Optical racemization and slit scanning integrated device based on solar telescope grating spectrometer

Abstract

The invention relates to an optical racemization and slit scanning integrated device based on a solar telescope grating spectrometer. The optical racemization and slit scanning integrated device comprises a solar telescope (1), a K1 plane mirror (2), a K2 plane mirror (3), a K3 plane mirror (4), an electrical control translation stage (5), an electrical control rotating platform (6), a grating spectrometer slit (7), a grating spectrometer (8), a photoelectric detector (9), a controller (10) and a data processing and control computer (11). At present, most of solar telescopes use horizontal type rack structures, image field rotation problems are easily caused in the object tracking process by means of the structures, so that on one hand, a special image field racemization device is required to be equipped, and on the other hand, a special slit scanning device is required to be equipped to obtain three-dimensional information of a solar activity region. The optical racemization and slit scanning integrated device is simple in structure, small in occupied space, few in optical mirror planes and high in innovativeness and practicality.

Description

Technical field [0001] The invention relates to the technical field of devices for optical derotation and slit scanning of a solar telescope grating spectrometer, in particular to an integrated device for optical derotation and slit scanning based on a solar telescope grating spectrometer. Background technique [0002] The ground-level rack structure has obvious mechanical advantages, and the installation location of the solar telescope using this structure has nothing to do with geographic latitude. At present, most solar telescopes in the world adopt this structure, especially large-aperture solar telescopes. The horizontal solar telescope will produce image rotation when tracking and observing the local area of ​​the sun's surface, that is, the observation target in the field of view will rotate around the center of the visual axis, which brings the consistency of the solar telescope image and the image processing algorithm based on multi-frame accumulation A lot of inconveni...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: the optical derotation and the slit scanning mechanism of the solar telescope grating spectrometer are independent of each other in the traditional ground-level rack structure, and many optical components are used, which has a great impact on the imaging quality of the optical system and takes up space. Large size, complex control system and other problems, a kind of optical derotation and slit scanning integrated device based on solar telescope grating spectrometer is proposed, trying to realize optical derotation at the same time with the least optical components, the most compact optical structure, and the simplest control scheme and the function of slit scanning
