Then sample is replaced into neutral filter, measures the output intensity I of sampleS,
NoticeSo
Do not have in the final result of formula (4)(namely) occur, illustrate that the intensity (and its spectrum) of light source is not interfered with
Measurement to sample, as long as all measurements keep lgI all using the calibration of same neutral attenuatorn+AnFor constant constant.
But different occasions are difficult to find duplicate neutral filter, and it is difficult to ensure that the position of sample and neutral filter
Put consistent.For the complexity of complicated solution composition, what simple transmitted spectrum was obtained is the information of whole complicated solution compositions,
Specific aim is poor, and is the measurement accuracy that further raising complicated solution surveys target component, with reference to glimmering with certain scattering
The characteristics of light is with strong points, but influenceed by fluorescence excitation light intensity, optical length and surveyed constituent concentration, cause fluorescence to have sternly
The self-absorption problem of weight, and influenceed by the characteristic of complicated solution strong scattering, cause obtained fluorescence spectrum to have very strong
It is non-linear, therefore the feature of surveyed material can not be reacted well.

To each wavelength of fluorescence spectrum frequency it is consistent with the square wave light frequency that light source is sent, by taking a certain wavelength X of transmitted spectrum as an example,
Fig. 1 is the waveform integrated value schematic diagram corresponding with the spectrum acquisition device time of integration of λ wavelength, and B is ambient noise, and T is spectrum
The time of integration of reception device, and T1=T2=...=Ti=T；T1It is ambient noise that the time of integration is corresponding in interval, this time
The light intensity amplitude that spectrum reception device is received is the integrated value of ambient noise, and numerical value minimum is designated as Imin；TiThe time of integration in interval
Corresponding is the light intensity and ambient noise of λ wavelength, the light intensity amplitude that now spectrum acquisition device is received be λ wavelength light intensity and
The integrated value of ambient noise, numerical value maximum is designated as Imax, T1With TiBetween other times of integration part correspondence ambient noises, separately
The light intensity and ambient noise of part correspondence λ wavelength, therefore resulting integrated value is in (Imin, Imax) interval interior variation.Thus,
In T1~Ti(I is in the interior class value domain that can obtainmin, Imax) integration value sequence, it can be seen that, the integrated value of the wavelength is in (Imin,
Imax) it is interval in change and form cyclical signal, the integrated value of other wavelength is similar, and for strictly with cycle and synchronization
Cyclical signal.Fourier transform is carried out by the time series of the integrated value to each wavelength, with all wavelengths integrated value
Frequency domain fundametal compoment constitute frequency domain in transmitted spectrum, ambient noise can be eliminated, signal to noise ratio is increased substantially.Fluorescence spectrum

Output intensity, b1It is the optical length of the first light path 1, b2It is the optical length of the second light path 2, △ b are the difference of two optical lengths, ∈ extinctions
Coefficient is that c surveys material concentration.
The absorbance of double light path spectroscopic methodologies is still linear with optical path difference it can be seen from formula (7), meet lambert-
Beer law, and with light intensity of incident light IOIt is unrelated.Therefore, double light path methods are not influenceed by light source in theory, are deducted simultaneously
The influence of packaging bag in itself.
The present invention can be produced the characteristic of fluorescence by ultraviolet excitation using particular matter in complicated solution, but in light path side
Different fluorescence intensities are produced with the incident depth difference of ultraviolet light upwards, excite fluorescence to produce the distance of position and receiving position
Difference can cause the self-absorption of fluorescence different, and the material that is stimulated in complicated solution is simultaneously by the shadow of other material concentrations
Ring, when ultraviolet light is by the more of other material absorbings, the ultraviolet light that the material that can be excited is received is fewer, and can be by complexity
The influence of solution scattering, therefore it is very strong non-linear to cause the spectrum obtained to have.And measure and obtain under double light paths at multiposition
Spectrum be the coefficient spectrum of above-mentioned factor, add the information content for the material that is stimulated, greatly inhibit the non-thread of spectrum
Property, and measure with strong points, the influence of transmitted light source change and packaging bag is eliminated, while using constructing transmitted spectrum in frequency domain
The influence of spectral background noise is eliminated with fluorescence spectrum in frequency domain；Greatly improve the essence of complicated solution component content analysis
Degree.The Non-Destructive Testing of packed complicated solution is solved the problems, such as, it is efficient, pollution-free.
