Large-visual field scanning and imaging device based on solar adaptive optical system

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...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: the conventional solar adaptive optics system is limited by the halo area, and its wavefront detection and correction field of view is small, so it is impossible to perform adaptive optics wavefront correction on the entire field of view of the solar telescope and Furthermore, to obtain large-field-of-view and high-resolution imaging results for local areas of the sun’s surface, a corresponding solution is proposed, trying to break through the limitation of the halo area on the wavefront correction capability of traditional solar adaptive optics
