Description
Technical field
The utility model relates to human body Examined effect, is specifically related to millimeter wave human body Examined effect.
Background technology
Millimeter wave general reference wavelength is the electromagnetic wave of 1 ~ 10 millimeter, between infrared and microwave, is in the transition period of macroelectronics to microcosmic photonics.Compared with microwave, millimeter wave has higher bandwidth characteristic and resolution characteristic; Compared with light wave, millimeter wave has higher energy conversion efficiency, can through the surperficial imaging of certain material.
Because millimeter wave frequency is very high, so its spatial resolution is also very high; Pulse again due to it is very short so have very high temporal resolution; Meanwhile, because millimeter wave energy is very little, destruction can not be produced to biological tissue, so have the advantage that can not damage human body compared with X ray especially.
Relevant millimeter wave product in the market all requires that checked object has certain residence time before somascope, and whole set equipment volume is comparatively large usually, cannot hide installation, not only reduce circulation place flow of the people, also expose and check place, allow a suspect do some preparations.
Utility model content
The problems such as, inconvenient operation large for the volume existing for existing millimeter wave product, the purpose of this utility model is to provide a kind of small size tunnel formula millimeter wave human body checkout facility, its can be hidden be arranged in corridor, in real time the crowd that corridor back warp is crossed is checked whether keep dangerous material under watching clothing as explosive, pistol etc.
In order to achieve the above object, the utility model adopts following technical scheme:
Small size tunnel formula millimeter wave human body checkout facility, described checkout facility comprises front end data acquisition system, AD converter, high power millimeter wave radiation source and power supply, the output terminal of described front end data acquisition system connects with AD converter data, and described AD converter is connected with power electric; Described high power millimeter wave radiation source is connected with power electric, forms active MMW source.
In above-mentioned checkout facility, described front end data acquisition system comprises teflon electromagnetic wave band lens and focal plane array detector, described teflon electromagnetic wave band lens and focal plane array detector are equipped with, and described focal plane array detector connects with AD converter data.
Further, described teflon electromagnetic wave band lens are specially biotar lens lens arrangement.
Further, described focal plane array detector is the Millimeter wave focal plane array detector of 64 × 64.
Further, each detection infinitesimal on described focal plane array detector processes an antenna structure.
The millimeter wave human body somascope that the utility model provides adopts small-sized focal plane array detector as sensor, coordinate active source, not only can realize the real time imagery effect of video rate, greatly can also reduce volume and reduce weight, passage corner can be arranged on easily as video camera, or other places not easily exposed, have suitable invisible.
Accompanying drawing explanation
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is use principle figure of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1, it is depicted as the structural representation of the small size tunnel formula millimeter wave human body checkout facility that the utility model provides.
As seen from the figure, this human body checkout facility 100 mainly comprises these five parts of teflon electromagnetic wave band lens 101, focal plane array detector 102, high power millimeter wave radiation source 103, AD converter 104, transmit port 105 and electric power system 106.
Wherein, teflon electromagnetic wave band lens 101 are placed in the front end of focal plane array detector 102, and the front end data acquisition system arranging and form whole checkout facility that matches with it, for gathering object by the millimeter-wave signal returned after millimeter radiation source irradiates.
In order to improve the millimeter-wave signal collection effect that front end data acquisition system returns object, teflon electromagnetic wave band lens 101 specifically adopt biotar lens lens arrangement, and focal plane array detector 102 adopts the Millimeter wave focal plane array detector of 64 × 64, and finishing antenna structure on each detection infinitesimal on it.
AD converter 104, it connects with focal plane array detector 102 data, and the signal detected for focal plane detector array 102 carries out digital-to-analog conversion, is convenient to subsequent treatment.
Transmit port 105, as the outbound data transmit port of equipment, connects with AD converter 104, realizes the data after AD converter 104 being changed and externally transmits, carry out subsequent treatment.As connected with the host computer data being mounted with imaging system, sending data in imaging system, carrying out imaging processing.
High power millimeter wave radiation source 103, it is as the radiation source of parts, after being powered up by outside for active radiation monitoring millimeter-wave signal, forms active MMW source.
Electric power system 106 provides stable operating voltage for component working in whole checkout facility, it is electrically connected with AD converter 104 and high power millimeter wave radiation source 103 respectively, for it provides stable operating voltage, AD converter 104 can be stablized and carry out digital-to-analog conversion fast, the reliable and stable active of high power millimeter wave radiation source 103 is to external exposure millimeter-wave signal.
Formed thus small size tunnel formula millimeter wave human body checkout facility, it adopts the Millimeter wave focal plane array detector of 64 × 64 as sensor, target is irradiated with active MMW source, coordinate custom-designed front lens system, expand apparent field angle, realize the regional imaging within the scope of 1m, imaging rate can reach the video rate of 26 frames/s.
According to such scheme formed small size tunnel formula millimeter wave human body checkout facility when specifically using, what whole equipment was hidden is arranged in corridor, and it is connected (as shown in Figure 1) with host computer 200 data being mounted with imaging system by transmit port 105.
After high power millimeter wave radiation source 103 in equipment switches on power, by initiatively to external radiation millimeter-wave signal, when the millimeter-wave signal returned after being irradiated to object by front end teflon electromagnetic wave band lens directional focusing on focal plane array detector 102.
The antenna structure of millimeter-wave signal after focusing on detection infinitesimal is received by focal plane array detector 102, changes subsequently, then by transmit port 105, electric signal is outputted to the enterprising row relax imaging of host computer 200 through AD converter 104.Imaging rate can reach 26 frames/s, and the radiation power of active source is at about 10mw.
As from the foregoing, the small size tunnel formula millimeter wave human body checkout facility that the utility model provides, relative to prior art, will have following features:
A) can to the real time imagery of object, even if the object of movement fast also can carry out perspective imaging preferably;
B) greatly improve target return signal power, enable that detector is easier to carry out concealing article through clothing inspection to passing crowd;
C) substantially reduce volume, that can hide is arranged in corridor, does not arouse attention.
More than show and describe ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
