Efficient solar simulator for solar corona observation experiments

Abstract

The invention belongs to the field of solar corona observation, aims to provide a solar simulator which is high in simulation, low in cost and more efficient, and particularly provides an efficient solar simulator for solar corona observation experiments. The efficient solar simulator for solar corona observation experiments comprises a photosphere lighting system, a photosphere imaging system, a solar corona lighting system, a collimation system and a shading system, the photosphere lighting system, the photosphere imaging system and the solar corona lighting system are disposed inside the shading system, an incident end of the collimation system is disposed inside the shading system and is in butt joint with the solar corona lighting system, and the photosphere imaging system comprises obscured glass, a first metal plate, a first lens, a second lens, an attenuation sheet and a second metal plate. Light emitted by the photosphere lighting system is homogenized by the obscured glass, homogenized light is incident to the first lens via an opening portion of the first metal plate and penetrates through the first lens prior to parallel light emergence, parallel light is incident to the second lens and then converged onto the attenuation sheet, light penetrates through the attenuation sheet prior to entering the collimation system via the solar corona lighting system, and accordingly simulated sunlight is outputted.

Description

technical field [0001] The invention belongs to the field of corona observation, and is applied in a coronagraph experiment process for coronal observation in a laboratory, and in particular relates to a high-efficiency solar simulation device used for corona observation experiments. Background technique [0002] At present, in the field of imaging instrument development for coronal observation, laboratory simulation experiments are required before the instrument is applied to actual observation, and the solar simulator has become an extremely important prerequisite. It should not only reflect the strong light of the sun, but also reflect the radiant energy gap between the photosphere and the corona and the characteristics of independent light emission. Although there are solar simulators with excellent performance in the prior art, they have many shortcomings such as high cost, large volume, and large required experimental site. Therefore, how to fully meet the above requi...
