Specific embodiment
Below with reference to specific embodiment, the present invention is described in further detail, it is described be explanation of the invention and
It is not to limit.
The present invention a kind of the digitlization material information acquisition device and method of liquid disperse system, first with combination area source
Emit light, then regulate and control light across sample to be tested, then by the characteristic of corresponding filming apparatus record residual ray, obtains anti-
The digital image information for answering sample to be tested spectral absorption characteristics, as the digitlization material information of sample to be tested.
Wherein, the light-emitting surface for combining area source can be divided into the subelement a more than or equal to n, and n is the integer greater than 1,
The light for wherein having n unit to emit has respectively different characteristics in terms of wavelength composition, intensity and energy；Here
N value selected according to information content and to the practical manifestation ability of the characteristic of sample；For wavelength, area source is combined
Include part or all of Uv and visible light wave band.
The light that combination area source releases, spatially has different characteristic distributions, this is to form the later period, absorbs
The basis of light information complexity afterwards.Can not only value be 10,20,50,100,200；In order to obtain stronger data acquisition energy
The analysis ability of power and later period index of correlation, the numerical value of n can choose bigger, can be in conjunction with suitable light source preparation method
Easily realize several hundred, thousands of or even millions of ranks.
Subelement on light-emitting surface mentioned here, in actual application, it is intended that have between them enough
Otherness.There can be preferable covering to the wavelength and light intensity in the SPECTRAL REGION of research and the combination between them
Degree.Namely respective light characteristic possessed by these subelements, can represent studied spectral regions to the full extent
Domain.This representativeness is largely determined by otherness possessed by the number and each unit of subelement.Under normal circumstances, when
When the number of subelement is less, it is desirable to which the otherness between each subelement is bigger, and when number is larger, difference each other
The opposite sex can be relatively much smaller, and the distribution in space also can be continuously very much.
For combining the device implementation method of area source, mainly realized by two total technology paths, one is building
Then independently luminous small light source splices several such light source two dimensions on the whole to constitute.Another technology realized
Route is the light source generation wavelength composition light abundant for first passing through a totality, then using the method that combination filters come real
It is existing.Optical filtering mentioned here refers to the operation for retaining to certain ingredients in light, and other parts being allowed to pass through.Combination filter
Light just refers to that by different filter effect tissues, on one face, emergent ray actual in this way is exactly to combine area source.This
Kind technology path will can obtain combination area source very rich and controllable by the way that suitable optical device is arranged.
The present invention uses latter technique scheme, and combination area source includes primary light source, for the optics device of light modulation
Part and face combined filters.Optical device said herein for light modulation mainly there is light adjusting to make primary light source
With.It is several below concrete example, a combination thereof form also can be used.One is the light passing sheet materials of surface frosted processing, make light
Become homogeneous soft.One is certain wave bands in the light released to primary light source, have and absorb crown_interception
Optical filter.One is light damping plates, for adjusting and reducing for light intensity.One is filters, such as convex lens, for modulating directional light
Line.
Generally speaking, face combined filters refer to a kind of sheet component, and different suctions are distributed in the different zones on its face
The light absorbing material of light characteristic.The n value being previously mentioned, is exactly realized by the number of different zones on face.Less
In the case where by means of equipment, the method that splicing can be used carrys out the preparation of finished surface combined filters；If it is mass quotient
Industry production, best mode are completed by a series of method of high-precision substance positioning transfers such as a model machine, printer.It is logical
The mode for crossing chemistry printing or printing, prepares on clear sheet.Specific example is referring to subsequent embodiment.
In the present invention, the data of shooting record are obtained by filming apparatus, when carrying out data processing to it, deduct sample blank
Shooting record data, can dramatically increase the variation ratio of light absorption numerical value, improve obtained data and absorption characteristic
Relevance.
The record realized by filming apparatus, acquisition is digitized image information.This digitized image information, can
With there are many avatars and format, most commonly with colour existing for a variety of different picture formats or the image conversion of grey
File can be intuitively presented.It is also possible to record these information using the form of character matrix, although not having intuitive
Presentation property, but for the processing of the data computer in later period, it is same convenient and feasible.
Wherein, the sample to be tested of liquid disperse system is aqueous solution, organic solution or their mixed solution sample.Liquid
The sample to be tested of disperse system is widely present in all trades and professions.It can be the state of acquired original, be also possible to the later period
Pass through the liquid of the approach preparation such as dissolution dispersion.Especially sometimes in order to carry out more extensive chemical analysis, we
Other is often added in some samples facilitates the compound for showing and analyzing, such as various color developing agents, these will
The significant scope of application for increasing sample to be tested.Have especially for urine, saliva, waste water, blood product, beverage etc. and answers extensively
There is more preferable applicability with the sample to be tested of potentiality.
In the present invention to printing or printing ink be not limited, following embodiment only with septichen phenyl ester,
Ortho-nitraniline, 2,4-DihydroxyBenzophenone, 2-hydroxy-4-n-octoxybenzophenone, N- (carboethoxyphenyl)-

The printing template file such as Fig. 6 a- Fig. 6 f is designed first, the signal of six sets of electronics templates is shared, to moulds various in figure
The difference of version, is described as follows.
Printing template is to print specific solution distribution in the plane for controlling printer.We can be under normal circumstances
Using tri- channels CMY come, control printer in approximately the same plane region, be accurately positioned and print several different solution, into
And it can position and to form different assemble.Certainly, for using monochromatic printing the case where, we can thoroughly divide three channels
It is split into as three independent files, each channel in only three channels of printing.But it at this moment needs to each channel
Printing will chromatography, will be accurately positioned.
This group of template of Fig. 6 a has 49 cutting units, and may be configured as 49 n values (and has four repetitions, facilitate error point
Analysis).For being less than 49 situations, can be blocked selectively by some of points with light-proof material.It can get institute in this way
The combined spot species number needed, such as 10,20,30,40 etc..The appearance of template is also possible to square, is also possible to rectangle,
It is even circular.
This group of template of Fig. 6 b, design are one 20 × 20 templates.Referring to the situation in Fig. 6 a, can also can get 50,
