Description
Technical field
The present invention relates to space optical remote technical fields, and in particular to a kind of optical system put fastly suitable for whole star.
Background technique
Space remote sensing technology be all the time measure national science and technology level important indicator and every country it is competing
The technology mutually grasped and strongly developed, it is widely used in military surveillance exploration, environment and disaster surveillance, weather forecast, photography
The key areas such as mapping, agricultural development.Remote sensing camera is the emphasis developed in recent years, and telemetering sensing capability is high efficiency now
One of the mostly important means of Earth Information are obtained, but its temporal resolution is limited by satellite revisiting period.Super large
Breadth earth observation can effectively shorten the revisiting period of satellite target over the ground, significantly improve the timeliness of detection information.Whole star is fast
Pendulum can effectively realize super large breadth using sweeping imaging, however the movement of the quick sweeping in vertical flight direction will lead to exposure at
As generating relative motion between ground object target and detector 5 in the time, the mistake for leading to imaging as shifting and image jitter problem is brought
Very, difficulty is brought to image mosaic, is unfavorable for realizing super large breadth.It solves the problems, such as this method to be to be to meet mapping precision
It is required that the optical imaging system with fast mirror 4 (Fast Steer Mirror, abbreviation FSM).
FSM technology changes optical path, so that detecting within 5 time of integration of detector by the mobile optical element of movement mechanism
Device 5 and scene are opposing stationary, realize compensation, steady picture during the motion.FSM has the advantage that first is that bandwidth is high, response speed
Fastly；Second is that positioning accuracy is high, microradian the grade even positioning of sub-micro radian grade can be realized.Satellite during earth observation,
Due to the track movement of satellite platform, on a large scale motor-driven and earth rotation movement etc. is read fastly, will form the picture shifting of camera image planes
Vector needs FSM to carry out motion compensation to keep camera image planes and atural object opposing stationary, as shown in Figure 1, p is along rail side
To；Q is to wear rail direction (level is to the left)；M is substar optical axis direction, sets m as the optical axis before the rotation adjustment of fast mirror 4
Direction；N is FSM scanning element optical axis direction, and n corresponds to fast mirror 4 and rotates optical axis direction adjusted；Satellite carries out a wide range of
When swinging imaging, fast mirror 4 turns over the angle θ, and the light beam of reflection can turn over 2 angles θ, and the m of corresponding diagram 1 turns to p, quick reflex
After mirror 4 adjusts, keeps the focal plane 6 of optical system to stablize, i.e., compensation, steady picture are realized by FSM technology.When satellite carries out big model
When enclosing swing imaging, by the rotation of fast mirror 4 in optical system, it ensure that the camera image planes of satellite are opposite with atural object quiet
Only, it can be seen that, FSM realizes compensation, steady picture while motor-driven realization super large breadth is imaged satellite on a large scale.Currently,
FSM is mainly used in space interference measurement, laser communication, the image stabilization of aerial camera etc..But due to space remote sensing phase
The security classification of machine is higher, and the related data that related FSM is applied to space camera imaging is less, the KH-12 remote sensing satellite in the U.S.,
High resolution reaches 0.1m, and research work is broadly divided into two parts: one is image motion compensation, and two be fast anti-mirror motion compensation.
James's weber telescope in the U.S. uses Cassegrain's formula structure, and FSM is equipped at image planes, realizes image shift compensation and steady
Picture.Huge Magellan Telescope uses the structure similar with James's weber telescope, and secondary mirror FSM realizes image shift compensation
With steady picture.Foreign countries are currently in monopoly position, therefore, design a kind of novel light with FSM put fastly suitable for the whole star of satellite
System is of great importance.
Now there are refraction type, reflective and refraction-reflection three types applied to the optical system form of space camera.Satellite
Under the premise of certain altitude, the ground pixel resolution and covered ground width of system depend primarily on the angular resolution of system
And field angle, and the angular resolution of optical system is improved with the increase of system Entry pupil diameters.But the increase of Entry pupil diameters, meaning
Taste all relevant to aperture aberrations increase.It is restricted by the factors such as mechanics, calorifics, pressure in space environment, when focal length increases
It is added to (usual 300mm or more) to a certain degree, optical system generally uses reflective or refraction-reflection type scheme.This is because with coke
Away from increase, the volume and weight of optical system is presented geometric multiple and increases, under the limitation of certain volume, compared to reflective
Optical system, the focal length of refractive optical system is difficult to do greatly, and under same volume, the focal length of reflective optical system is than refraction
Formula optical system is 5~7 times big.In reflective optical system, off-axis reflection optical system is increasingly becoming Optical System Design and grinds
The hot spot studied carefully, being primarily due to off-axis reflection optical system compared to axis reflector optical system does not have central obscuration, light-use
Rate is high, and the ratio axis reflector systems that visual field can be done are much larger.Therefore off-axis reflection optical system is in current space remote sensing
And multispectral imaging field plays increasingly important role.However there is also one for traditional off-axis reflection optical system
Some insufficient, such as volume is excessive and structure not enough simplifies, without taking into account small size, simple structure while can guarantee satellite
The optical system of Fast Digital Image Stabilization and progress image shift compensation under quick motion state.
