Description
Technical field
The utility model relates to a kind of refraction type optical scanning and surely looks like device.
Background technology
At present, optical scanning mainly utilizes the detector of very short time exposure or adopts the mode of slow scanning to carry out the spacescan imaging.But have significant disadvantages: the detector of employing short time exposure it cause the detection range performance to descend, and detector sensitivity reduces, and can not effectively bring into play the detection performance of planar array detector; The imaging mechanism of employing slow scanning mode can not carry out the fast scan imaging in space, and is longer to the detection time and the cycle of scenery, can not reflect scene image on every side in real time.Effect, scope and the cycle that this dual mode all may cause scanning can not reach the requirement of expection.
The utility model content
The purpose of this utility model provides a kind of refraction type optical scanning and surely looks like device, can effectively bring into play the maximum performance of planar array detector, carry out spacescan fast, reach the effect of quick capture space scene, can not effectively bring into play its performance and the long deficiency of detect cycle to overcome existing detector.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of refraction type optical scanning surely looks like device, comprise housing, the inside of described housing is provided with compensating prism, the top of compensating prism and bottom respectively by clutch shaft bearing and second bearing fixing on housing, the top of described housing is provided with motor, the output shaft of motor is connected with the top of described housing, and described motor is electric rotating machine or swing motor.
The beneficial effects of the utility model are: can use long planar array detector of time shutter in quick scanning, on the basis of giving full play to planar array detector performance and look-in frequency, move unchangeability in conjunction with the realization object scene imaging of scan compensation mechanism; Realized the high-velocity scanning of scenic focal point object space.

Embodiment
As shown in Figure 1, the described a kind of refraction type optical scanning of the utility model embodiment surely looks like device, comprise housing 1, the inside of described housing 1 is provided with compensating prism 2, the top of compensating prism 2 and bottom are fixed on the housing 1 by the clutch shaft bearing 3 and second bearing 4 respectively, the top of described housing 1 is provided with motor 5, and the output shaft of motor 5 is connected with the top of described housing 1.Described motor 5 is electric rotating machine or swing motor.
When the optical system high-speed motion scanned, the relative detector of image was also being done high-speed motion, if do not do compensation, detector time shutter (integral time) deficiency will become the virtual image.Speed according to image motion, compensating prism 2 in the optical scanning compensation system carries out rightabout rotatablely moving, make light in light path, produce reverse deflection, when so peripheral scene is moved, for detector, scene image does not change, image residence time lengthening, increased the integral time (time shutter) of optical detector, the effect of steady picture when reaching quick scan image.
As shown in Figure 2, when concrete the use, the optical scanning of the utility model refraction type surely connects focus adjusting mechanism 6 as the left end of device, and the inside of focus adjusting mechanism 6 is provided with first lens set 61 and second lens set 62; The refraction type optical scanning surely connects camera lens mechanism 7 as the right-hand member of device, and the inside of camera lens mechanism 7 is provided with optical mirror slip group 71; Surely look like the effect of device by the refraction type optical scanning, can guarantee the stable of the scene image that receives in the time shutter (integral time) at planar array detector, the output distinct image.
Principle of work of the present utility model is: as shown in Figure 3, detector receives the object scene light that optical mirror slip group 71 passes over, and shows the equipment of looking after treatment in the rear end and shows.System's 360 degree continuous high speeds rotate during horizontal scanning, and conversion has taken place scene image in the time shutter (integral time) of target surface 8, so can show apprehensive image.Add the refraction type optical scanning and surely look like device in camera lens, compensating prism 2 can reverse synchronous rotation, allows light that reverse displacement takes place, and guarantees the stable of the scene image that receives in the time shutter (integral time) at detector, the output distinct image.
As shown in Figure 4, the action with compensating prism 2 changes high speed swinging into by rotation.The swing of compensating prism 2 is triggered by external synchronization signal, and reverse then synchronous rotation after compensation is finished, is returned start bit rapidly.The action of control compensation prism 2 more accurately of this mode reaches better compensation effect.
The utility model refraction type optical scanning at present surely is applied to " airport birds detection system " as device, detector is a high resolving power medium wave infrared eye in the system, system high-speed scanning 360 degree panoramas, implement the round-the-clock monitoring of real time panoramic, can in time find the bird feelings around the airfield runway, for the aircraft safety landing on airport provides safeguard.And the utility model detector can be widely used in the low latitude, at a slow speed, the round-the-clock monitoring of little target.System can on the basis of giving full play to detector performance and detect cycle, realize that in conjunction with scan compensation mechanism object scene moves unchangeability using long detector of time shutter in the scanning fast; Realized the high-velocity scanning of scene image, structural design is simple.
