Abstract
The invention discloses an infrared stealth light trapping structure of a moving target. A light trapping microstructure layer is arranged on the surface of the moving target, the cross section of the light trapping microstructure layer is formed by a plurality of isosceles triangles, and the length of the bottom edge of each isosceles triangle and the height of each isosceles triangle are in micron dimensions. According to the infrared stealth light trapping structure of the moving target, a microstructure of which the cross section is formed by the plurality of isosceles triangles is manufactured on the surface of an elastic body by utilizing the electromagnetic coupling characteristic of light and the microstructure, so that infrared trapped light is realized, and the reflectivity and emissivity of the moving target are reduced, thereby reducing the detected possibility of the moving target.
Description
Technical field
The present invention relates to infrared stealth technology field, and in particular to the stealthy light trapping structure of a kind of mobile Infrared Targets and red
Outer invisible method.
Background technology
Ballistic missile is the important composition strength for safeguarding China's national defense safety, but with the development of technology, it is especially various
The development of Detection Techniques, brings huge challenge to the prominent anti-of guided missile, wherein especially most typical with the missile defense program in the U.S.
Property, its Infrared Detectors accounting 30% or so, and in the precision guided weapon that various countries use, 60% is infrared guidance according to statistics.
The report of current projectile flight section infrared stealth is rare.
The content of the invention
For solve problems of the prior art, the invention provides a kind of stealthy light trapping structure of mobile Infrared Targets with
And infrared stealth method.
The purpose of the present invention is by the following technical programs implementing：
A kind of stealthy light trapping structure of mobile Infrared Targets, in mobile target surface, is provided with sunken light microstructured layers, and the sunken light is micro-
Structure sheaf cross section is multiple isosceles triangles, and the height of the base length and isosceles triangle of the isosceles triangle is micro-
Rice magnitude.
Further, the sunken light microstructured layers are processed into by special-shaped laser beam.
A kind of method that infrared stealth is carried out to mobile target, it is characterised in that：Comprise the following steps：
Step 1：Mobile target outer surface is cleaned；
Step 2：Required according to infrared stealth, design falls into the base of cross section isosceles triangle and height in light microstructured layers；
Step 3：Sunken light microstructured layers of the section for isosceles triangle are processed by special-shaped laser beam process technology.
Further, in step 1, dip in acetone or alcohol using cotton to clean mobile target surface, Zhi Daomian
Till cloth color no longer changes.
The invention has the beneficial effects as follows：
The stealthy light trapping structure of mobile Infrared Targets disclosed in this invention and infrared stealth method, with reference to light and the electricity of micro-structural
Magnetic coupling properties, manufacture micro-structural of the section for isosceles triangle on body surface, realize infrared sunken light, reduce mobile target
Reflectivity and emissivity, so as to reduce moving the possibility that target is detected.
Description of the drawings
Fig. 1 is the stealthy light trapping structure cross-sectional configuration schematic diagram of mobile Infrared Targets disclosed in this invention；
Fig. 2 is by using the calculated reflectance spectrum of the stealthy light trapping structure of mobile Infrared Targets disclosed in this invention.
Specific embodiment
With reference to specific embodiment, specific embodiments of the present invention is described in detail.
As shown in figure 1, the invention discloses a kind of stealthy light trapping structure of mobile Infrared Targets, in mobile target surface 1, if
It is equipped with sunken light microstructured layers 2, sunken 2 cross section of light microstructured layers is multiple isosceles triangles, the bottom of the isosceles triangle
The height of edge lengths and isosceles triangle is micron dimension, and the sunken light microstructured layers 2 are processed into by special-shaped laser beam.
The method that the introduction of lower mask body carries out infrared stealth to mobile target, comprises the following steps：
(1) mobile 1 material clean of target outer surface：Acetone or alcohol is dipped in using cotton to clean 1 multipass of mobile target surface,
Till cotton color no longer changes, demand is prepared to meet micro-structural.
(3) required according to infrared stealth, design falls into the base of the isosceles triangle in 2 cross section of light microstructured layers and high phase
Deng in the present embodiment, the bottom surface of the isosceles triangle in sunken 2 cross section of light microstructured layers and height being both designed as 10 μm.
(4) sunken light microstructured layers 2 of the section for isosceles triangle are processed by special-shaped laser beam process technology.
(5) the Infrared Reflective Spectra light good general through the micro-structural is less than the reflected light light intensity of flat samples.In this enforcement
In example, if its reflectance spectrum specifically prepares the micro-structural for the material of R=0.4 as shown in Fig. 2 adopting reflectivity, its reflectivity
0.04-0.01 is reduced to from 0.4, more than 90% is reduced；Adopt reflectivity the micro-structural is prepared for the material of R=0.8, its reflection
Rate is reduced to less than 0.4 from 0.8, reduces more than 50%；Adopting reflectivity and the micro-structural being prepared for 1 material, its reflectivity does not have
There is reduction.If preparing the micro-structural from the relatively low material of emissivity, its emission ratio compares flat samples also reduction.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to,
Although being described in detail to the present invention with reference to the foregoing embodiments, for a person skilled in the art, which still may be used
To modify to the technical scheme described in foregoing embodiments, or equivalent is carried out to which part technical characteristic.
All any modification, equivalent substitution and improvements within the spirit and principles in the present invention, made etc., should be included in the present invention's
Within protection domain.
