Solar coronagraph

Abstract

The invention belongs to the solar-terrestrial space field and particularly relates to a mechanical structure of a kuafu type solar coronagraph. The solar coronagraph comprises an outer cover shading body support, an outer cover shading body, an outer diaphragm, a lens barrel, a heat collecting lens, an incident aperture diaphragm, a field diaphragm, an inner cover shading body, a light absorption groove, an Lyot diaphragm and an optical system; the outer diaphragm, the outer cover shading body, the heat collecting lens, the incident aperture diaphragm, the field diaphragm, the inner cover shading body, the light absorption groove and the Lyot diaphragm are arranged on an optical shaft which is arranged inside the lens barrel according to the order that sunlight enters into the lens barrel; the outer cover shading body is arranged on an optical shaft of a light path to shade direct sunlight to enter into the optical system; the outer cover shading body is arranged on the inner side of the wall of the lens barrel through the single column type outer cover shading body support; and the outer cover shading body support which is arranged onside a cross section of the lens barrel is perpendicular to the optical shaft. The solar coronagraph achieves effective observation to the solar corona by shading the direct sunlight.

Description

technical field [0001] The invention belongs to the field of solar-terrestrial space, and in particular relates to a mechanical structure of a Kuafu solar coronagraph. Background technique [0002] The research objects in the field of solar-terrestrial space are solar-terrestrial space physics, solar-terrestrial space weather changes, etc. Through observation of solar activities, we can understand the impact of the sun on earth space and human society, and serve aerospace, communication, navigation, and national security. Observation is an important part of this field. When observing the corona, it is necessary to cover the direct light of the sun’s photosphere. At present, the design level of coronagraphs in European and American countries is relatively mature. In my country, this field is still blank, and there is a lack of effective structural design for shielding sunlight. For the observation of the corona The effect is not ideal.
