Azimuthal telescope pupil plane and image plane mechanical racemic integration device

Abstract

The invention discloses an azimuthal telescope pupil plane and image plane mechanical racemic integration device comprising an azimuthal telescope, a rotating table, an electrical control drive, a relay optical path, a deformable mirror DM, a camera, a camera rotating table, a controller and a data processing and controlling computer. Owing to the mechanical advantages of an azimuthal frame, a majority of large-diameter telescopes adopt the structures currently in the worldwide. However, in the target tracking process, the pupil plane and image plane rotate accordingly, the atmospheric wavefront aberration cannot be measured and corrected accurately through adaptive optics due to pupil plane rotation, and continuous and stable observation results cannot be acquired by the telescope due to image plane rotation. According to the device, the pupil plane rotation is eliminated through the rotation table, the image plane rotation is eliminated through the rotating camera, additional instrument polarization is omitted, optical path integrated reflectivity reducing is avoided, and the practicality and creativity are high.

Description

technical field [0001] The invention relates to the technical field of a derotation device for pupil plane rotation and image plane rotation of a horizon telescope, in particular to an integrated device for mechanical derotation of the pupil plane and image plane of a horizon telescope. Background technique [0002] Due to the superior mechanical properties of the ground-level rack, with the continuous improvement of human requirements for the image resolution of the telescope, the aperture of the telescope is also increasing. Only the ground-level rack structure can meet the use requirements. The installation location of the telescope with the ground-level rack structure has nothing to do with the geographical latitude. At present, most large-aperture telescopes in the world use this structure. [0003] However, horizon-level telescopes also have some defects, such as pupil plane rotation and image plane rotation. [0004] The rotation of the pupil plane will make adaptive...

Problems solved by technology

[0011] The technical problem to be solved by the present invention is: for the rotation of the pupil surface of the horizon telescope, the adaptive optics cannot accurately detect the phase information of the atmospheric wavefront, and thus cannot accurately correct the influence of atmospheric disturbance on the imaging quality, so that the telescope cannot reach or approach the theoretical diffraction Limit resolution ability, unable to achieve the purpose of high resolution observation
