Abstract
The present invention discloses a kind of femtosecond laser generation color image method comprising following steps;1) substrate for being coated with the scumbling bed of material coat red, three color of green and blue the scumbling bed of material respectively on substrate, 2) is divided into several identical color elements；3) it requires to decompose color element according to color image, the different duty for removing the scumbling bed of material of three colors respectively using femtosecond laser forms color image.The present invention does not need the coating for smearing various colors as needed, it is only necessary to which three kinds of coatings can express color requirements, convenient and efficient at low cost.The present invention simultaneously proposes to etch coating using femtosecond laser, quickly, it is fine, accurately remove removing coating.Femtosecond laser fuel factor is small can be reduced etching to greatest extent with damage caused by exterior domain, so that etch areas clean cut.
Description
Technical field
The present invention relates to laser technology fields more particularly to a kind of femtosecond laser to generate color image method.
Background technique
Early in twenty years ago, people, which just contemplate, adjusts the passive micro-slice laser of Q dust-proof in ancient painting dust removal or sculpture, but
Due to the light that passive Q-adjusted microplate is ns, they can still generate heat, perhaps be damaged to picture.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of femtosecond lasers to generate color image method.
The technical solution adopted by the present invention is that:
A kind of femtosecond laser generation color image method comprising following steps;
1) red, three color of green and blue the scumbling bed of material respectively is coated on substrate,
2) substrate for being coated with the scumbling bed of material is divided into several identical color elements；
3) it requires to decompose color element according to color image, removes the different duties of the scumbling bed of material of three colors respectively using femtosecond laser
Than forming color image.
The scumbling bed of material with a thickness of 10 μm -20 μm.
It is one layer or more per the scumbling bed of material of the same colour.
The substrate that the scumbling bed of material is coated in step 2 is divided into several identical color lists according to CCD camera minimum resolution
Member.
The invention adopts the above technical scheme, several layers of three color different colours coating thin layer is coated on substrate, using femtosecond
Clock laser imitates three color image-forming principle of television set and removes one layer of two layers of different duty, one picture of formation at colored principle by three colors
Element is to form colour.Modern color printer is always glossy shinny, can not there is ancient figure effect very well.With computer coloured picture phase
Respective production cromogram is low.The image that the present invention is formed has dimpling recessed compared to the image of existing printing technique, visual effect
It is different.The present invention can be used for making color image especially old road and copy, such as imitative Dunhuang frescoes, excellent.
The present invention does not need the coating for smearing various colors as needed, it is only necessary to which three kinds of coatings can express colour and want
It asks, it is convenient and efficient at low cost.The present invention proposes that, using femtosecond laser etching coating, femtosecond laser has instantaneous power high, focuses
The advantages that hot spot is small, and machining accuracy is high, can quickly, it is fine, accurately remove removing coating, femtosecond laser also has fuel factor small
Advantage can be reduced etching to greatest extent with damage caused by exterior domain, so that etch areas clean cut.
Detailed description of the invention
The present invention is described in further details below in conjunction with the drawings and specific embodiments；
Fig. 1 is step 1 schematic diagram that a kind of femtosecond laser of the present invention generates color image method；
Fig. 2 is step 2 schematic diagram that a kind of femtosecond laser of the present invention generates color image method；
Fig. 3 is step 3 schematic diagram that a kind of femtosecond laser of the present invention generates color image method.
Specific embodiment
As shown in one of Fig. 1-3, wherein label 11 is the red scumbling bed of material, and label 12 is the green scumbling bed of material, label 13
For the blue scumbling bed of material, label 2 is substrate.The invention discloses a kind of femtosecond lasers to generate color image method comprising with
Lower step;
1) red, three color of green and blue the scumbling bed of material respectively is coated on substrate,
2) substrate for being coated with the scumbling bed of material is divided into several identical color elements；
3) it requires to decompose color element according to color image, removes the different duties of the scumbling bed of material of three colors respectively using femtosecond laser
Than forming color image.
The scumbling bed of material with a thickness of 10 μm -20 μm.
It is one layer or more per the scumbling bed of material of the same colour.
The substrate that the scumbling bed of material is coated in step 2 is divided into several identical color lists according to CCD camera minimum resolution
Member.
The invention adopts the above technical scheme, several layers of three color different colours coating thin layer is coated on substrate, using femtosecond
Clock laser imitates three color image-forming principle of television set and removes one layer of two layers of different duty, one picture of formation at colored principle by three colors
Element is to form colour.Modern color printer is always glossy shinny, can not there is ancient figure effect very well.With computer coloured picture phase
Respective production cromogram is low.The image that the present invention is formed has dimpling recessed compared to the image of existing printing technique, visual effect
It is different.The present invention can be used for making color image especially old road and copy, such as imitative Dunhuang frescoes, excellent.
The present invention does not need the coating for smearing various colors as needed, it is only necessary to which three kinds of coatings can express colour and want
It asks, it is convenient and efficient at low cost.The present invention proposes that, using femtosecond laser etching coating, femtosecond laser has instantaneous power high, focuses
The advantages that hot spot is small, and machining accuracy is high, can quickly, it is fine, accurately remove removing coating, femtosecond laser also has fuel factor small
Advantage can be reduced etching to greatest extent with damage caused by exterior domain, so that etch areas clean cut.
