Detailed description of the invention
With detailed description of the invention, the present invention is described in detail below in conjunction with the accompanying drawings.
The detection device that the present invention relates to is shown in Fig. 1, mainly includes source of parallel light 1 and two dimensional motion platform 2, wave front detector
4 and sextuple sports platform 5, computer 3 etc., computer 3, two dimensional motion platform 2, sextuple sports platform 5 and wave front detector 4 composition control
System processed, computer 3, wave front detector 4 and sextuple sports platform 5 composition location closed-loop structure.
In Fig. 1, source of parallel light 1 have employed off-axis reflection source of parallel light, and is fixedly installed in two dimensional motion platform 2 work surface
On, two dimensional motion platform 2 possesses two orthogonal rotary freedoms, i.e. pitching and inclination, is used for adjusting source of parallel light 1 incidence tested greatly
The angle of visual field of visual field telescope 6.Wave front detector 4 is Hartman wavefront detector, is used for detecting wavefront information, sextuple sports platform
5 possess space six-freedom degree, for adjusting locus and the attitude of wave front detector 4.Computer 3 mainly has three works
Making, one is calculating, storage field-of-view information, controls the adjustment of two dimensional motion platform 2；Two is the wavefront processing wave front detector 4 record
Information, in the closed-loop structure of location, utilizes the inclination in wavefront information, pitching and out of focus item numerical value, and sub-aperture hot spot divides
Cloth information, by coordinates coupling relation, sends corresponding movement instruction to sextuple sports platform 5；Three is to calculate according to wavefront information
Image quality.The effect of control system is to meet in the range of full filed that visual field changes, wave front detector 4 positions and image quality meter
Calculate accurately carry out, location closed-loop structure effect be to ensure that single visual field detection in, wave front detector 4 can exactly with quilt
Survey Large Area Telescope 6 and be in confocal position.
Before image quality detects, first determine needs according to field range and the testing requirement of tested Large Area Telescope 6
The visual field of detection, can be by equal distribution formal character square, circular, as in figure 2 it is shown, make with different visual fields image point position in Fig. 2
For identifying, each visual field is numbered FOVi, the corresponding source of parallel light angle of visual field is (ui, vi), the coordinate of picture point and attitude are
(xi, yi, zi, αi, βi, γi)。
Fig. 3 gives the flow chart of whole-view field imaging quality testing, is broadly divided into four steps, makes as follows and being discussed in detail.
The first step, reference view field is demarcated, and is generally selected central vision as reference view field, is designated as FOV0, corresponding is parallel

γi-1), by sextuple sports platform 5 by wave front detector 4 motion corresponding theory position, near this picture point, find incident illumination, root
Distribution and wave front detector 4 according to sub-aperture hot spot detect the inclination in wavefront information, pitching and out of focus item data closed loop
Adjust position and the attitude of wave front detector 4, as it is shown in figure 5, left figure represents the sub-aperture hot spot distribution near ideal image point,
Left, upper part sub-aperture does not has hot spot, and present in wavefront information, inclination, pitching and out of focus item data are respectively Zn simultaneouslytilt,
Zntip, Zndefocus, now, computer is according to sub-aperture hot spot distribution form and wavefront information, by coordinates coupling relation, to
Sextuple sports platform 5 sends instruction, in closed loop procedure, adjusts movement instruction in real time, finally makes all sub-aperture all there is hot spot,
And tilt, pitching and out of focus item data reach range of allowable error etilt、etip、edefocus, now, closed-loop termination, wavefront is visited
Surveying device 4 and adjust the confocal position to tested Large Area Telescope 6, sub-aperture hot spot is distributed shown in figure as right in Fig. 5, the picture point obtained
Position and attitude data are shown below:
(x′i, y 'i, z 'i, αi-1, βi-1, γi-1)→(xi, yi, zi, αi, βi, γi)。
4th step, image quality measurement, the wavefront information measured according to wave front detector 4, computer utilizes wave front restoration
Algorithm, such as type method, field method etc., obtains restoring corrugated and the pertinent statistical parameters of its face type, and then is converted to into picture element
Amount evaluation function, Te Lieer represents than SR etc., such as following formula like that:
σ represents the RMS value restoring face, corrugated type, and λ represents the wavelength of source of parallel light 1, and other evaluation of imaging quality functions can
To calculate according to relevant conversion formula.
Control system is according to measuring visual field order, and repetition second step is to the 4th step, until completing full filed scope to become picture element
The detection of amount.
Above-described embodiment is merely to clearly illustrate the citing of the present invention, and not restriction to embodiment.Here without
Need also to give exhaustive to all of embodiment.And the obvious change thus extended out or variation are still in this
Among the protection domain of invention.
