Full solar disk sun imager adopting two-channel atomic light filtering technology

Abstract

The invention discloses a full solar disk sun imager adopting two-channel atomic light filtering technology, which comprises a telescope (01), a light filtering sheet (02), a lambda / 4 wave plate (03), a polarizing light splitter (4), an atomic light filter (05), an atomic light filter (11), a light splitter (06), a light splitter (12), an interferometer (07), an interferometer (09), an interferometer (13), an interferometer (15), a CCD (08), a CCD (10), a CCD (14), a CCD (16) and a computer (17). The polarizing light splitter, the atomic light filters, the four interferometers, the four CCDs and the like are fixedly connected without time sequence control, thus four high-resolution spectrum images of the sun can be obtained simultaneously, and the full solar disk brightness, the Doppler velocity and the magnetic field intensity can be obtained after treatment. The technical scheme has the characteristics of scientific scheme, stable and reliable system, convenient use and the like, improves the stability and the precision of measurement of the solar magnetic field, and provides a better detecting device for observing sun and monitoring and predicting space weather.

Description

Technical field: [0001] The invention relates to an all-helios solar imager, in particular to an all-helios luminance, Doppler velocity and magnetic field intensity imager using narrow-band atomic light filtering technology. Background technique: [0002] The sun is the closest star to the earth, and it is also the star most closely related to human beings. Activities on the surface of the sun are usually relatively calm, but sometimes some complex and violent activities erupt suddenly, such as the appearance of sunspot groups, flare explosions, coronal mass ejections, etc. These violent activities will eject a large amount of matter into space, including high-energy particles, rays , interplanetary magnetic cloud, etc., and release a large amount of energy at the same time. On the one hand, the high-energy particles and rays produced directly threaten space vehicles and affect human space activities. , interfere with terrestrial radio communications and large power transmi...

AI Technical Summary

Problems solved by technology

When the sun is relatively calm, the time span of minutes will not have a great impact on the observation accuracy because of its small changes; while when the sun is active, because its various parameters change rapidly, even if the imaging time is separated by a few seconds, it will not affect the measurement accuracy. Precision and accuracy also play a role
