Background technology
In existing product, a part is that to take the strict radioactivity two class CO.60 that control of country be radioactive source, and it is radioactive source that another part be take macro-energy X ray accelerator, is characterized in irradiating tested object with its tool macro-energy, with the large penetration power of tool, is checked.As existing, with X-ray examination equipment least energy, be high pressure 600KV electric current 20MA, it is not only auxiliary that to penetrate energy large, and it is also many to consume the energy, as even more serious as the radioactive source environmental pollution as CO.60, and the nuke rubbish produced only has the just recyclable processing of national specialized department, as used institute's a large amount of nuke rubbish that produced on a large scale, can cause the pressure recovery that tool is large to national specialized department.Now the detector of the detection system of operation is many reaches 700 multichannels, more than minimum Ye get tetra-tunnels, and complex process, the simplest operation procedure of existing equipment be after data that the signal surveyed with detector is stored through storer are contrasted again treated device carry out analyzing and processing, judge contained article in car according to curvilinear motion, can not be by the direct real time imagery of contained article in car.
Summary of the invention
In order to solve, the energy resource consumption of existing counter vehicle detecting system is large, environmental pollution is serious, can not be by the defect of the direct real time imagery of contained article in car, the invention provides the real-time perspective imaging system of a kind of X ray container car, this device is not only simple in structure, and imaging effect is good.
The present invention solves the technical scheme that its technical matters takes: this invention is to consist of X-ray emitter, high resolution optical imaging device, high sensitivity image display.
The X-ray emitter, by the high-frequency and high-voltage module, the high-frequency and high-voltage bag, times die block, the X-ray power valve, refraction forms the tooth condenser lens.
The high resolution optical imaging device adopts the principle of low light level imaging to be designed, establish many in optical image former, many group optical transition lens and one or more groups back-illuminated type electron multiplication camera form, and realize omnidirectional detection, and optical image former adopts low energy high definition resolution imaging technology.
After optical image former carries out imaging processing to photon, be transformed into electronic signal and pass to image pick-up card after computer numeral is processed, be imaged on the high sensitivity image display and can show in real time contained images of items in car,, reach low-yield emission X-ray high resolution imaging effect.
The real-time container car perspective imaging of this X ray system is an intelligent automatic checkout system, after vehicle cab crosses, the X-ray emitter sends X-ray automatically, automatically avoiding pilothouse is only detected compartment emission X-ray, optical image former is synchronizeed with the X-ray emitter and is carried out photon switching and process, after vehicle crosses, system is closed automatically, and price is the sixth of like product.
The invention has the beneficial effects as follows: this device is a kind of energy-saving and environmental protection, safe, real-time, economical and practical X-ray low light level perspective imaging system.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of the real-time perspective imaging system of X ray container car.

Embodiment
Be the structural representation of the real-time perspective imaging system of X ray container car as shown in Figure 1, this device comprises: X-ray emitter (1), high resolution optical imaging device (2), high sensitivity image display (3).
X-ray emitter (1), by the high-frequency and high-voltage module, the high-frequency and high-voltage bag, times die block, the X-ray power valve, refraction forms the tooth condenser lens.
Its principle of work is to be transformed into the high-frequency direct-current high-voltage power supply after high-pressure frequency-conversion is module integrated by DC low voltage power supply, input high-frequency and high-voltage bag, the high-frequency and high-voltage bag enters high pressure times die block after the high-frequency direct-current high-tension current is integrated, again carrying out the high-frequency direct-current high-tension current is integrated, after again integrating, input starts the X-ray power valve, the X-ray power valve is activated by refraction the tooth focus lamp, launch low-yield focusing bar wire X ray device, its output power: high pressure 140KV electric current 0.6MA power 110W.Described environmental protection the present invention adopts ultra-low calorie emission bar present situation focused beam, and X-ray scattering index and leakage index adopt omnidirectional detection within all being controlled at the national regulation index.
High resolution optical imaging device (2) adopts the principle of low energy imaging to be designed, establish the optical transition of group more than many lens in optical image former and form and realize omnidirectional detection with one or more groups back-illuminated type electron multiplication camera, optical image former adopts low energy high definition resolution imaging technology.
Principle of work is: more than first group grouping optical transition lens display light source by line and convert to and tell the row integrated light source in person, realize the whole translation function of line source and area source, can allow photoreceptor fully effectively capture light source.
Second group of lens convert the large tracts of land light source to small size integrated optical source after receiving the light source that first group of lens transfer.Enter photon enhancing system and carry out photon amplification integration filtration, refrigeration noise reduction process.
The 3rd group of lens are again integrated conversion process after receiving second group of light source transferred, and photon signal is passed to back-illuminated type electron multiplication camera, and through semiconductor refrigerating, denoising reaches the enhancing overall picture quality, completes the program by the photon converted image.
After optical image former carries out imaging processing to photon, be transformed into electronic signal and pass to image pick-up card after computer numeral is processed, be imaged on display and can show in real time contained images of items in car, high sensitivity image display (3), reach low-yield emission X-ray high resolution imaging effect.Described low light level imaging technique is that low-yield present situation X ray presented to picture rich in detail after multiple lens and many group high-resolution optical camera processing.
