Volatilized into air, simply volatilize number it is distinct, if it is possible to the rapid explosive air volatilization detected in air
Thing, it is possible to track, determine the position of explosive, so as to prevent the generation of blast, therefore, quick, sensitive detection of concealed
Explosive has very important significance.Simultaneously in detection process, without contacting object to be detected, non-contact measurement is realized,
Can be both hidden, it is not crude and rash, the respect to being detected personnel is embodied again, belongs to more civilized detection mode.
Common explosives detection methods, the chemistry of the residual on object to be detected is collected often through the method for contact
Composition, to determine whether to carry or contact explosive, the means, which often compare, to be restricted；Detection process is complicated simultaneously, sensitive
Degree is relatively low, carries inconvenient, can not sometimes provide accurate detection information, and detection time is long etc..
The content of the invention
In order to overcome drawbacks described above, it can contain the invention provides one kind in quick, sensitive non-contact detecting air
Explosive polymer so that follow the trail of detection explosive source nanometer detection device.
The technical scheme that is used to solve its technical problem of the present invention is：A kind of noncontact nanometer explosive detection dress
Put, including light source, nano-sensor, optical filtering, image amplifier, focus lamp, imaging sensor, the image procossing set gradually
Device and display, the nano-sensor are provided with air inlet passage, and scribbling nanometer in the air inlet passage partly leads
Body coating, the light that the light source is sent excites generation fluorescence, the fluorescence of generation by the Nano semiconductor coating of nano-sensor
Optical filtering, image amplifier, focus lamp, imaging sensor are sequentially passed through, last coherent signal enters image processor, the figure
Picture processor is connected with display and light source data, and the light excitation nano coating of light source produces fluorescence, and absorption explosive gas gathers
The nano coating part of compound is quenched, and does not fluoresce.
As a further improvement on the present invention, prism composition, institute are additionally provided between the light source and nano-sensor
State prism to be arranged on nano-sensor, the illumination that light source is sent is incident upon on prism, and passed through prism into nanometer
The Nano semiconductor coating formation fluorescence of sensor.
As a further improvement on the present invention, the air inlet passage side of the nano-sensor is provided with fan, suction
Air.
The beneficial effects of the invention are as follows：The light excitation nano coating of light source produces fluorescence in the present invention, adsorbs explosive gas
The nano coating part of body polymer is quenched, and does not fluoresce, by analyzing this infomation detection explosive, nano level detection side
Formula, therefore high resolution, and accurately judge measured matter；The gaseous volatilization polymer of the detected thing of nano coating absorption, accurately
Degree is high；Optical filtering filters the light of light source, and the light that nano coating is sent can pass through so that signal understands, can handle；Image amplifies
Signal can be amplified and be converted to electric signal by device and focus lamp, further improve resolution ratio, be filled by fan or other blowings
The detected thing gas componant of suction is put, non-contacting purpose is reached.Apparatus of the present invention detection process is simple, sensitivity is high, carries
Convenient, due to taking nano-sensor, accuracy of detection is improved.
