Description
Technical field
The utility model is related to a kind of compound anti-detection device of defocus formula, be specifically applied to modern photoelectric instrument and
The stealthy anti-detection device of traditional optical instrument, belongs to photoelectric instrument equipment technical field.
Background technology
At present, various photoelectric instruments are widely used in army or war, the optical lens or optics knot of these instruments
Structure can usually cause the exposure of photoelectric instrument position.When there is natural lighting to be mapped to camera lens surface, camera lens can be in very big visual field
Interior generation mirror-reflection, is easily found by enemy.Because military photoelectric instrument is typically using structure of looking in the distance, there is serious opal
Effect, it is easy to found by Laser Active Detection system.Meanwhile, infrared laser blinding class weapon can be also used in battlefield, should
The powerful energy of weapon is easy to damage photoelectric instrument or human eye.
The content of the invention
The purpose of this utility model is to overcome above-mentioned weak point, so as to provide a kind of compound defocus formula anti-detection dress
Put, reflection of the photoelectric instrument to natural light can be reduced, weaken the chatoyancy of photoelectric instrument, strengthen the hidden of photoelectric instrument
Property；Meanwhile, prevent the light of the infrared laser blinding weapon of enemy from entering system, ensure photoelectric instrument and eye-safe.
According to the technical scheme that the utility model is provided, being combined the anti-detection device of defocus formula includes lens barrel, compound light bar, filter
Mating plate group and skew mirror, it is characterized in that：Compound light bar, filter set are sequentially provided with from front to back in lens barrel) and skew mirror, it is combined
Light bar is provided with multiple sub-apertures, and each side of multiple sub-apertures closely links into an integrated entity；Filter set is obliquely installed.
Further, the central axis of multiple sub-apertures and the central axis of lens barrel are parallel to each other.
Further, the tilt angle theta of filter set should be not less than the half of the compound light bar angle of visual field, meet θ ＞ ω.
Further, sub-aperture is hexagon.
Further, the focal power of skew mirror is less than 100 diopters.
Compared with the prior art the utility model has advantages below：
The utility model simple structure, compact, reasonable, the shading barrel structure for replacing commonly using using compound light bar, are easy to subtract
Small device volume, alleviator weight；Using tilted-putted filter set, while having reached transmission instrument service band light
And reflection inoperative wave band light and detection, the purpose of blinding class laser；Incline the light installed and can prevent being reflected by filter set
Line has blocked detection of the Laser Active Detection system to photoelectric instrument from compound light bar outgoing；Using filter set to laser
Reflection, can prevent blinding class laser from entering system, it is ensured that the safety of instrument and human eye；Have by being installed in the front end of optical instrument
The mode for having the skew mirror of focal power changes instrument combination focal length, effectively weaker in the case of smaller sacrifice imaging definition
The chatoyancy of optical system.
Brief description of the drawings
Fig. 1 is the utility model front view.
Fig. 2 is the front view of compound light bar of the present utility model.
Description of reference numerals：1- lens barrels, 2- are combined light bar, 3- filter sets, 4- skews mirror, 5- sub-apertures.
Specific embodiment
The utility model will be further described with reference to the embodiment in accompanying drawing below：
As shown in figure 1, the utility model mainly includes lens barrel 1, compound light bar 2, filter set 3 and skew mirror 4.Lens barrel 1
Compound light bar 2, filter set 3 and skew mirror 4 are inside sequentially provided with from front to back.
As shown in Fig. 2 the compound light bar 2 is provided with the sub-aperture 5 of multiple hexagons, each side of multiple sub-apertures 5
Closely link into an integrated entity, the transmitance of whole compound light bar 2 is improved to greatest extent.The central axis and mirror of multiple sub-apertures 5
The central axis of cylinder 1 is parallel to each other.Compound light bar 2 allows the light for having smaller angle with optical axis to pass through, it is ensured that regarded in instrument
Light outside the venue will not produce mirror-reflection.Compound light bar 2 can should be with photoelectric instrument by the ω of the angle 2 (angle of visual field) of light
The angle of visual field is consistent, and the angle of visual field of compound light bar 2 is together decided on by the maximum dimension D of sub-aperture with compound light bar length L：
The filter set 3 is obliquely installed, and the tilt angle theta of filter set 3 should be not less than the one of the compound angle of visual field of light bar 2
Half, meet θ ＞ ω.Filter set 3 is obliquely installed can enter horizontal deflection to the laser of Laser Active Detection system, so that it reflects
Light cannot be by being combined light bar, and blocking detecting devices is to the detection of optical echo and the destruction of blinding class laser wavelength.
The skew mirror 4 has certain focal power, and the focal power for offseting mirror 4 is less than 100 diopters.Skew mirror 4 and light
Electric instrument camera lens combination, changes the focal length of photoelectric instrument, imaging surface is shifted, and is sacrificing the premise of certain image quality
Under dissipate the echo of instrument outgoing, greatly weaken photoelectric instrument chatoyancy.
When using, the utility model device is directly installed on the front end of photoelectric instrument, is prevented from photoelectric instrument camera lens
The mirror-reflection on surface, weakens the chatoyancy of instrumental optics system, and protects photoelectric instrument and eye-safe.
The utility model simple structure, compact, reasonable, the shading barrel structure for replacing commonly using using compound light bar, are easy to subtract
Small device volume, alleviator weight；Using tilted-putted filter set, while having reached transmission instrument service band light
And reflection inoperative wave band light and detection, the purpose of blinding class laser.Incline the light installed and can prevent being reflected by filter set
Line has blocked detection of the Laser Active Detection system to photoelectric instrument from compound light bar outgoing；Using filter set to laser
Reflection, can prevent blinding class laser from entering system, it is ensured that the safety of instrument and human eye；Have by being installed in the front end of optical instrument
The mode for having the skew mirror of focal power changes instrument combination focal length, effectively weaker in the case of smaller sacrifice imaging definition
The chatoyancy of optical system.
