Capillary glass tube X-ray optic based on total reflection principle can be realized to high-power broadband X-ray
Regulation, makes X-ray be converged to diameter up to tens microns of X-ray microbeam, improves the utilization rate of X-ray.
Single capillary includes Taper Pipe, ellipsoid pipe, parabolic spool etc., is mainly used for the micro- of synchrotron radiation and Routine Test Lab
Beam X-ray fluorescence analysis and the research of micro-beam X-ray diffraction analysis.
For the length of glass single capillary usually within 10cm, internal diameter is generally 100~500 μm.
Internal diameter is a very important parameter for capillary assessment, it has decision to efficiency of transmission, focal spot size etc.
Property influence.
But the influence of the refraction due to light is unable to measure the internal diameter of capillary glass tube with general physical method.
Utility model content
In view of the above-mentioned problems, the utility model provide it is a kind of using X-ray measurement capillary glass tube internal diameter and the dress of profile
It sets.

Utilize X-ray measurement capillary glass tube internal diameter and the device of profile, including x-ray source, high-resolution X-ray CCD
Camera, the high-resolution X-ray CCD camera are located in the optical path of x-ray source, and glass single capillary to be measured is located at X
In optical path between radiographic source, high-resolution X-ray CCD camera, filled with stream inside the glass single capillary to be measured
Body medium.
Wherein, the x-ray source is micro- focal spot cone-beam X-ray source.
The capillary glass tube after being filled with fluid media (medium) is carried out using laboratory micro- focal spot cone-beam X-ray source and detector
CT imaging can measure the internal diameter and profile of capillary glass tube after the calculating amendment to picture.Detector is high-resolution X
Ray CCD camera.
It is provided by the utility model using X-ray measurement capillary glass tube internal diameter and the device of profile, the fluid of filling is situated between
Matter and the assimilation effect that glass phase compares X-ray are stronger, enhance the edge contrast of imaging, micro- focal spot cone-beam X-ray is to glass
There is amplification when capillary imaging, substantially reduce the error of capillary inner diameter measurement.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
It is described in conjunction with specific technical solution of the attached drawing to the utility model.
As shown in Figure 1, using X-ray measurement capillary glass tube internal diameter and the device of profile, including x-ray source 1, high-resolution
Rate X-ray CCD camera 4, the high-resolution X-ray CCD camera 4 are located in the optical path of x-ray source 1, glass to be measured
Single capillary 2 is in the optical path between x-ray source 1, high-resolution X-ray CCD camera 4, single mao of the glass to be measured
Fluid media (medium) 3 is filled with inside tubule 2.The x-ray source 1 is micro- focal spot cone-beam X-ray source.
Using x-ray source 1 and high-resolution X-ray CCD camera 4 to single mao of glass to be measured after being filled with fluid media (medium)
Tubule 2 carries out CT imaging, after the calculating amendment to picture, can measure the internal diameter and profile of glass single capillary 2 to be measured.
There is amplification when micro- focal spot cone-beam X-ray is to image objects, effectively reduce the measurement error to imaging.
Detector in the present embodiment equipment therefor uses high-resolution X-ray CCD camera, but alternatively, can also
Think the high-resolution detector of other energy real time imageries.
Glass single capillary 2 to be measured is packed into fluid media (medium) BaSO through capillary action in advance4Solution increases imaging
Edge contrast, but alternatively, can also not will cause corrosion using other pairs of glass and the small absorption coefficient of adsorptivity is greater than glass
The fluid media (medium) of glass is filled.
Glass single capillary 2 to be measured is fixed on to the center of turntable vertically, opens light source irradiation, acquisition several groups are different
Projecting gray scale images under angle will be rebuild after these image procossings by algorithm, and the difference of available capillary glass tube is disconnected
The image of layer.
Any faultage image is taken, pixel number shared by internal diameter can be read, the pixel number with whole image side length
The ratio between be equal to internal diameter projected length and projection window practical side length ratio.
The projected length of internal diameter and the ratio of its physical length are equal to projective amplification ratio, and (light source spot size to CCD projects window
Distance and light source spot size to turntable center ratio of distances constant), projective amplification ratio can be calculated by actual measurement, learn throwing
The projected length of shadow amplification ratio and internal diameter can calculate the length of internal diameter at this tomography.
In conjunction with the explanation and practice of the utility model disclosed here, the other embodiments of the utility model are for this field
Technical staff will be readily apparent and understand.Illustrate and embodiment be regarded only as being exemplary, the utility model it is real
Scope and spirit are defined in the claims.
