Description
Technical field
The present invention relates to a kind of pick-up unit, particularly a kind of noncontact nanometer exploder detecting device.
Background technology
Peace and development has become the theme of the world today, but attack of terrorism activity happens occasionally, cause casualties and the panic main the type of raid that remains terrorist's employing on a large scale by blast, due to RDX, PETN, the nitro compound such as TNG and TNT is because its blast particulate is large and low price is often used by terrorist, any explosive all can volatilize in air, just volatilization number distinct, if can detect rapidly airborne explosive air volatile matter, just can follow the tracks of, determine the position of explosive, thereby the generation of prevent exploding, therefore, fast, the explosive of sensitive detection of concealed has very important significance.In testing process, without contact object to be detected, realize non-contact measurement simultaneously, can be both hidden, not crude and rash, embody again the respect to detected personnel, belong to more civilized detection mode.
Common explosive detection method, often the method by contact is collected the residual chemical composition on object to be detected, carries or contacted explosive determining whether, and these means are often more restricted; Testing process complexity simultaneously, sensitivity is lower, carries inconvenience, and accurate detection information sometimes can not be provided, and detection time is long etc.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides the explosive polymkeric substance containing in a kind of non-contact detecting air that can be quick, sensitive, thereby follow the trail of the nanometer detection device of surveying explosive source.
The present invention for the technical scheme that solves its technical matters and adopt is: a kind of noncontact nanometer exploder detecting device, comprise the light source setting gradually, nano-sensor, optical filtering, image amplifier, focus lamp, imageing sensor, image processor and display, described nano-sensor is provided with air admission passage, in described air admission passage, scribble Nano semiconductor coating, the light that described light source sends excites generation fluorescence by the Nano semiconductor coating of nano-sensor, the fluorescence producing light microscopic after filtration successively, image amplifier, focus lamp, imageing sensor, last coherent signal enters image processor, described image processor is connected with display and light source data, the optical excitation nano coating of light source produces fluorescence, the nano coating part cancellation of absorption explosive gas polymkeric substance, do not fluoresce.
As a further improvement on the present invention, between described light source and nano-sensor, be also provided with a prism composition, described prism is arranged on nano-sensor, and the irradiation that light source sends, to prism, and enters the Nano semiconductor coating formation fluorescence of nano-sensor through prism.
As a further improvement on the present invention, air admission passage one side of described nano-sensor is provided with fan, air amount.
the invention has the beneficial effects as follows: in the present inventionthe optical excitation nano coating of light source produces fluorescence, and the nano coating part cancellation of absorption explosive gas polymkeric substance, does not fluoresce, by analyzing this information explosive detection, and nano level detection mode, therefore resolution is high, and accurately judges measured matter; Nano coating absorption is detected the gaseous volatilization polymkeric substance of thing, and degree of accuracy is high
;optical filtering filters the light of light source, and the light that nano coating sends can pass through, and makes signal clear, can process; Image amplifier and focus lamp can amplify signal and be converted to electric signal, further improve resolution, are detected thing gas componant by fan or the suction of other blowing devices, reach non-contacting object.Apparatus of the present invention testing process is simple, highly sensitive, easy to carry, and owing to having taked nano-sensor, accuracy of detection improves.
