The application requirement in equal fields.
Description of the drawings
Fig. 1 is the longitudinal cross-section layout structure schematic diagram of the present invention.
Fig. 2 is the lateral cross section structural schematic diagram that the present invention is sliced
Specific implementation mode
The specific implementation mode of the present invention is described in detail below in conjunction with the accompanying drawings.
Embodiment：As shown in Fig. 1~Fig. 2, combined type of the present invention slice X-ray regulation and control device by its appearance and size of multi-disc according to
The secondary slice 1 for reducing and being arranged in order forms, and the hole path 11 and arrangement mode one of identical quantity are included in every a piece of slice 1
It causes, it is horizontal to originate the hole path lateral cross section that the hole path section horizontal span on the slice of arrangement is more than on the slice of ending arrangement
To width, X-ray is incident by starting slice hole path arrival end, and being transmitted to ending via multiple total reflection in hole path 11 cuts
The hole path outlet end of piece is emitted.
Further, the section of hole path 11 and the section of the slice 1 are rectangular；Slice 1 longitudinal cross-section in etc.
Waist is trapezoidal.Further, hole path 11 is arranged in order by row from top to bottom.
Further, the hole originated on the slice that the hole path section horizontal span on the slice of arrangement is ending arrangement is logical
Imaging area can be extended to 100 times or more by 10 times or more of road lateral cross section transverse width.While in order to meet x-ray
Total reflection condition, the quantity of rectangular micropore slice also accordingly increases in device, and the shape to ensure adjacent prismatic micropore slice is poor
It is different smaller, it there will be neither the loss in efficiency of transmission in this way, and the amplification of detection area can be obtained.The device has X-ray
Good efficiency of transmission, it is very strong to the judgement of x-ray incoming position, into the amendment of excessively a series of X-ray intensities and distribution,
The radioscopic image detected through X-ray position sensitive detector can be restored well, and can identify that X is penetrated in space well
Line point source obtains spatial position, energy and the strength information of X-ray point source.
Further, combined type slice X-ray regulation and control device further includes position sensitive X-ray detector 2, position sensitive X
The arrangement mode of hole path of the ray detector 2 in the slice hole path outlet end for being positioned over ending arrangement, slice 1 and position
The arrangement mode for setting the detection infinitesimal of sensitive X-ray detector 2 is consistent.Preferably, position sensitive X-ray detector 2 is bonded close
At the slice hole path outlet end 1-2mm of ending arrangement.Position sensitive X-ray detector 2 can directly obtain exit Xray
The position of photon, energy information.Pass through the position correspondence of outlet end micropore and arrival end micropore, it may be determined that incident X is penetrated
The incoming position of linear light.By the amendment of a series of X-ray intensity and distribution, combined formula slice X-ray can be restored
Regulate and control the radioscopic image of device arrival end incidence.
The production method that the present invention is sliced,
Step 1 draws out solid rectangular sub- pipe by wire drawing machine later by square glass pipe addition packing material；
Rectangular sub- pipe is arranged in order by row by mold and is drawn out by wire drawing machine solid compound by step 2 up and down
Rectangular sub- pipe；
Step 3, drawn by mold by compound rectangular sub- pipe by row proper alignment and by wire drawing machine it is secondary compound rectangular
Centrum；
The re-compounded centrum of stretch forming is cut into the rectangular slice that thickness is 3mm by step 4；
The rectangular slice being cut into finally is put into chemical reagent and erodes packing material by step 5, is obtained square hole and is cut
Piece.
Combined type square micropore slice X-ray regulation and control device is a kind of novel multiple capillary X-ray regulation and control device, by multi-disc size
The rectangular micropore slice being sequentially reduced is composed.Include in slice per square piece micropore the micro channel of identical quantity and
Arrangement mode is consistent, and micro channel section and serial section are rectangular.The arrangement mode of micropore in rectangular slice and position
The arrangement mode that sensitive detector detects infinitesimal is consistent, it can be achieved that micropore is corresponding with detection infinitesimal.Between the micropore slice of direction
Position be determined by calculation, phase can only be entered with the X-ray of (i, j) a micropore outgoing in a piece of micropore slice before ensureing
In (i, j) a micropore under neighbour in a piece of micropore slice, without the X-ray for interfering other positions micropore to receive.According to
This combination is arranged in order the rectangular micropore slice of multi-disc and constitutes combined type square micropore slice X-ray regulation and control device, can
Ensure only to be emitted from a micropore in device outlets end (i, j) by the X-ray of a micropore incidence of device arrival end (i, j), it is right
The X-ray between micropore is answered not interfered with each other in transmission process.It is much larger than outlet end size using an arrival end size
Combined type square micropore slice X-ray regulate and control device, the X-ray in wide area can be converged to compared within the scope of small area.
Position sensitive detector is mounted on combined type square micropore slice X-ray regulation and control device outlet end, utilizes position sensitive detector
Position the photon of each micropore outgoing.In being sliced per a piece of micropore in combined type square micropore slice X-ray regulation and control device
The information of micropore is transmitted by the micropore of corresponding position, and the X-ray information between micropore is simultaneously noiseless, therefore outlet end
X-ray information have no change relative to arrival end, only the x-ray imaging of outlet end becomes the S of arrival endout/SinTimes
(SoutAnd SinThe respectively area at device outlets end and arrival end).Combined type square micropore, which is restored, by mathematical computations is sliced X-ray
The X-ray information for regulating and controlling device arrival end can realize that large area x-ray is imaged.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
