Background technology
Along with the develop rapidly of infrared imagery technique, its range of application is more and more wider.Infrared system depends on high-quality imaging to the realization of the functions such as the search of target, tracking and aiming.The continuity that can keep image, it is clear that target image can remain, can lose objects when changing multiplying power, be that imaging system solves the optimal selection that large visual field search small field of view is differentiated.This just requires, in adopting continuous zoom optical system, to the accurate positioning control of its zoom group and compensation group with realize the temperature Active Compensation within the scope of total temperature, guarantee according to this system blur-free imaging in whole focal length continually varying process, there is no virtual focus.The positioning control system adopting at present, simple in structure, function singleness, can not realize the Active Compensation function within the scope of accurate location and total temperature simultaneously, and machine volume is huge, be subject to modern weapons miniaturization, light-weighted growth requirement, must realize the Miniaturization Design of infrared imaging machine system.
Summary of the invention
To be solved in the utility model is exactly the problem that existing infreared imaging device volume is large, can not realize the Active Compensation function within the scope of accurate location and total temperature simultaneously, a kind of two-wire servocontrol of utilizing is provided, by three dimensional fold image formation by rays, the two servo motion of the three dimensional fold optics mechanism that machine volume is little.
The two servo motion of three dimensional fold optics of the present utility model mechanism, it is characterized in that this mechanism comprises frame, guide rail, two servo motion systems and three dimensional fold optical system, guide rails assembling is in frame, two servo motion systems are arranged on guide rail, three dimensional fold optical system is arranged in two servo motion systems, two servo motion systems comprise focusing and zooming motion Zu He compensating motion mechanism group, focusing and zooming motion Zu Yu compensating motion mechanism group is from left to right arranged on guide rail successively, and along guide rail axially-movable, compensating motion mechanism group is done curvilinear path motion, focusing and zooming motion group is done linear movement, the image planes displacement that utilizes compensating motion mechanism group compensation focusing and zooming motion group to produce in zoom process, stablize image planes position.
Described focusing and zooming motion Zu Yu compensating motion mechanism group is supporting position sensor respectively, is convenient to accurate location.
Described three dimensional fold optical system comprises three catoptrons, and three catoptrons are respectively 45 ° of placements, makes light be U-shaped folding, is convenient to reduce optical system size, reduces complete machine size, weight and cost.
The two servo motion of three dimensional fold optics of the present utility model mechanism, has advantages of that volume is little, compact conformation, quality be light.Whole zoom track is short and level and smooth, utilize two servo motion systems, respectively focusing and zooming motion Zu He compensating motion mechanism group is accurately located, not only can be quantitative calculate corresponding focusing position, and use under complexity, severe environmental conditions, can realize the active compensation function within the scope of total temperature.Guaranteed the blur-free imaging in full focal range, image planes are stable, and picture element is good.
