Description
Technical field
The utility model belongs to mm-wave imaging technical field, particularly relates to a kind of miniature darkroom for active millimeter wave imaging.
Background technology
Along with people are to the raising of public arena safety problem attention rate, imaging technique for the special occasions such as anti-terrorism, safety check have also been obtained to be applied more and more widely, wherein active millimeter wave imaging technique develops swift and violent in recent years, becomes a large focus of research both at home and abroad.When carrying out active millimeter wave imaging experiment, for preventing the electromagnetic interference of space outerpace, ensureing the accuracy of experimental result, arises at the historic moment in the darkroom of shielding outside electromagnetic interference.Traditional microwave dark room is an a kind of large space six shields be hedged off from the outer world.The structure of microwave dark room is divided into 3 layers from outside to inside, and outermost layer is metal screen layer, plays the electromagnetic effect of insulating space; Middle one deck is ferrite wave-absorbing material, the electromagnetic wave of dominant absorption low-frequency range; Innermost layer is foam of polymers absorbing material, absorbs all frequencies of low frequency tremendously high frequency.Traditional microwave dark room floor space is large, and consumptive material is many, add that absorbing material itself is expensive, therefore construction cost is high, and can not arbitrarily movement after building up.
Utility model content
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of miniature darkroom for active millimeter wave imaging, this miniature darkroom floor space is little; Consumptive material is few, and cost is low; Can carry out in the short period of time dismantling and moving, easy to use.
The technical solution adopted in the utility model is: a kind of miniature darkroom for active millimeter wave imaging, and this miniature darkroom comprises shielding case body and inhales ripple layer, and this suction ripple layer includes certain intervals or without the multiple wave-absorbers be spaced at inside shielding case body; The base that each wave-absorber comprises pyramid and is connected with pyramid, described base is fixed on inside shielding case body.
Preferably, described shielding case body comprises KT plate and is coated on the metal level outside described KT plate.
Preferably, described suction ripple layer is polyurethane foam.
Preferably, described substructure height is the 1/3-1/4 of pyramid 1 height.
Preferably, side, described miniature darkroom offers side door.
Preferably, described miniature darkroom interior corners is spliced to form by adjacent pyramid.
Preferably, described miniature darkroom interior corners is respectively cut half by adjacent pyramid and is spliced to form.
The beneficial effects of the utility model are: miniature darkroom of the present utility model device, and comprise shielding case body and inhale ripple layer, this suction ripple layer comprises the multiple wave-absorbers be arranged in inside shielding case body; The base that each wave-absorber comprises pyramid and is connected with pyramid, described base is fixed on inside shielding case body, the wave-absorber that pyramid and base are formed jointly, and be combined to form described miniature darkroom with shielding case body, floor space is little; Shielding case body is made up of KT sheet material, and consumptive material is few, also removable, easy to use the while that cost being low.
Accompanying drawing explanation
Figure 1A is the structural representation of a kind of embodiment of the utility model;
Figure 1B is wave-absorber schematic diagram;
Fig. 2 is the axonometric drawing of Fig. 1.
Embodiment
Be further described embodiment of the present utility model below in conjunction with drawings and Examples, following examples only for clearly the technical solution of the utility model being described, and can not limit protection range of the present utility model with this.
The utility model provides a kind of miniature darkroom, and be intended to make floor space little, consumptive material is few, and cost is low, and is convenient to dismounting and moves.
As Figure 1A, Figure 1B and the miniature darkroom for active millimeter wave imaging that Figure 2 shows that a kind of embodiment of the utility model, darkroom in present embodiment can be roughly divided into two-layer: shielding case body 3 and suction ripple layer, that is this miniature darkroom comprises shielding case body 3 and inhales ripple layer, inhale ripple layer comprise at regular intervals or be arranged in the multiple wave-absorbers inside shielding case body 3 without compartment of terrain, the base 2 that each wave-absorber comprises pyramid 1 and is connected with pyramid 1, in the inner side of shielding case body 3, shielding case body 3 forms miniature darkroom 4 with suction ripple layer to base 2 fixing (as adhered to).
In this utility model, form the wave-absorber inhaling ripple layer jointly to be formed by pyramid 1 and base 2, pyramid and base are made up of absorbing material, this absorbing material can be such as polyurethane foamed material (as polyurethane foam pyramid absorber), but the utility model is not limited to this, absorbing material can also be other foam of polymers absorbing materials.In addition, the shape of pyramid 1 can similar triangular pyramids or triangle block, and base 2 is fixed on inside shielding case body 3.The miniature darkroom 4 formed by suction ripple layer and shielding case body 3, floor space is little, and consumptive material reduces, and cost is low, and can carry out within a short period of time dismantling and moving, therefore easy to use.
In the present embodiment, shielding case body 3 can be KT plate, and the outside of this KT plate is coated with layer of metal thin layer (can be such as the materials such as copper, aluminium, steel or ferrite), with insulating space electromagnetic wave.Certainly, the shielding case body 3 in the utility model can also be made up of other materials.
KT plate be a kind of by PS particle through foaming generation board core, then through a kind of new material of surface coating pressing, plate body is well-pressed, merrily and lightheartedly, not perishable, be easy to processing.Utilize the feature that KT plate plate body is well-pressed, slim and graceful, this miniature darkroom device can be made to be convenient to mobile.
In the present embodiment, base 2 is highly preferably 1/4 of pyramid 1 height, during to guarantee absorbing material traverse, center of gravity is also in base portion, certain base 2 highly also can be chosen as 1/3 of pyramid height, and when can guarantee absorbing material traverse equally, center of gravity is also in base portion.
In addition, base 2 is highly 1/4 to 1/3 of pyramid height, under can making electromagnetic wave vertical incidence and oblique incidence condition, has fabulous broadband performance, also has good scattering and isolation fade performance simultaneously, is suitable for each position in darkroom.
In the present embodiment, the side in miniature darkroom 4 offers side door 5.
Side door 5 area can be such as 50cm × 50cm, before carrying out mm-wave imaging experiment, regulates the position of wave source and measured object by this.At this, the area value of side door 5 is only example, reasonably can arrange according to practical application.
In the present embodiment, miniature darkroom 4 interior corners can be spliced to form by adjacent pyramid 1.Such as, miniature darkroom 4 interior corners can respectively be cut half by adjacent pyramid 1 and is spliced to form.
The miniature darkroom with as above structure of the present utility model, not only floor space is little, and consumptive material is few, and cost is low, and is convenient to dismounting and moves.
The above is only preferred embodiments of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
