Solar corona 3D reconstruction simulation device

Abstract

The present invention relates to the solar corona observation technology field, in particular to a solar corona 3D reconstruction simulation device. The solar corona 3D reconstruction simulation device is equipped with a bottom plate, and is characterized in that a central shaft is arranged in the middle part of the bottom plate, a first shaft sleeve and a second shaft sleeve sleeve the central shaft, a first gear is fixedly connected with the first shaft sleeve, and a second gear is fixedly connected with the second shaft sleeve; the first gear is in three-phase meshing with a gear on the output shaft of a first stepping motor, and the second gear is in four-phase meshing with a gear on the output shaft of a second stepping motor; a bulb is arranged at the upper end of the central shaft,a high-transmittance glass spherical cover sleeves the bulb, and a first connecting rod and a second connecting rod are connected with the first shaft sleeve and the second shaft sleeve respectively;the other end of the first connecting rod and the other end of the second connecting rod are connected with a first external shielding coronagraph and a second external shielding coronagraph respectively, and the first external shielding coronagraph and the second external shielding coronagraph are connected with a PC separately. The solar corona 3D reconstruction simulation device has the advantages of being reasonable in structure, being simple and visual, being convenient for the classroom teaching demonstration, etc.

Description

technical field [0001] The invention relates to the field of solar observation technology and physical experiment teaching, in particular to a 3D reconstruction simulation device for the solar corona with reasonable structure, simple and intuitive, and convenient for classroom teaching demonstration. Background technique [0002] The corona is the outer layer of the sun's atmosphere, with a thickness of several million kilometers and a temperature of 1 million degrees Celsius. The light it emits is weaker than that of the chromosphere. The corona is composed of very thin fully ionized plasma, mainly protons, highly ionized ions and high-speed free electrons, whose shape changes with the size of the solar activity. The corona can be divided into three layers: the inner corona, the middle corona and the outer corona. The inner corona extends from the top of the chromosphere to 1.3 times the radius of the sun, the middle corona extends from 1.3 times the radius of the sun to 2...

Problems solved by technology

The outer cover coronagraph, that is, add an outer cover directly in front of the main mirror, and the direct sunlight that can be imaged is blocked in front of the lens barrel, which can effectively reduce the size of the scattered light inside the coronagraph, so that the outer cover The coronagraph can observe the outer corona with very weak light intensity, but its disadvantage is that the vignetting caused by the outer cover makes it impossible to observe the inner corona. Generally, the inner limit of the outer cover coronagraph observation is about two solar radii

[0005] In the past few decades, although many significant achievements have been made in the observation of the corona, further detailed observations, especially how to obtain the 3D spatial structure of the corona, are still lacking
