Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] A large field of view scanning imaging device based on a solar adaptive optics system consists of a collimator 1, a wavefront corrector DM 2, an optical repeater 3, a scanning mirror 4, a beam splitter 5, a wavefront detector 6, an imaging System 7, wave front controller 8 and data processing computer 9 etc. composition. After the solar telescope 10 with large field of view observation capability images a local area of ​​the sun's surface, the collimator 1 placed at a certain distance behind the image plane of the solar telescope 10 is collimated into a parallel beam of a certain caliber, corresponding to the common The yoke position is exit pupil position A. A wavefront corrector DM 2 is installed at the exit pupil position A to correct the wavefront distortion caused by sunlight passing through the earth's surface. The solar beam ref...

Abstract

The invention provides a large-visual field scanning and imaging device based on a solar adaptive optical system, which comprises a collimator (1), a wavefront corrector DM (2), an optical repeater (3), a scanning mirror (4), a spectroscope (5), a wavefront detector (6), an imaging system (7), a wavefront controller (8) and a data processing computer (9). In the large-visual field scanning and imaging device, an exit pupil position conjugated on the ground floor is created in a traditional adaptive optical system, and the scanning mirror is additionally arranged at the position. The large-visual field scanning and imaging device has the beneficial effects that through controlling two dimension angles of the scanning mirror, large-visual field objectives are effectively divided and respectively corrected; finally, the correction ability of the solar adaptive optical system to a large-visual field activity area is realized through a data infusion method; and the complexity of the solar adaptive optical system is not remarkably increased, so that the correction ability of the solar adaptive optical system is expanded.

Description

technical field [0001] The invention relates to a scanning imaging device after performing adaptive optics correction on a large viewing field observation target, in particular to a large viewing field scanning imaging device based on a solar adaptive optical system. Background technique [0002] The solar adaptive optics system is one of the necessary means for the vast majority of solar telescopes at home and abroad, especially the large-aperture solar telescopes to successfully observe the active regions on the sun's surface. Atmospheric turbulence, especially the atmospheric turbulence at the surface layer, will seriously affect the imaging quality of solar telescopes and reduce the resolving power of observations on the solar surface. In order to give full play to the imaging capabilities of large-aperture solar telescopes and make them reach or approach the diffraction-limited observation performance, it is necessary to equip them with corresponding adaptive optics sys...
