Abstract
The present invention relates to a miniature target detection system with long focus and a large visual field and without movable parts, which belongs to the technical field of target detection. For developing a miniature target detection system simultaneously having long focus optical tracking imaging capability and wide visual angle search capability and having no movable parts so as to discover, identify and track spatial targets, the present invention discloses a miniature target detection system which comprises a long focus optical tracking imaging system and a wide visual angle search system, wherein the long focus optical tracking imaging system comprises a first reflector, a second reflector and a first light sensitive device. The wide visual angle search system comprises a wide visual angle lens and a second light sensitive device. The long focus optical tracking imaging system and the wide visual angle search system are coaxial and are fixedly connected to make the wide visual angle lens, the second light sensitive device, the second reflector, the first reflector and the first light sensitive device which are orderly arranged on the same axial line. The present invention has no movable parts, and consequently, the reliability of the whole system is enhanced.
Description
Technical field
The present invention relates to a kind of target detection system, belong to the target detection technical field.
Background technology
Long-focus camera or telescopic system are suitable for taking remote scenery, but field angle is little; Wide visual angle camera focus is short, and field angle is big, is suitable for taking closely and interior on a large scale scenery.Desire is observed remote and the big scenery of scope, just requires focal length long and the visual field is big, adopts single long-focus camera or telescopic system or wide visual angle camera all can not meet the demands.
Summary of the invention
The objective of the invention is to develop one and possess long-focus optical tracking imaging and wide visual angle micro target detecting system search capability, no-movable part simultaneously, with extraterrestrial target is found, recognition and tracking.
Technical scheme of the present invention is as follows: a kind of micro target detecting system of long-focus large field no-movable part, it is characterized in that: this system comprises long-focus optical tracking imaging system and wide visual angle search system, and described realization comprises first catoptron, second catoptron and first photo sensitive device to the long-focus optical tracking imaging system of identification of targets and tracking and imaging; The described wide visual angle search system that is used for ferret out comprises the wide visual angle camera lens and second photo sensitive device; Described long-focus optical tracking imaging system and coaxial being connected of wide visual angle search system, thereby make wide visual angle camera lens, second photo sensitive device, second catoptron, first catoptron and first photo sensitive device of placing successively be on the same axis, the reflecting surface subtend of first catoptron and second catoptron is provided with, the central part of first catoptron is a printing opacity, and first photo sensitive device is arranged on the center of first catoptron.
First photo sensitive device of the present invention or second photo sensitive device are high sensitivity charge-coupled device (CCD), Intensified Charge Coupled Device (ICCD), electron multiplication charge-coupled image sensor (EBCCD) or intelligent photo sensitive device.
Wide visual angle of the present invention camera lens is the camera lens that adopts the aspheric surface design, reducing the quantity of eyeglass, thereby can dwindle the size of whole detection system.
Long-focus optical tracking imaging system among the present invention has the image quality of nearly diffraction, and the imaging of the opticator of wide visual angle search system does not have vignetting.
The present invention is owing to organically combine long-focus optical tracking imaging system and wide visual angle search system, makes no-movable part of the present invention, thereby improved the reliability of total system.
Description of drawings
Fig. 1 is the structural representation of micro target detecting system.
Embodiment
Further specify concrete structure of the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, the micro target detecting system of long-focus large field no-movable part of the present invention, comprise long-focus optical tracking imaging system and wide visual angle search system, described realization comprises first catoptron 1, second catoptron 2 and first photo sensitive device 3 to the long-focus optical tracking imaging system of identification of targets and tracking and imaging; The described wide visual angle search system that is used for ferret out comprises the wide visual angle camera lens 4 and second photo sensitive device 5; Described long-focus optical tracking imaging system and wide visual angle search system utilize mechanical connection coaxial fixing, thereby make wide visual angle camera lens 4, second photo sensitive device 5, second catoptron 2, first catoptron 1 and first photo sensitive device 3 of placing successively be on the same axis.
First photo sensitive device 3 or second photo sensitive device 5 can according to circumstances be selected high sensitivity charge-coupled device (CCD), Intensified Charge Coupled Device (ICCD) or electron multiplication charge-coupled image sensor (EBCCD) for use.First photo sensitive device 3 or second photo sensitive device 5 can also be selected intelligent photo sensitive device according to operating rate and spectral range, and the photosignal of TSL250, the TSL251 that produces as TAOS company, TSL252, TSL253, TSL254, TSL255, TSL257, TSL260, models such as TSL261, TSL262 is changed intelligent photo sensitive device.
Wide visual angle camera lens 4 is the camera lenses that adopt the aspheric surface design, reducing the quantity of eyeglass, thereby can dwindle the size of whole detection system.Camera lens 4 visual fields, wide visual angle are big, are used for finding target, and carry out imaging on second photo sensitive device 5.The light signal that carries target information reflexes on second catoptron 2 through first catoptron 1 of long-focus optical tracking imaging system, converges to then on the target surface of first photo sensitive device 3 to carry out imaging.
During micro target detecting system work, at first utilize wide visual angle search system that target is searched on a large scale, after searching target, utilize long-focus optical tracking imaging system again, the light signal that carries target information is converged on the target surface of first photo sensitive device 3, discern and imaging, and then target is followed the tracks of.
Opticator also can be realized with telescopic system in the long-focus optical tracking imaging system.
