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 optical derotation and slit scanning devices for solar telescope grating spectrometers, in particular to an integrated device for optical derotation and slit scanning based on solar telescope grating spectrometers. Background technique [0002] The ground-level rack structure has obvious mechanical advantages, and the installation location of the solar telescope adopting this structure has nothing to do with the geographical latitude. At present, most of the solar telescopes in the world adopt this structure, especially the large aperture solar telescopes. Horizontal solar telescopes will generate image rotation when tracking and observing local areas 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 will bring image consistency to the solar telescope and image processing algorithms based on multi-frame accumulation. caused ...
