Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
See Fig. 1, a kind of sighting device for the long-range removing of electric line foreign matter laser of the present utility model, utilize this device, can easily long-range foreign matter target 9 be observed and be aimed at, specifically comprise adjustable focus focal length video camera 1, optical filter 2, half-reflecting half mirror 3, catoptron 4, electric precise The Cloud Terrace 5, master controller 6, secondary light source 7.
Adjustable focus focal length video camera 1 vertical light axis 10 is placed, and camera lens, in the face of optical axis 10 direction, also can be parallel to infrared optical axis 10 and place, only need to add a slice transmitting mirror again; Optical filter 2 is placed on before the camera lens of video camera 1; Half-reflecting half mirror 3 is placed in infrared laser light path, places with optical axis 10 one-tenth 45 degree; Optical axis 10 end placed by catoptron 4, fixes with electric precise The Cloud Terrace 5; Electric precise The Cloud Terrace 5 is placed on after catoptron 4; Master controller 6 is connected to electric precise The Cloud Terrace 5 by control line 8, is connected to adjustable focus focal length video camera 1 by data line 13; Secondary light source 7 is in the camera lens peripheral position of video camera 1, and the optical axis of its optical axis and video camera 1 in the same way, and is in the working range of half-reflecting half mirror 3 and catoptron 4.
Faced by half-reflecting half mirror 3 one, infrared laser is thoroughly high, and another side is high anti-to visible ray; Catoptron 4 pairs of infrared lasers and visible ray height are instead; Optical filter 2 can filtering Infrared, plays protection video camera 1, improves the function of image quality.Infrared laser shines catoptron 4 by half-reflecting half mirror 3, then be reflected and be irradiated to long-range foreign matter target 9, the visible ray of long-range foreign matter target 9 surface reflection or the visible light of video camera CCD is reflexed to the reflecting surface of half-reflecting half mirror 3 by catoptron 4, then optical filter 2 is reflected to, optical filter 2 filtering veiling glare and possible high-energy throughput light, allow the camera lens visible light of video camera 1 being entered to video camera 1, thus make video camera 1 collect long-range foreign matter target 9 image.
Electric precise The Cloud Terrace 5 can rotate accurately and fast in two dimensions, thus controls Laser output direction.
Master controller 6 obtains image by video camera 1 and shows, and image centre position is infrared laser hot spot position, and master controller 6 can control electric precise The Cloud Terrace 5 and rotate, thus drives laser beam and camera coverage change.
Aiming principle of the present utility model is:
Infrared laser light beam 10, by the high saturating one side of half-reflecting half mirror 3 pairs of infrared lights, injects the reflecting surface of catoptron 4; Infrared light reflection is gone out by catoptron 4; By light path principle of reversibility, infrared laser can use light path by Laser emission to object 9 surface, the visible ray of object 9 surface reflection also can be reflected by light path, therefore the surperficial natural light of object 9 at infrared laser hot spot place can reflex to the high anti-one side of half-reflecting half mirror 3 pairs of visible rays by catoptron, and half-reflecting half mirror 3 is by the position of visible reflectance to optical filter 2; Optical filter 2 filtering infrared light, enters the camera lens of adjustable focus focal length video camera 1 by visible transmission.Because the camera lens central authorities of adjustable focus focal length video camera 1 overlap completely with the optical axis of whole light path, by this design, adjustable focus focal length camera review visual field middle position, it must be the position at infrared laser hot spot place, by regulating electric platform 5, the camera review visual field can be changed, have also been changed laser direction simultaneously, thus realize image and where see, laser is with regard to directive where function.
A kind of method of sight for the long-range removing of electric line foreign matter laser of the present utility model, concrete steps are as follows:
(A) adjustable focus focal length video camera 1 gathers incident visible ray 11, thus observes the subject image of infrared laser hot spot position, by focusing, can the convergent-divergent visual field, further and zoom out image; Have benefited from the combination of half-reflecting half mirror 3 and catoptron 4, infrared laser hot spot position remains on adjustable focus focal length video camera 1 visual field central authorities always; When dark, secondary light source 7 sends can fill-in light 12, outputs to long-range foreign matter target 9 position in the same way with infrared laser, increases brightness;
(B) image that adjustable focus focal length video camera 1 collects is presented on screen by master controller 6, control electric precise The Cloud Terrace 5 by action button or handle to rotate, catoptron 4 can be driven to rotate, thus change infrared laser exit direction and camera coverage;
(C) when long-range foreign matter target 9 is in dynamic, controller 6 calculates the trend of long-range foreign matter target 9 in real time by image algorithm, control electric precise The Cloud Terrace 5 in real time by closed loop control algorithm and follow rotation, thus realize the function of the light beam long-range foreign matter target 9 of tracking aiming all the time.
More than show and describe ultimate principle of the present utility model and 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.
