In the present invention, referring to Chinese patent application CN2016104796476, composite color image can be used to analogy
Method and total light radiant flux control methods and irradiance distribution control methods differentiate material.It is specific as follows：
First, composite color image contrasts
When carrying the imaging detector of imaging optical system using black and white：
1st, spectrum of spectrographic detection characteristic imaging of the material to multispectral light with known substance to multispectral light will be authenticated
Detection feature is imaged side-by-side comparison, intuitively differentiates material for human eye, and this is the contrast for showing common black white image.
2nd, known wavelength visible images are produced with being authenticated matter interaction for multispectral light, addition is corresponding
RGB color intuitively differentiates material to increase the contrast characteristic for being beneficial to human eye figure and differentiating for human eye.
3rd, for multispectral light with being authenticated matter interaction and caused non-visible light (such as ultraviolet light and infrared light)
And image caused by known wavelength, the non-genuine colored contrast characteristic to increase beneficial to the discriminating of human eye figure is added, while again
Using word or the symbol description wavelength as non-visible light.The image software as caused by for ultraviolet light adds gradual change purple with aobvious
Diagram picture, i.e. long wave ultraviolet light image add lavender, short wavelength UV light image to deepen purple；Used for infrared caused image
Software adds gradual change red to add pale red, short-wave infrared light image to deepen red with display image, i.e. LONG WAVE INFRARED light image；It is easy to
Human eye intuitively differentiates material.
4th, for multispectral light and be authenticated matter interaction and caused unknown wavelength caused by image, addition it is non-
True color and the RGB color corresponding with its gray value have the contrast characteristic for being beneficial to human eye figure and differentiating to increase, such as with
Gray scale from weak to strong, its corresponding image can be added from black, purple, red to white color, be easy to human eye intuitively to differentiate
Material.
5th, in the black and white imaging detector with imaging optical system, imaging detector is divided into different small row
Battle array, each small array is made up of some pixels is used as basic probe unit.One is provided with before imaging detector by different optical filterings
The small array of piece composition, the size and pixel of optical filter are same or equivalent, and the optical filter covers the spectrum from ultraviolet to infrared, institute
The light of different wavelength is detected with different pixel cell, for multispectral light and be authenticated matter interaction and it is caused can
See light image (through the light of corresponding visible filter), add its corresponding RGB color to increase and be beneficial to what human eye figure differentiated
Contrast characteristic, intuitively differentiate material for human eye.For multispectral light and be authenticated matter interaction and it is caused it is non-can
See light, such as ultraviolet light and infrared light image (through the light of corresponding non-visible light optical filter), add non-genuine colour to be beneficial to increase

Imaging of the material to multispectral light will be authenticated and be divided into MxN grid of quantity identical, as shown in fig. 7, wherein E '
(m, n, λ) is the irradiation level of (m, n) individual grid in the imaging grid, calculates total light radiation of the imaging grid to multispectral light
Flux is Φ '0(λ) is as follows：
Then defining similarity is：
When similarity R (λ) is 1, it is identical with known substance that expression is authenticated material；Conversely, similarity R (λ) deviates 1 then table
Show that be authenticated material differs with known substance, deviation 1 is more big more differs.LED or laser diode in multispectral light source
(corresponding different wavelength X) can individually or be partly or entirely opened, to obtain different imagings.If for a certain ripple
It is larger that long λ similarity R (λ) value deviates 1, you can it is different from known substance that judgement is authenticated material；Otherwise for all ripples
Long λ similarity R's (λ) is 1 or close to 1, that is, can determine whether to be authenticated material identical with known substance.User's acceptable
The size of similarity is rule of thumb defined by user.
3rd, light irradiance distribution similarity comparison
When carrying out the contrast of irradiance distribution, the irradiance distribution and the irradiation level point of known substance that material will be authenticated
Cloth is contrasted, i.e., known substance is divided into MxN grid to multispectral photoimaging, calculates its grid number with light irradiance E's
S (λ, E) is distributed, such as Fig. 8.Equally, material will be authenticated and MxN grid is divided into multispectral photoimaging, calculate its grid number with
Light irradiance E distribution S'(λ, E), such as Fig. 9.λ is a certain monochromatic wavelength in multispectral light.Defining both similarities is：
Wherein, μ is to consider known substance imaging grid number with irradiation level E distribution S (λ, E) and be authenticated material imaging net
Lattice number with irradiation level E distribution S'(λ, E) contribute similarity weighted and the weighted factor that influences similarity and be multiplied by.Example
Weighted factor, which can such as be defined, is:
When similarity R (λ) is 1, it is identical with known substance that expression is authenticated material；Conversely, similarity R (λ) deviates 1 then table
Show that be authenticated material differs with known substance, deviation 1 is more big more differs.LED or laser diode in multispectral light source
(corresponding different wavelength X) can individually or be partly or entirely opened, to obtain different imagings.If for a certain ripple
It is larger that long λ similarity R (λ) value deviates 1, you can it is different from known substance that judgement is authenticated material；Otherwise for all ripples
Long λ similarity R's (λ) is 1 or close to 1, that is, can determine whether to be authenticated material identical with known substance.User's acceptable
The size of similarity is rule of thumb defined by user.
User can differentiate material with said one or part or all of criterion.If the on the contrary, knot for a certain criterion
Fruit is negative, you can it is different from known substance that judgement is authenticated material.
