a:Object space basic point is away from image space basic point distance
Note：(geometric sense described above in itself with positive and negative, on index path the geometric sense of all marks it is permanent be on the occasion of)
As shown in figure 4, O1Point and O2Point is respectively the intersection point of the inner and outer wall and the extended line of pipe radius of glass reinforced plastic pipe；H
Put the object focus for glass tube, H ' rear focus for glass tube；lHIt is object space basic point H away from O1The distance of point, if lHIt is worth and is
Canonical H points are in O1The right of point, if lHBe worth is negative then H points in O1The left of point；lH′It is image space basic point H ' away from O2The distance of point, if
lH′Be worth is canonical H ' in O1The right of point, if lH′Be worth for it is negative then H ' in O1The left of point；A values be H points away from the distance of H ',
If required a values is just, in the rights of H points at H '.If required a values are negative, point H ' is in the left of H points.If required a

As shown in figure 4, the plane right-angle coordinate using H points as origin is established, and it is any one to set solid matter in measurement pipe
Point is P, then sets the setting coordinate of P points as (x, y), then the coordinate of P points meets formula (5)：
P(x,y)∈x2+y2≤r1 2 (5)
If the vertical enlargement that gas-particle two-phase flows through glass reinforced plastic pipe after image is β1.According to Newton's formula system, then there is (6) formula：
f:The object space focal length value f ' of lens:The image space focal length value of lens
y:The vertical height y ' of object point:The vertical height of image
x:Distance x ' of the object point away from object focus:Distance of the image planes away from rear focus
Because the refractive index on lens both sides is equal, as shown in (7) formula, then there is (8) formula：
| f |=| f ' | (7)
Formula (8) is brought into (6) and obtains (9) formula：
Then picture point P ' position should be：
Then coordinates of the picture point P ' under plane right-angle coordinate is
Due to installing a flat field apochromatic objective as shown in Fig. 1 and Fig. 5 in P ' left ends.Known flat field apochromatic objective
The vertical enlargement of mirror is β1, conjugate distance L.The picture point P of P ' then through object lens amplification is " in rectangular coordinate systemLocate (wherein, conjugate distance L:Distance of the object plane away from image planes).
Understand that picture point P " is imaged at the front of photographic eyepiece by index path in Fig. 4, it is known that the vertical amplification of photographic eyepiece
Rate is β2, picture point P " is ultimately imaged on photo-sensitive cell through photographic eyepiece and high speed video camera, it can thus be concluded that P " ' away from x-axis
Distance is
Shown in the vertical enlargement such as formula (11) that three-level amplifying device can be obtained through above-mentioned analysis：
β:The overall amplification f ' of three-level amplifying device:For the image space focal length of glass tube
β1:The vertical enlargement f of flat field apochromatic objective:For the object space focal length of glass tube
β2:The vertical enlargement of photographic eyepiece
Image procossing principle：
Image information analysis system as shown in fig. 6, high speed video camera by the image transmitting of the Dual-Phrase Distribution of Gas olid photographed
Into computer, Dual-Phrase Distribution of Gas olid flow condition and concentration, granularity substantially model can be observed by detecting video first
Enclose, to instruct industrial and mineral to produce in real time；The calculation of the image procossings such as row threshold division can be entered by image information analysis system simultaneously
Method analysis provides solid phase particles degree size, estimates out the concentration information of Dual-Phrase Distribution of Gas olid.Its measuring principle is as follows：
The image photographed is handled by image information analysis system can obtain the particle image of solid matter in pipeline,
The processing image-region that a certain size can be chosen on demand is analyzed, because the solid phase particles material photographed is finally in egative film
It is middle to occupy certain pixel cell, the diameter in the pixel cell region occupied by calculating solid phase particles material, in basis
Solid phase particles material grainses degree size in Dual-Phrase Distribution of Gas olid can be finally calculated in the multiple that amplifying device is amplified.It is in addition, logical
Cross granularity pixel the concentration value of shared area than estimating solid matter in the picture；Simultaneously by image information analysis system
System draws the gray-scale map of image, flows experimental result in fact according to the different gray-scale map analyzing and processing values of image and variable grain degree concentration
Comparative analysis, analyzed by statistical data in certain time period, related reflect is established through repeatedly real stream experiment and graphical analysis
Relation is penetrated, provides the concentration of qualitatively Dual-Phrase Distribution of Gas olid, the dense of Dual-Phrase Distribution of Gas olid fluid is provided finally by data anastomosing algorithm
Angle value.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
Enclose and be defined, on the premise of design spirit of the present invention is not departed from, technical side of the those of ordinary skill in the art to the present invention
