility model only comprises the parts of the purple light lamp, the optical lens, etc.; therefore, the utility model has the advantages of simple structure and compactness; besides, the utility model is a hand-held detection product which is very convenient and practical for people to hold and use.
Description
Technical field
The utility model relates to a kind of watermark detection instrument, specifically, relates to a kind of optical monitoring instrument that is used for watermark detection.
Background technology
Traditional watermark identification is by the reflective mode of fluorescent lamp, and it is false proof that naked eyes carry out the identification mode realization, and watermark recovery is bigger.Along with the development of technology, the popularizing of this technology, this anti-counterfeiting technology can not reach false proof purpose.The product of forging, bill etc. can stamp the anti-counterfeiting watermark recovery the same with actual products too, thereby make this anti-counterfeiting technology lose false proof meaning.This technology mainly exists an anti-counterfei waterprint pattern identification simple, and does not set up the corresponding closed relationship of watermark and checkout equipment, thereby, cause and can not effectively play antifalse effect.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of watermark and checkout equipment corresponding digital watermarking optical detector.
For achieving the above object, the utility model digital watermarking optical detector, comprise ultraviolet light, power switch, it is characterized in that also comprising optical lens, wherein the watermark that is printed in the false proof article of needs such as optical lens and printed matter, bill establishes corresponding relation.
As further improvement, digital watermarking optical detector of the present utility model is a strip, and optical lens is positioned at the front portion, and ultraviolet light is positioned at optical lens, and power switch is positioned at front side portion.
Digital watermarking optical detector of the present utility model is pressed power switch when opening use, ultraviolet light is lighted.The light that ultraviolet light sends, be radiated on the watermark that is printed in the false proof article of needs such as printed matter, bill and produce reflection graphic patterns, this pattern produces the watermark recovery that human eye can be discerned, thereby realizes detecting the purpose of printed matter, papers after selecting, amplify through optical lens.The utility model digital watermarking optical detector only comprises ultraviolet light, several parts of optical lens, and is simple in structure, small and exquisite, for hand-held testing product, carries, uses all extremely convenient and practical.
Description of drawings
A kind of embodiment front view of Fig. 1 the utility model digital watermarking optical detector.
Embodiment
A kind of embodiment front view of Fig. 1 the utility model digital watermarking optical detector.Digital watermarking optical detector in the present embodiment comprises optical lens (1), ultraviolet light (2), power switch (3), and wherein the watermark that is printed in the false proof article of needs such as optical lens and printed matter, bill establishes corresponding relation.This digital watermarking optical detector is a strip, and optical lens (1) is positioned at the front portion, and ultraviolet light (2) is positioned at optical lens (1), and power switch (3) is positioned at front side portion.The bottom of digital watermarking optical detector is a battery cover 4, and the middle part is the battery storing position, and is furnished with the driving circuit of ultraviolet light (2).
As specific product digital watermarking optical detector, long: 82mm, wide: 25mm, height: 12mm.The optical lens that adopts is single convex lens, and the optics chromatogram is qb4, diameter 24mm, focal length 120mm, thickness 3mm.
The digital watermarking optical detector is pressed power switch (3) when opening use, ultraviolet light (2) is lighted.The light that ultraviolet light sends, be radiated on the watermark that is printed in the false proof article of needs such as printed matter, bill and produce reflection graphic patterns, this pattern produces the watermark recovery that human eye can be discerned, thereby realizes detecting the purpose of printed matter, papers after selecting, amplify through optical lens.The utility model digital watermarking optical detector only comprises ultraviolet light, several parts of optical lens, and is simple in structure, small and exquisite, for hand-held testing product, carries, uses all extremely convenient and practical.
The utility model is not limited to the scope of embodiment, and all innovation and creation that utilize the utility model design are all at the row of protection.
Claims (2)
1. a digital watermarking optical detector comprises ultraviolet light (2), power switch (3), it is characterized in that also comprising optical lens (1), and wherein the watermark that is printed in the false proof article of needs such as optical lens and printed matter, bill establishes corresponding relation.
2. digital watermarking optical detector according to claim 1 is characterized in that, described digital watermarking optical detector is a strip, and optical lens is positioned at the front portion, and ultraviolet light (2) is positioned at optical lens (1), and power switch (3) is positioned at front side portion.
