Outer optical transport is to the wide spectrum lens group.
6. system according to claim 5, which is characterized in that the library moral optical path includes four reflecting mirrors, wherein incident
Vertical incidence is to the second reflecting mirror after the reflection of the first reflecting mirror for light, and vertical incidence is to third after second reflecting mirror reflection
Reflecting mirror, vertical incidence reflects laggard to the 4th reflecting mirror via the 4th reflecting mirror after third reflecting mirror reflection
Enter the adjustment lens group.
7. a kind of searching method based on map cooperative detection system described in claim 1 to 6 any one, feature exist
In, comprising:
The image of multiple targets is obtained by the map cooperative detection system, and if according in the image of the multiple target
Dry image obtains the direction of motion of the multiple target；
The picture of target to be tracked is drawn by the described first two-dimentional servo servomechanism and the second two-dimentional servo servomechanism
To field of view center, the infrared spectroscopy information of the target to be tracked of field of view center is obtained, wherein include in the multiple target
The target to be tracked；
Default regional area in the direction of motion of the multiple target scans for remaining target, acquisition and tracking to residue
After target, the spectral information of remaining target is obtained, wherein the residue target is described to be tracked to remove in the multiple target
Other targets except target；
Wherein, the described first two-dimentional servo servomechanism controls the optical system in it and does that movement is faced upward in rolling and second two dimension is watched
It is motionless to take servomechanism, to pass through the described first two-dimentional servo servomechanism and the second two-dimentional servo servomechanism control
The picture of target to be tracked is pulled to field of view center by the optical system that movement is faced upward in rolling.
