Description

A kind of new X-ray energy expansion device device

Technical field

A kind of X-ray detection technology is the utility model is related to, specially a kind of new X-ray energy expansion device device.

Background technology

Current nondestructiving inspecting equipment, because X-ray tube emergent light is cone-beam transmitting, works as light-emitting window in imaging process is detected When having certain distance with testee, light intensity that testee edge illumination arrives is naturally weaker than the light intensity of centring point (can be with Isoceles triangle form is interpreted as, vertical line is shorter than stringcourse), it is poor in the presence of power due to being punched in penetrating capacity on testee, so as to It is too high and penetrate to cause on image to exist distortion, stretching and local energy, can typically go to correct by software, but due to soft Part is corrected to go definite value to correct according to article size thickness, so real-time is poor.

So device can realize that X ray is gone out into light energy is beforehand with smooth optical filtering processing, so that energy acceptance is relative Uniformly, image imaging nature is just uniformly true.

Utility model content

The purpose of this utility model is, there is provided one kind tool realizes that X ray is gone out into light energy is beforehand with smooth optical filtering processing, So that energy acceptance is relatively uniform, the uniform real new X-ray energy expansion device device of image imaging nature.

Technical scheme is used by solving its technical problem：A kind of new X-ray energy expansion device device, including X are penetrated Spool, parabola optical filter, optical filter retainer, object to be detected and detector, the X-ray tube send X-ray beam simultaneously Beaten through object to be detected on detector, the parabola optical filter is located on optical filter retainer, and the parabola filters Piece is by X-ray beam and between X-ray tube and object to be detected.

Preferably, the parabola optical filter is raised type parabola optical filter.

Preferably, the parabola optical filter is concave parabola optical filter.

It is of the present utility model to be applied to that there is advantages below：New X-ray energy expansion device device of the present utility model leads to Cross and install parabola optical filter additional to x-ray source light-emitting window to spectral energy curve smoothing optical filtering processing, make reduction image due to energy Amount is uneven, and to produce distortion, stretching and local energy too high and penetrate, so that image more smoothly clearly tends to be true.

Brief description of the drawings：1st, X-ray tube, 2, parabola optical filter, 3, optical filter retainer, 4, X-ray beam, 5, be detected Object, 6, detector.

Embodiment

A kind of as illustrated, new X-ray energy expansion device device, it is characterised in that：Including X-ray tube (1), parabola Optical filter (2), optical filter retainer (3), object to be detected (5) and detector (6), the X-ray tube (1) send X ray light Beam (4) is simultaneously beaten on detector (6) through object to be detected (5), and the parabola optical filter (2) is located at optical filter retainer (3) on, the parabola optical filter (2) is by X-ray beam (4) and between X-ray tube (1) and object to be detected (5).

In the specific implementation, can with shown in Fig. 2, when run into detection object for the thick determinand in intermediate thin both sides when, it is described Parabola optical filter (2) uses raised type parabola optical filter, and now X-ray beam is at the center of raised type parabola optical filter The path of position is longer, and decay is more, so that the energy at the edge of determinand and centre position is more uniform.

Can with shown in Fig. 3, when run into detection object for the thin determinand in thick middle both sides when, the parabola optical filter 2 For concave parabola optical filter, now X-ray beam is shorter in the path of the center of concave parabola optical filter, declines Subtract less, so that the energy at the edge of determinand and centre position is more uniform.

Using the above-mentioned desirable embodiment according to utility model as enlightenment, pass through above-mentioned description, relevant staff Various changes and amendments can be carried out in the range of without departing from this item utility model technological thought completely, this item is practical New technical scope is not limited to the content on specification, it is necessary to determines that its is technical according to right Scope.
